ANTISTATIC PRESSURE-SENSITIVE ADHESIVE COMPOSITION AND ANTISTATIC PRESSURE-SENSITIVE ADHESIVE OBTAINED BY USING THE SAME, ANTISTATIC PRESSURE-SENSITIVE ADHESIVE SHEET

摘要

PROBLEM TO BE SOLVED: To provide an antistatic pressure-sensitive adhesive composition with which a bleeding phenomenon over time is suppressed, which is highly transparent, which has sufficient pressure-sensitive adhesion strength, which is excellent in long-term antistatic performance, the antistatic performance of which does not deteriorate even in a high temperature and humidity condition, and which is excellent in transparency, stain resistance, and light resistance, and to provide an antistatic pressure-sensitive adhesive and an adhesive sheet.SOLUTION: The pressure-sensitive adhesive uses an antistatic pressure-sensitive adhesive composition which contains a (meth)acrylic monomer having a solubility parameter of 7-11 (cal/cm), and an ionic vinyl monomer which is soluble in the (meth)acrylic monomer and is represented by general formula (1), and furthermore, includes a (meth)acrylic resin produced by polymerizing and crosslinking the antistatic pressure-sensitive adhesive composition as a main component (in formula, Rrepresents a hydrogen atom or a methyl group, each of Rand Rindependently represents a 1-3C alkyl group or a benzyl group optionally identical to or different from each other, Y represents an oxygen atom or an NH, Z represents a 1-3C alkylene group, and Xrepresents a straight chain sulfonimide anion [(RfSO)(RfSO)N](provided that each of Rfand Rfrepresents a 1-4C perfluoroalkyl group or a fluoro group with the carbon number of zero, optionally identical to or different from each other), or a cyclic imido anion [CF(CFSO)N]).
