摘要

PROBLEM TO BE SOLVED: To provide an adhesive agent composition excellent in quick curability, less in increase of adhesive force after using under a high temperature condition, capable of being peeled with small power and further hardly generating contamination when peeled from an adherend and capable of being used for a heat resistant adhesive film for masking.SOLUTION: There is provided an acrylic adhesive composition containing (A) an acrylic resin and (B) a crosslinking agent. The crosslinking agent (B) contains an epoxy-based crosslinking agent (B1) and a titanium alkoxide-based crosslinking agent (B2), the content of the epoxy-based crosslinking agent (B1) is 1.0 to 30 pts.wt. and the content of the titanium alkoxide-based crosslinking agent (B2) is 1.5 to 30 pts.wt. based on 100 pts.wt. of the acrylic resin (A). There is provided an acrylic adhesive composition preferably having content ratio of a metal component (X) in the titanium alkoxide-based crosslinking agent (B2) to the epoxy-based crosslinking agent (B1), (X/B1) of 0.02 to 5.SELECTED DRAWING: None
