Abstract
Abstract A multilayer decorative article having in order an ink- receptive vinyl film layer, a plasticizer barrier layer, and a pressure-sensitive adhesive layer, the adhesive layer being adapted to maintain adhesion to highly plasticized vinyl substrates, and the intermediate barrier layer being capable of preventing plasticizer from migrating from the vinyl substrate into the vinyl film outer layer.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
131 words
A composite decorative article 10 adapted for adherence to a vinyl substrate 14 containing migratable plasticizer, including a polyvinyl chloride layer 22 and an adhesive layer 30 for bonding the decorative article to such vinyl substrate, characterized in that said adhesive layer 30 is a plasticizer resistant, pressure-sensitive adhesive comprising the reaction product of reactants comprising (a) acrylic acid and/or methacrylic and/or acrylamide, and/or methacrylamide, (b) an alkylacrylate and/or alkylmethacrylate, and (c) at least one additional ethylenically unsaturated monomer, and between said polyvinyl chloride film layer 22 and said adhesive layer 30 is a third layer 26 adapated to inhibit migration of vinyl plasticizers through said third layer, said compositive decorative article 10 being wrinkle resistant and said adhesive being capable of providing an adherent bond to said vinyl substrate 14.
Claim 2
Dependent Claim
131 words
A composite decorative article 10 adapted for adherence to a vinyl substrate 14 containing migratable plasticizer, including a polyvinyl chloride layer 22 and an adhesive layer 30 for bonding the decorative article to such vinyl substrate, characterized in that said adhesive layer 30 is a plasticizer resistant, pressure-sensitive adhesive comprising the reaction product of reactants comprising (a) acrylic acid and/or methacrylic and/or acrylamide, and/or methacrylamide, (b) an alkylacrylate and/or alkylmethacrylate, and (c) at least one additional ethylenically unsaturated monomer, and between said polyvinyl chloride film layer 22 and said adhesive layer 30 is a third layer 26 adapated to inhibit migration of vinyl plasticizers through said third layer, said compositive decorative article 10 being wrinkle resistant and said adhesive being capable of providing an adherent bond to said vinyl substrate 14.
Claim 3
Dependent Claim

Claim 10
Independent Claim
92 words
A method for marking a vinyl substrate having migratable plasticizers associated therewith, said method comprising bonding to said substrate a composite decorative article comprising an outer layer of polyvinyl chloride film, an intermediate layer comprising a polyurethane resin or a vinyl resin, and an underlying layer of a plasticizer resistant pressure-sensitive adhesive comprising the reaction product of reactants comprising (a) acrylic acid and/or methacrylic acid and/or acrylamide, and/or methacrylamide (b) an alkylacrylate and/or alkylmethacrylate, and (c) at least one additional ethylenically unsaturated monomer, said bonding being between said substrate and said adhesive.
Claim 11
Independent Claim
92 words
A method for marking a vinyl substrate having migratable plasticizers associated therewith, said method comprising bonding to said substrate a composite decorative article comprising an outer layer of polyvinyl chloride film, an intermediate layer comprising a polyurethane resin or a vinyl resin, and an underlying layer of a plasticizer resistant pressure-sensitive adhesive comprising the reaction product of reactants comprising (a) acrylic acid and/or methacrylic acid and/or acrylamide, and/or methacrylamide (b) an alkylacrylate and/or alkylmethacrylate, and (c) at least one additional ethylenically unsaturated monomer, said bonding being between said substrate and said adhesive.
