Active energy ray-curable release-type adhesive composition and release-type adhesive sheet

摘要

Ethylene except for acrylic resin (A), urethane (meth) acrylate compound (B), and urethane (meth) acrylate compound (B) as an active energy ray-curable peelable adhesive composition with excellent adhesive properties and stain resistance In a release-type pressure-sensitive adhesive composition containing a sexually unsaturated compound (C), a photopolymerization initiator (D) and a crosslinking agent (E), the SP value in the solubility parameter of the acrylic resin (A) is 9.9 (cal/cm 3) ^{1 /2} or more, and the urethane (meth)acrylate compound (B) has 2 to 20 ethylenically unsaturated groups, the ethylenically unsaturated compound 2 (C) has 2 to 10 ethylenically unsaturated groups, In addition, the total content of the urethane (meth) acrylate compound (B) and the ethylenically unsaturated compound (C) is 20 to 100 parts by weight based on 100 parts by weight of the acrylic resin (A), an active energy ray-curable release-type adhesive The composition is provided.
