Abstract:
1. An adhesive film comprising a substrate and an adhesive layer on said substrate, said adhesive layer comprising the following components (A) and (B): (A) a carboxyl group-containing (meth)acrylate polymer having a glass transition temperature (Tg) of 25° C. or lower, said carboxyl group-containing (meth)acrylate polymer having a percent number of repeating units of 4.0 to 25% based on the total number of repeating units of the (meth)acrylate polymer; and (B) an amino group-containing (meth)acrylate polymer having a glass transition temperature (Tg) of 75° C. or higher, said amino group-containing (meth)acrylate polymer having a percent number of repeating units of 3.5 to 15% based on the total number of repeating units of the (meth)acrylate polymer, wherein the ratio by weight of said component (A) to said component (B) is from 62:38 to 75:25.
