Title:
粘着剤組成物、及び表面保護フィルム
Document Type and Number:
Japanese Patent JP6677673
Kind Code:
B2
Abstract:
The present invention provides an adhesive composition and a surface protective film, which are excellent in the balance of adhesive force in low peel speed and high peel speed, have excellent adhesive performance with stain resistance, and have excellent antistatic performance without time degradation. The adhesive composition contains an acrylic polymer of a copolymer having an acid value of 0.1 to 1.0 by copolymerizing (A) a (meth)acrylic acid ester monomer having C1 to C18 carbon atoms of an alkyl group, (B) a copolymerizable monomer containing a hydroxyl group, (C) a copolymerizable monomer containing a carboxyl group and containing 2-ethylhexyl acrylate in a ratio of 70 parts by weight or more among 100 parts by weight of (A) (meth)acrylic acid ester monomer having C1 to C18 carbon atoms of an alkyl group. A crosslinking agent is (D) 3- or higher functional isocyanate compound, and an antistatic agent is an ionic compound having anion with the number of fluorine atoms of F7 or more and a melting point of 25 to 50°C.
