<P>PROBLEM TO BE SOLVED: To provide a transparent antistatic pressure-sensitive adhesive composition and an antistatic pressure-sensitive adhesive comprising the pressure-sensitive adhesive composition, which suppress bleeding and have excellent long-term antistatic performance and satisfactory adhesive force, and to provide a pressure-sensitive adhesive sheet having excellent transparency, contamination resistance and light resistance. <P>SOLUTION: A highly transparent pressure-sensitive adhesive for optical members, having excellent antistatic performance and capable of suppressing a bleeding phenomenon, can be obtained, by using the antistatic pressure-sensitive adhesive composition containing 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 represented by a general formula (1) and soluble in the (meth)acrylic monomer, and furthermore by using the pressure-sensitive adhesive consisting mainly of a (meth)acrylic resin obtained by polymerizing and cross-linking the antistatic pressure-sensitive adhesive composition. <P>COPYRIGHT: (C)2012,JPO&INPIT |
