LIGHT LEAKAGE CONTROLLING SELF-ADHESIVE COMPOSITION AND OPTICAL FILM COATED WITH THE SAME FOR DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide a light leakage controlling self-adhesive composition reducing contraction stress of a self-adhesive to complement a light leakage phenomenon and minimizing residual stress occurring by a dimensional change difference between a base material of an optical film and the self-adhesive, and to provide an optical film coated with the composition for a display.

SOLUTION: The light leakage controlling adhesive composition includes three kinds of acrylic copolymers different in weight-average molecular weight and a crosslinking agent. The acrylic copolymers are reactive copolymers polymerized with (a) 90-99.9 pts.wt. of an alkyl acrylate having 4-12C alkyl groups and (b) 0.1-10 pts.wt. of a vinyl monomer having functional groups crosslinkable with the crosslinking agent.
