PRESSURE-SENSITIVE ADHESIVE COMPOSITION FOR OPTICAL FILM, PRESSURE-SENSITIVE ADHESIVE LAYER FOR OPTICAL FILM, PRESSURE-SENSITIVE ADHESIVE OPTICAL FILM AND IMAGE DISPLAY |
摘要 |
A pressure-sensitive adhesive composition for an optical film of the present invention comprises a (meth)acryl-based polymer (A): and a polyether compound (B) having a polyether skeleton and a reactive silyl group represented by formula (1): —SiRaM3-a at at least one terminal, wherein R represents a monovalent organic group having 1 to 20 carbon atoms and optionally having a substituent; M represents a hydroxyl group or a hydrolyzable group; and <a> represents an integer of 1 to 3, provided that in cases where two or more R groups, R groups is the same or different, and in cases where two or more M groups, M groups is the same or different. The pressure-sensitive adhesive composition for an optical film is capable of forming a pressure-sensitive adhesive layer having reworkability that enables an optical film to be easily peeled off from a liquid crystal panel or the like with no adhesive residue and satisfactory durability that prevents a bonded optical film from peeling or lifting.
