<P>PROBLEM TO BE SOLVED: To provide a self-adhesive of sufficient antistatic performance, easy to release a release film when sticking a polarizing film or phase-difference film on glass or the like. <P>SOLUTION: The self-adhesive (X) for optically functional film sticking use is provided, comprising: a carboxyl-bearing (meth)acrylate resin, wherein part of the carboxy groups form a carboxylate onium salt with an onium cation (Q) and the acid value (KOHmg/1g) of the remaining carboxy groups determined by potentiometric titration method is 50.5-86.4; and 0.001-5 pts.wt., based on 100 pts.wt. of the (meth)acrylate resin (P), of a silane coupling agent. <P>COPYRIGHT: (C)2013,JPO&INPIT |
