Abstract
Provided are a polarizing plate and an optical display device comprising same, wherein: the polarizing plate comprises a polarizer, a protection film formed on the surface of the polarizer, and a barrier layer formed on the other surface of the polarizer; the barrier layer is formed of a composition comprising a (meth)acryl-based copolymer, a curing agent, and a silane coupler; and the curing agent comprises a mixture of: a polyisocyanate curing agent containing a plurality of units, each containing an entirety of an alkylene group of two or more carbon atoms having a urethane bonding; and a polyisocyanate curing agent containing an isocyanurate group.
Claims18
A polarizing plate comprising:
- a polarizer;
- a protective film formed on one surface of the polarizer;
- and
- a barrier layer formed on the other surface of the polarizer,
- wherein the barrier layer is formed of a composition comprising
- a (meth)acrylic copolymer,
- a curing agent, and
- a silane coupling agent,
- the curing agent comprising a mixture of
- a polyisocyanate curing agent comprising a plurality of units, each containing an alkylene group having a urethane bond and at least two carbon atoms, and an isocyanurate group-containing polyisocyanate curing agent comprising an isocyanurate of an aromatic isocyanate compound, and
- wherein the aromatic isocyanate compound is at least one selected from among toluene diisocyanate, xylylene diisocyanate, halogenated toluene diisocyanate, phenylene diisocyanate, or tetramethyl-xylylene diisocyanate.
