ADHESIVE COMPOSITION, ADHESIVE LAYER, METHOD FOR PRODUCING THE SAME AND ADHESIVE SHEET

摘要

PROBLEM TO BE SOLVED: To provide a releasable adhesive composition exhibiting excellent adhesiveness after crosslinking, especially having excellent adhesiveness to a curved surface and keeping excellent discoloration resistance and weatherability after the storage over a long period, in heated state or by high-temperature treatment. SOLUTION: The adhesive composition contains 100 pts.wt. of a (meth)acrylic polymer composed of 50-99.95 wt.% (meth)acrylic monomer of general formula CH2=C(R1)COOR2(R1is hydrogen or methyl; and R2is a 2-14C alkyl group) and 0.05-5 wt.% hydroxy group-containing (meth)acrylic monomer, 0.02-2 pts.wt. of an isocyanate crosslinking agent and 0.02-2 pts.wt. of a photo-crosslinking agent.
