Solvent-based re-peeling pressure-sensitive adhesive composition and re-peeling pressure-sensitive adhesive products.

摘要

PROBLEM TO BE SOLVED: To provide a repeelable pressure-sensitive adhesive product having good characteristics, because a solvent type repeelable pressure-sensitive adhesive composition capable of forming a pressure-sensitive adhesive layer excellent in high speed peelability is found out to apply to a surface-protective film for optical films.;SOLUTION: The solvent type repeelable pressure-sensitive adhesive composition includes: a high-Tg polymer (A) having ≥0°C glass transition temperature (Tg); a low-Tg polymer (B) having a Tg lower than that of the high-Tg polymer and expressing pressure-sensitive adhesive properties; and a solvent. In the pressure-sensitive adhesive layer obtained from the pressure-sensitive adhesive composition, the high-Tg polymer (A) and the low-Tg polymer (B) are incompatible with each other and form a sea-island structure.;COPYRIGHT: (C)2012,JPO&INPIT
