Abstract
Abstract A photo-curable adhesive composition for glass lamination, which comprises: (A) 100 parts by weight of a (meth)acrylate monomer represented by the formula: ##STR1## where R 1 is a hydrogen atom or a CH 3 -- group, each of R 2 , R 3 and R 4 is a straight-chained or branched alkylene group, each of n 1 and n 4 is an integer of at least 1 and each of n 2 and n 3 is an integer of 0 or at least 1, and having a molecular weight of from about 116 to about 5,000; (B) from 0.1 to 5 parts by weight of a photosensitizer; (C) from 0 to 5 parts by weight of a silane coupling agent; and (D) from 0 to 100 parts by weight of a plasticizer.
