ACRYLIC PRESSURE-SENSITIVE ADHESIVE COMPOSITION, ACRYLIC PRESSURE-SENSITIVE ADHESIVE LAYER, AND ACRYLIC PRESSURE-SENSITIVE ADHESIVE TAPE

An acrylic pressure-sensitive adhesive composition contains 100 parts by mass of an acrylic polymer (A), 1 to 70 parts by mass of a (meth)acrylic polymer (B) having a weight average molecular weight (Mw) of 1000@Mw<30000, and 1 to 50 parts by mass of a hydrogenated tackifying resin (C). The (meth...

More Information
Summary:An acrylic pressure-sensitive adhesive composition contains 100 parts by mass of an acrylic polymer (A), 1 to 70 parts by mass of a (meth)acrylic polymer (B) having a weight average molecular weight (Mw) of 1000@Mw<30000, and 1 to 50 parts by mass of a hydrogenated tackifying resin (C). The (meth)acrylic polymer (B) is a polymer having a weight average molecular weight smaller than that of the acrylic polymer (A) as a pressure-sensitive adhesive composition, and functions as a tackifying resin along with the hydrogenated tackifying resin (C).
