<P>PROBLEM TO BE SOLVED: To provide a photocurable adhesive which firmly joins not only a polarizing film and a thermoplastic norbornene-based resin film to each other but also firmly joins the polarizing film and one of various protective films such as a cellulose acetate-based protective film, an acryl resin film etc. in the bonding even when used as a thin adhesive layer with thickness of less than 3 μm, of which the pot life is as long as one month or more, and which is non-solvent type and has low viscosity, and with which application of thin film uniform coating with thickness of less than 3 μm is conducted with excellent productivity, for the purpose of improving the productivity, reducing the cost of equipment, reducing the cost of materials, improving adhesion property, and improving a degree of flexibility in combination and construction of the protective film etc. in manufacturing a polarizing plate, and to provide the polarizing plate using the same. <P>SOLUTION: The photocurable adhesive composition at least includes: a hydroxy group-containing alkyl (meth)acrylate of 70-98 wt.% (a); a photo-polymerization initiator of 0.5-10 wt.% (b); and a polyisocyanate of 1.5-20 wt.% (c). <P>COPYRIGHT: (C)2010,JPO&INPIT |
