摘要： The present disclosure relates to an 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 C 1 -C 14 (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 C 1 -C 14 (meth)acrylic acid ester monomer (a) is from 70 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 15 percent by weight, based on the total weight of the monomer composition.
The present disclosure further relates to a method for producing a graphic on a substrate using said adhesive film.

摘要： An object of the present invention is to provide a pressure-sensitive adhesive composition that enables a pressure-sensitive adhesive layer to be formed, wherein the pressure-sensitive adhesive layer has a low dielectric constant, is excellent in level difference conformability and transparency while maintaining adhesive strength and adhesion reliability at high temperatures, and suitable for laminating a metal mesh film and the like. The pressure-sensitive adhesive composition of the present invention contains an acrylic polymer (A), a mixture of monomer components constituting the acrylic polymer (A) or a partially polymerized product of a mixture of monomer components constituting the acrylic polymer (A), and a hydrogenated polyolefinic resin (B) that exhibits liquid flowability at 25°C. The pressure-sensitive adhesive composition comprises a branched-chain alkyl group having 10 to 24 carbon atoms as a monomer component. The hydrogenated polyolefinic resin (B) has a number average molecular weight (Mn) of 1000 to 5000 and a polydispersity (Mw/Mn) of 2.0 or less. The hydrogenated polyolefinic resin (B) contains at least one selected from the group consisting of a hydrogenated polyolefin and a hydrogenated polyolefin polyol. The pressure-sensitive adhesive composition comprises 3 to 35 parts by weight of the hydrogenated polyolefinic resin (B) based on 100 parts by weight of the acrylic polymer (A) .
