Abstract
Abstract A process for producing decorative sheets having an embossed pattern corresponding to a printed pattern layer, the process including the steps of: (a) forming a printed pattern layer on a base paper of the decorative sheet by use of a printing ink containing (i) a curing agent or a polymerization catalyst and (ii) a curable rein, the curing or catalytic action of the curing agent and polymerization catalyst being blocked and thereby inactivated, the printing ink being liquid repellant; (b) releasing the blocked state of the curing agent or polymerization catalyst thereby curing the curable resin in the printed pattern layer; (c) coating the whole surface of the printed pattern layer with a coating agent for formation of a top coating layer; and (d) solidifying the coating agent thereby forming the top coating layer of which the portions corresponding to the liquid repellant printed pattern layer are concaved.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
146 words
A process for producing decorative sheets having an embossed pattern corresponding to a printed pattern layer, said process comprising the steps of: forming a printed pattern layer on a base paper for the decorative sheet by use of a printing ink containing (a) a current agent or a polymerization catalyst and (b) a curable resin, the curing or catalytic action of said curing agent and polymerization catalyst being blocked and thereby inactivated, said printing ink being liquid repellent; releasing the block state of said curing agent or polymerization catalyst thereby curing said curable resin in said printed pattern layer; coating the whole surface of said printed pattern layer with a coating agent for the formation of a top coating layer; and solidifying said coating agent thereby forming the top coating layer of which the portions corresponding to the liquid repellent printed pattern layer are made concaved.
Claim 2
Dependent Claim
146 words
A process for producing decorative sheets having an embossed pattern corresponding to a printed pattern layer, said process comprising the steps of: forming a printed pattern layer on a base paper for the decorative sheet by use of a printing ink containing (a) a current agent or a polymerization catalyst and (b) a curable resin, the curing or catalytic action of said curing agent and polymerization catalyst being blocked and thereby inactivated, said printing ink being liquid repellent; releasing the block state of said curing agent or polymerization catalyst thereby curing said curable resin in said printed pattern layer; coating the whole surface of said printed pattern layer with a coating agent for the formation of a top coating layer; and solidifying said coating agent thereby forming the top coating layer of which the portions corresponding to the liquid repellent printed pattern layer are made concaved.
Claim 3
Dependent Claim
51 words
A process according to claim 1, wherein a polymerization catalyst is present and said catalyst, the catalytic action of which is blocked, is an amine salt of p-toluenesulfonic acid, and the curable resin is at least one resin selected from the group consisting of melamine resins, urea resins and alkyd resins.
Claim 4
Dependent Claim
40 words
A process according to claim 1, wherein a curing agent is present and said curing agent, the curing agent of which is blocked, is an isocyanate compound reacted with a blocking agent, and said curable resin is an urethane resin.
Claim 5
Dependent Claim
36 words
A process according to claim 1, wherein a curing agent is present and said curing agent, the curing action of which is blocked, is a microencapsulated aminated compound, and said curable resin is an epoxy resin.
Claim 6
Dependent Claim
33 words
A process according to claim 1, further comprising the steps of impregnating said base paper with a resin liquid and drying the impregnated base paper prior to formation of said top coating layer.
Claim 7
Dependent Claim
157 words
A process for producing decorative plates having an embossed pattern corresponding to a printed pattern layer, said process comprising the steps of: forming a printed pattern layer on a base paper by use of a printing ink containing (a) a curing agent or a polymerization catalyst and (b) a curable resin, the curing or catalytic action of said curing agent and polymerization catalyst being blocked and thereby inactivated, said printing ink being liquid repellent; releasing the block state of said curing agent or polymerization catalyst thereby curing said curable resin in said printed pattern layer; plastering said base paper to a substrate for the decorative plates via an adhesive layer; coating the whole surface of said printed pattern layer with a coating agent for the formation of a top coating layer; and solidifying said coating agent thereby forming the top coating layer of which the portions corresponding to the liquid repellent printed pattern layer are made concaved.
Claim 8
Dependent Claim
157 words
A process for producing decorative plates having an embossed pattern corresponding to a printed pattern layer, said process comprising the steps of: forming a printed pattern layer on a base paper by use of a printing ink containing (a) a curing agent or a polymerization catalyst and (b) a curable resin, the curing or catalytic action of said curing agent and polymerization catalyst being blocked and thereby inactivated, said printing ink being liquid repellent; releasing the block state of said curing agent or polymerization catalyst thereby curing said curable resin in said printed pattern layer; plastering said base paper to a substrate for the decorative plates via an adhesive layer; coating the whole surface of said printed pattern layer with a coating agent for the formation of a top coating layer; and solidifying said coating agent thereby forming the top coating layer of which the portions corresponding to the liquid repellent printed pattern layer are made concaved.
Claim 9
Dependent Claim
170 words
A process for producing decorative plates having an embossed pattern corresponding to a printed pattern layer, said process comprising the steps of: forming a printed pattern layer on a base paper by use of a printing ink containing (a) a curing agent or a polymerization catalyst and (b) a curable resin, the curing or catalytic action of said curing agent and polymerization catalyst being blocked and thereby inactivated, said printing ink being liquid repellent; releasing the block state of said curing agent or polymerization catalyst thereby curing said curable resin in said printed pattern layer; impregnating said base paper with a resin liquid; drying the impregnated base paper; plastering said base paper to a substrate for the decorative plates via an adhesive layer; coating the whole surface of said printed pattern layer with a coating agent for the formation of a top coating layer; and solidifying said coating agent thereby forming the top coating layer of which the portions corresponding to the liquid repellent printed pattern layer are made concaved.
Claim 10
Dependent Claim
170 words
A process for producing decorative plates having an embossed pattern corresponding to a printed pattern layer, said process comprising the steps of: forming a printed pattern layer on a base paper by use of a printing ink containing (a) a curing agent or a polymerization catalyst and (b) a curable resin, the curing or catalytic action of said curing agent and polymerization catalyst being blocked and thereby inactivated, said printing ink being liquid repellent; releasing the block state of said curing agent or polymerization catalyst thereby curing said curable resin in said printed pattern layer; impregnating said base paper with a resin liquid; drying the impregnated base paper; plastering said base paper to a substrate for the decorative plates via an adhesive layer; coating the whole surface of said printed pattern layer with a coating agent for the formation of a top coating layer; and solidifying said coating agent thereby forming the top coating layer of which the portions corresponding to the liquid repellent printed pattern layer are made concaved.
