ADHESIVE COMPOSITION FOR OPTICAL FILM, ADHESIVE LAYER FOR OPTICAL FILM, OPTICAL FILM WITH ADHESIVE LAYER, AND IMAGE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an adhesive composition for an optical film, from which an adhesive layer capable of achieving both of rework property and durability after long-term storage can be formed.SOLUTION: (The adhesive composition for an optical film comprises a (meth)acrylic polymer (A) and a polyether compound (B) having a reactive silyl group represented by formula (1) below. In the formula, Rrepresents a hydrocarbon group having 1 to 10 carbon atoms; t represents an integer of 3 or 4; Rrepresents a monovalent organic group having 1 to 20 carbon atoms which may have a substituent; M represents a hydrolyzable group; a represents an integer of 0 to 2; Rrepresents an alkylene group having 2 to 4 carbon atoms; Rrepresents an alkylene group having 1 to 20 carbon atoms; r represents an integer of 1 to 10; and when Rand M are present in plural numbers, the plurality of R may be the same or different from one another.SELECTED DRAWING: None
