ACRYLIC ADHESIVE COMPOSITION, ACRYLIC ADHESIVE LAYER, AND ACRYLIC ADHESIVE TAPE

An acrylic adhesive composition contains: 100 parts by mass of an acrylic polymer (A) ; 1 - 70 parts by mass of a (meth) acrylic polymer (B) having a weight average molecular weight of at least 1,000 and less than 30,000; and 1 - 50 parts by mass of a hydrogenated tackifier resin (C). The (meth) acr...

More Information
Summary:An acrylic adhesive composition contains: 100 parts by mass of an acrylic polymer (A) ; 1 - 70 parts by mass of a (meth) acrylic polymer (B) having a weight average molecular weight of at least 1,000 and less than 30,000; and 1 - 50 parts by mass of a hydrogenated tackifier resin (C). The (meth) acrylic polymer (B) is a polymer having a lower weight average molecular weight than the acrylic polymer (A) acting as an adhesive composition, and functions as a tackifier resin together with the hydrogenated tackifier resin (C).
