Patent ID: 8194210

Claim:
A polarizing plate comprising in the following order: a protective film comprising a hard coating layer, a first easily-adhesive layer and a first transparent substrate insoluble in a solvent having a dielectric constant of 10 or more, which are formed in that order and in direct contact with one another; a polarizer on an opposite side of the protective film to a side having the hard coating layer; and a second transparent substrate, wherein the first transparent substrate comprises a cycloolefin film, and at least one of the hard coating and easily adhesive layers contains an ultraviolet absorbent, wherein the first easily-adhesive layer comprises a copolymer latex, said copolymer latex comprising at least one member selected from the group consisting of an acrylic acid ester latex, a methacrylic acid latex, and a styrene latex, and wherein the copolymer latex is obtained by polymerization from: (a) a diolefin monomer; (b) a vinyl monomer selected from an acrylic acid ester, a methacrylic acid ester, styrene and a styrene derivative; (c) at least one kind of monomer having two or more vinyl, acryloyl, methacryloyl or allyl groups per molecule; and (d) polymerization chain transfer agents including an α-methylstyrene dimer.
