Abstract
Abstract A protective vinyl transfer sheet material and a method for laminating such transfer sheet material to a vinyl substrate. The transfer sheet material consists of a film of plasticized vinyl resin releasably supported with measurable adhesion on one side of a continuous, flexible, non-fibrous cellulosic carrier, particularly regenerated cellulose sheet. In the method of the present invention, the vinyl film is bonded under pressure with heat to the vinyl substrate, after which the cellulosic carrier may be readily stripped from the laminate, leaving the firmly bonded vinyl film as a protective overcoating for the substrate.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
149 words
A method of preparing a protected substrate comprising: (a) contacting a vinyl chloride polymer or copolymer substrate with an/exposed film surface of a transfer sheet material, wherein the transfer sheet material comprises (1) a continuous, flexible, non-fibrous cellulosic carrier and (2) a film of plasticized vinyl chloride and vinyl acetate copolymer resin releasably adhered directly onto one side of the non-fibrous cellulosic carrier, the copolymer resin consisting essentially of about 75% to about 95% vinyl chloride and of about 5% to 25% vinyl acetate, all percentages by weight based on the copolymer resin weight, and from about 5 to 20 parts of plasticizer per hundred parts of copolymer resin; b. pressing, in the presence of heat, the contacting surfaces of the transfer sheet film and the substrate so as to provide a laminate in which the film is tenaciously bonded to the substrate; and c. thereafter cooling the laminate.
Claim 2
Independent Claim
149 words
A method of preparing a protected substrate comprising: (a) contacting a vinyl chloride polymer or copolymer substrate with an/exposed film surface of a transfer sheet material, wherein the transfer sheet material comprises (1) a continuous, flexible, non-fibrous cellulosic carrier and (2) a film of plasticized vinyl chloride and vinyl acetate copolymer resin releasably adhered directly onto one side of the non-fibrous cellulosic carrier, the copolymer resin consisting essentially of about 75% to about 95% vinyl chloride and of about 5% to 25% vinyl acetate, all percentages by weight based on the copolymer resin weight, and from about 5 to 20 parts of plasticizer per hundred parts of copolymer resin; b. pressing, in the presence of heat, the contacting surfaces of the transfer sheet film and the substrate so as to provide a laminate in which the film is tenaciously bonded to the substrate; and c. thereafter cooling the laminate.
Claim 3
Dependent Claim
27 words
A method as defined in claim 1, further comprising stripping the non-fibrous cellulosic carrier from the laminate, leaving the vinyl film tenaciously bonded to the vinyl substrate
Claim 4
Dependent Claim
19 words
A method as defined in claim 1, wherein the continuous, flexible non-fibrous cellulosic carrier is plasticized, transparent regenerated cellulose.
Claim 5
Dependent Claim
16 words
A method as defined in claim 3, wherein the regenerated cellulose sheet is plasticized with glycerine.
Claim 6
Dependent Claim
32 words
A method as defined in claim 1, wherein the vinyl copolymer resin consists of about 86% vinyl chloride and about 14% vinyl acetate, all percentages by weight based on the copolymer weight.
Claim 7
Dependent Claim
34 words
A method as defined in claim 2, wherein the vinyl film of the transfer sheet material is transparent and wherein the exposed vinyl film surface of the transfer sheet material has indicia printed thereon.
Claim 8
Dependent Claim
34 words
A method as defined in claim 5, wherein the vinyl film of the transfer sheet material is transparent and wherein the exposed vinyl film surface of the transfer sheet material has indicia printed thereon.
Claim 9
Dependent Claim
9 words
A product made by the method of claim 2.
Claim 10
Dependent Claim
9 words
A product made by the method of claim 6.
Claim 11
Dependent Claim
82 words
A transfer sheet material which comprises a continuous, flexible, non-fibrous cellulosic carrier and (b) a film of plasticized vinyl chloride and vinyl acetate copolymer resin releasably adhered directly onto one side of the non-fibrous cellulosic carrier, the copolymer resin consisting essentially of about 75% to about 95% vinyl chloride and of about 5% to 25% vinyl acetate, all percentages by weight based on the copolymer resin weight, and from about 5 to 20 parts of plasticizer per hundred parts of copolymer resin.
Claim 12
Dependent Claim
82 words
A transfer sheet material which comprises a continuous, flexible, non-fibrous cellulosic carrier and (b) a film of plasticized vinyl chloride and vinyl acetate copolymer resin releasably adhered directly onto one side of the non-fibrous cellulosic carrier, the copolymer resin consisting essentially of about 75% to about 95% vinyl chloride and of about 5% to 25% vinyl acetate, all percentages by weight based on the copolymer resin weight, and from about 5 to 20 parts of plasticizer per hundred parts of copolymer resin.
