ADHESIVE COMPOSITION FOR OPTICAL FILM, ADHESIVE LAYER FOR OPTICAL FILM, AND ADHESIVE OPTICAL FILM, AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/126054
Kind Code:
A1
Abstract:
Disclosed is an adhesive composition for an optical film, which is characterized by comprising: a (meth)acrylic polymer (A); and a polyether compound (B) having a polyether skeleton and also having a reactive silyl group represented by general formula (1): -SiRaM3-a (wherein R represents a monovalent organic group having 1 to 20 carbon atoms which may have a substituent; M represents a hydroxy group or a hydrolysable group; and a represents an integer of 1 to 3, wherein when multiple R's are present, the multiple R's may be the same as or different from each other, and when multiple M's are present, the multiple M's may be the same as or different from each other) at at least one terminal. The adhesive composition for an optical film enables the formation of an adhesive layer having such a level of a rework property that the optical film can be removed readily from a liquid crystal panel or the like without leaving no adhesive deposit on the optical film, and also having such a level of durability that the occurrence of detachment or partial removal of the optical film can be prevented when the optical film is bonded to the adhesive layer.
