Title:
粘着剤組成物およびそれを塗布してなる表面保護フィルム
Document Type and Number:
Japanese Patent JP4096209
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive composition which has an appropriate level of adhesion as well as removability and is antistatic by itself, remains no stain after removal and is useful as a surface-protecting film of high economy. SOLUTION: This pressure-sensitive adhesive composition is prepared by adding 0.1-5 pts.wt. of a cross-linking agent to 100 pts.wt. of an acrylic copolymer containing (a) 65-98.4wt.% of an acrylic alkyl ester having a 1-90 alkyl group, (b) 0.5-10wt.% of a copolymerizable unsaturated monomer bearing hydroxyl group and/or carboxyl group, (c) 1-20wt.% of a (meth)acrylic alkyl ester bearing a 16-22C alkyl group and (d) 0.1-5wt.% of a reactive emulsifier. It shows an adhesive power of <=50g/inch 20 minutes after adhesion to stainless steel at 25 deg.C, and 150g/inch 4 hours after adhesion and heating at 95 deg.C. In addition, the surface resistivity of the glue surface applied on the polyester base film is <=10<11> Ω.
