Adhesive film and method of making a graphic

Abstract

The present disclosure relates to an adhesive film for applying onto vehicles, the adhesive film comprising a polyvinyl chloride film having opposite first and second major sides, the first major side having an adhesive layer protected by a release liner, wherein the adhesive layer comprises a pressure sensitive adhesive, and wherein the pressure sensitive adhesive is made from a curable precursor comprising an acrylic copolymer and a crosslinker, and wherein the glass transition temperature of the acrylic copolymer is at least −30° C., as calculated using the Fox Equation, and wherein the acrylic copolymer is made by copolymerization of a monomer composition, the monomer composition comprising (a) a C1-C14 (meth)acrylic acid ester monomer, (b) an acid functional, ethylenically unsaturated polar monomer, and (c) a non-acid functional, ethylenically unsaturated polar monomer, and wherein the amount of the C1-C14 (meth)acrylic acid ester monomer (a) is from more than 75 to 98 percent by weight, based on the total weight of the monomer composition, and wherein the amount of the acid functional, ethylenically unsaturated polar monomer (b) is from 1 to 15 percent by weight, based on the total weight of the monomer composition, and wherein the amount of the non-acid functional, ethylenically unsaturated polar monomer (c) is from 1 to less than 10 percent by weight, based on the total weight of the monomer composition, and wherein the non-acid functional, ethylenically unsaturated polar monomer (c) is a nitrogen containing non-acid functional, ethylenically unsaturated polar monomer, and wherein the molar ratio of the acid functional, ethylenically unsaturated polar monomer to the non-acid functional, ethylenically unsaturated polar monomer in the monomer composition is at least 0.6. The present disclosure further relates to a method for producing a graphic on a substrate using said adhesive film.
