Summary:PROBLEM TO BE SOLVED: To provide an adhesive for an optical member that is excellent in not only antistaticity but also durability suitable for use over a long period of time such as an application for a polarizing plate as well as adhesive force and transparency. SOLUTION: The adhesive for pasting an optical member/a glass substrate comprises a (meth)acrylate copolymer (A) bearing an active hydrogen atom-containing group (h), a crosslinking agent (B) and a silane coupling agent (C), where the copolymer (A) has a group represented by general formula (1) in its side chain and contains 20-50 wt.%, based on the weight of the copolymer (A), of a unit in which AO in general formula (1) is an oxyethylene group. -COOCH2CH(OH)CH2O-(AO)n-R (1). In the formula, R is a hydrogen atom or a 1-18C alkyl group; AO is a 2-4C oxyalkylene group; and n is a numerical value of 10-50. COPYRIGHT: (C)2010,JPO&INPIT
