ADHESIVE COMPOSITION FOR HEAT-RESISTANT ADHESIVE FILM, ADHESIVE FOR HEAT-RESISTANT ADHESIVE FILM PRODUCED BY CROSSLINKING THE SAME, AND USE FOR THE ADHESIVE

摘要

PROBLEM TO BE SOLVED: To provide an adhesive composition for heat-resistant adhesive film which hardly stains an adherend when the film is peeled off from the adherend after being used under high temperature, has a sufficient adhesive property, and is economically efficient because the aging period during film production is short, and also to provide an adhesive for heat-resistant adhesive film produced by crosslinking the same and uses for the adhesive.

SOLUTION: The adhesive composition for a heat-resistant adhesive film includes an acrylic resin (A) which is obtained by copolymerizing a monomer component [I] including a nitrogen atom-containing monomer (a1) and has a glass transition temperature of ≥-40°C. The adhesive for heat-resistant adhesive film is made by crosslinking the adhesive composition containing a crosslinking agent (B). The heat-resistant adhesive film, such as a heat-resistant adhesive masking film, is characterized in that the film is covered with an adhesive layer containing the adhesive. Methods for using the heat-resistant masking adhesive film are also provided.
