| 简介 |
Disclosed is a solvent-type removable adhesive composition which comprises a high-Tg polymer (A) having a glass transition temperature (Tg) of 0°C or higher, a low-Tg polymer (B) having a Tg lower than that of the high-Tg polymer and also having a pressure-sensitive adhesion property, and a solvent. In an adhesive layer produced by using the adhesive composition, the high-Tg polymer (A) and the low-Tg polymer (B) are not dissolved in each other and form a sea-island structure, wherein the high-Tg polymer (A) forms an island phase and the low-Tg polymer (B) forms a sea phase. The composition enables to form an adhesive layer having an excellent high-speed peeling property when used as a surface protection film for an optical film. |
