ADHESIVE COMPOSITION FOR POLARIZING PLATE, POLARIZING PLATE, AND OPTICAL DISPLAY DEVICE

Provided are an adhesive composition for a polarizing plate, a polarizing plate, and an optical display device, the adhesive composition comprising an epoxy-based compound, a (meth)acrylate-based compound, a photo-acid generator, and an optical radical initiator, the (meth)acrylate-based compound comprising a mixture of a bifunctional (meth)acrylate-based compound and a monofunctional (meth)acrylate-based compound having a hydrophobic functional group, wherein the adhesive strength measured after the adhesive composition for a polarizing plate is separately applied to a PET film, a TAC film, and a COP film, to which a polarizer is then bound, followed by photo-curing, is about 200 gf/inch or more. L'invention concerne une composition adhésive pour plaque de polarisation, une plaque de polarisation et un dispositif d'affichage optique, la composition adhésive comprenant un composé à base d'époxy, un composé à base de (méth)acrylate, un générateur de photo-acide et un initiateur de radicaux optiques, le composé à base de (méth)acrylate comprenant un mélange d'un composé à base de (méth)acrylate bifonctionnel et d'un composé à base de (méth)acrylate monofonctionnel ayant un groupe fonctionnel hydrophobe, où la force d'adhérence, mesurée après que la composition adhésive pour plaque de polarisation est appliquée séparément à un film PET, un film TAC, et un film COP, auquel un polariseur est ensuite lié, suivi d'un photo-durcissement, est d'environ 200 gf/pouce ou plus. 에폭시계 화합물, (메트)아크릴레이트계 화합물, 광산 발생제 및 광 라디칼 개시제를 포함하는 편광판용 접착제 조성물이고, 상기 (메트)아크릴레이트계 화합물은 2관능성 (메트)아크릴레이트계 화합물 및 소수성 관능기를 갖는 1관능성 (메트)아크릴레이트계 화합물의 혼합물을 포함하고, 상기 편광판용 접착제 조성물을 PET 필름, TAC 필름, COP 필름 각각에 도포하고 편광자를 접합하고 광경화시킨 후 측정한 접착력이 약 200gf/inch 이상인, 편광판용 접착제 조성물, 편광판 및 광학표시장치가 제공된다.
