<P>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. <P>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<SP POS="POST">3</SP>)<SP POS="POST">0.5</SP>, 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, R<SB POS="POST">1</SB>represents a hydrogen atom or a methyl group, each of R<SB POS="POST">2</SB>and R<SB POS="POST">3</SB>independently 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 X<SP POS="POST">-</SP>represents a straight chain sulfonimide anion [(Rf<SP POS="POST">1</SP>SO<SB POS="POST">2</SB>)(Rf<SP POS="POST">2</SP>SO<SB POS="POST">2</SB>)N]<SP POS="POST">-</SP>(provided that each of Rf<SP POS="POST">1</SP>and Rf<SP POS="POST">2</SP>represents 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<SB POS="POST">2</SB>(CF<SB POS="POST">2</SB>SO<SB POS="POST">2</SB>)<SB POS="POST">2</SB>N]<SP POS="POST">-</SP>). <P>COPYRIGHT: (C)2012,JPO&INPIT |
