RADIATION-CURING COMPOSITION FOR ADHESIVE, POLARIZING PLATE, AND METHOD FOR PRODUCING POLARIZING PLATE

摘要

PPROBLEM TO BE SOLVED: To provide a radiation-curing composition for adhesives which has excellent applicability (low viscosity in a liquid state) and can produce a polarizing plate excellent in wet-heat resistance, bonding strength (peeling strength), etc., within a short time by a simple production step, to provide a polarizing plate using the composition, and to provide a method for producing a polarizing plate. PSOLUTION: The radiation-curing composition for adhesives comprises (A) an oxetanyl-containing compound, (B) an oxiranyl-containing aromatic compound, (C) an oxiranyl-containing compound other than component (B), (D) a compound having two or more hydroxy groups and having a polystyrene-based number-average molecular weight of not less than 500 as measured by gel permeation chromatography and (E) a photo acid generator. The polarizing plate 1 is composed of a polyvinyl alcohol polarizing film 2 and protective films 5 and 6 laid on both surfaces thereof through adhesive layers 3 and 4 comprising a cured product of the radiation-curing composition.
