<P>PROBLEM TO BE SOLVED: To provide a light-curing adhesive which strongly bonds a polarizing film and a cellulosic protective film even for an adhesive layer is a thin layer, having a thickness of less than 3 μm for realizing improvement in productivity, reduction in equipment cost, reduction in material cost and improvement in adhesive properties with the cellulosic protective film, upon the manufacture of a polarizing plate, and which is solventless type and has low viscosity, and which can apply thin film uniform coating with less than 3 μm, with proper productivity, and to provide a polarizing plate that uses the light-curing adhesive. <P>SOLUTION: Composition of the light-curing adhesive includes (a) 30 to 88 wt.% of hydroxy group-containing alkyl (meth)acrylate, (b) 10 to 45 wt.% of 2-hydroxy-3-phenoxypropyl (meth)acrylate, (c) 0.5 to 10 wt.% of a photopolymerization initiator, and (d) 1.5 to 15 wt.% of polyisocyanate. <P>COPYRIGHT: (C)2010,JPO&INPIT |
