Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
97 words
A method for producing an embossed interior finishing material having superior cigarette mark resistance, which comprises coating a composition comprising a vinyl chloride polymer, a reactive plasticizer, a blowing agent and a light sensitizer on a base material (A), irradiating ultraviolet light partly onto the coated base material, heating the coated base material to form a foamed undercoat layer (B), coating a composition comprising a vinyl chloride polymer, a reactive plasticizer and a light sensitizing agent on said undercoat layer (B), and then irradiating ultraviolet light onto the resulting laminate to form a top coat layer (C).
Claim 2
Independent Claim
97 words
A method for producing an embossed interior finishing material having superior cigarette mark resistance, which comprises coating a composition comprising a vinyl chloride polymer, a reactive plasticizer, a blowing agent and a light sensitizer on a base material (A), irradiating ultraviolet light partly onto the coated base material, heating the coated base material to form a foamed undercoat layer (B), coating a composition comprising a vinyl chloride polymer, a reactive plasticizer and a light sensitizing agent on said undercoat layer (B), and then irradiating ultraviolet light onto the resulting laminate to form a top coat layer (C).
Claim 3
Dependent Claim
57 words
The method of claim 1 wherein said base material (A) is selected from the group consisting of an asbestos sheet, a glass fiber-incorporated polyvinyl chloride sheet, a polyvinyl chloride sheet, a foamed polyvinyl chloride sheet, a flax felt, a cotton cloth, a nonwoven cloth, paper, a plywood, a particle board, a slate plate and a steel plate.
Claim 4
Dependent Claim
26 words
The method of claim 1 wherein said reactive plasticizer is a compound which has at least two polymerizable unsaturated bonds, and plasticizes the vinyl chloride polymer.
Claim 5
Dependent Claim
26 words
The method of claim 1 wherein said light sensitizer is a compound which is excited by ultraviolet radiation to induce a reaction of the reactive plasticizer.
Claim 6
Dependent Claim
13 words
The method of claim 1 wherein said undercoat layer (B) is partially foamed.
Claim 7
Dependent Claim
69 words
The method of claim 1 wherein the partial irradiation of ultraviolet light for the formation of the undercoat layer (B) is carried out by irradiating ultraviolet light through an ink containing an ultraviolet shielding ink, a paint having an effect of shielding ultraviolet light, an ultraviolet-impervious plastic film, a metal foil, paper, a wooden plate or a cloth printed or coated partly on the surface of the undercoat layer.
Claim 8
Independent Claim
142 words
A method for producing an embossed interior finishing material having superior cigarette mark resistance, which comprises coating a sol for the formation of an undercoat layer (B) comprising a vinyl chloride polymer, a reactive plasticizer, a blowing agent and a light sensitizer on a base material (A), heating the coating to convert the coating to a semi-gel, partly printing or coating an ink containing an ultraviolet-shielding agent, a paint having an effect of shielding ultraviolet light, an ultraviolet-impervious plastic film, a metal foil, paper, a wooden plate or a cloth on the semi-gel layer, then coating a transparent sheet for the formation of a top coat layer (C) obtained from a vinyl chloride polymer, a reactive plasticizer and a light sensitizer on the printed or coated layer, irradiating ultraviolet light onto the resulting laminate, and heating the laminate to provide a foam.
Claim 9
Independent Claim
142 words
A method for producing an embossed interior finishing material having superior cigarette mark resistance, which comprises coating a sol for the formation of an undercoat layer (B) comprising a vinyl chloride polymer, a reactive plasticizer, a blowing agent and a light sensitizer on a base material (A), heating the coating to convert the coating to a semi-gel, partly printing or coating an ink containing an ultraviolet-shielding agent, a paint having an effect of shielding ultraviolet light, an ultraviolet-impervious plastic film, a metal foil, paper, a wooden plate or a cloth on the semi-gel layer, then coating a transparent sheet for the formation of a top coat layer (C) obtained from a vinyl chloride polymer, a reactive plasticizer and a light sensitizer on the printed or coated layer, irradiating ultraviolet light onto the resulting laminate, and heating the laminate to provide a foam.
Claim 10
Dependent Claim

The method of claim 1 or 7 wherein the sol for the formation of the undercoat layer (B) is coated to a thickness of 0.2 to 3 mm on the base material (A).
Claim 11
Dependent Claim
18 words
A floor material composed of the interior finishing material obtained by the method of claim 1 or 7.
Claim 12
Dependent Claim
19 words
A wall material composed of the interior finishing coating material obtained by the method of claim 1 or 7.
Claim 13
Dependent Claim
18 words
A leather-like material composed of the interior finishing material obtained by the method of claim 1 or 7.
Claim 14
Dependent Claim
18 words
A decorative laminate composed of the interior finishing material obtained by the method of claim 1 or 7.
Claim 15
Dependent Claim
20 words
A polyvinyl chloride-coated steel sheet composed of the interior finishing material obtained by the method of claim 1 or 7.
