POLYESTER-BASED SELF-ADHESIVE COMPOSITION, AND POLYESTER-BASED SELF-ADHESIVE, AND SELF-ADHESIVE SHEET USING THE SELF-ADHESIVE

摘要

PROBLEM TO BE SOLVED: To provide a polyester-based self-adhesive composition usable as a self-adhesive because of being low in crystallinity and excellent in solubility to solvents, and also excellent in initial tackiness and tackiness after being left to stand under high-temperature and high-humidity conditions.

SOLUTION: The polyester-based self-adhesive composition includes (A) a polyester resin having a cyclohexane structural moiety and isophthalic acid-derived structural moiety, wherein the content of the cyclohexane structural moiety to the whole polyester resin stands at 15-50 wt.%.
