PHOTOCURABLE ADHESIVE, POLARIZING PLATE USING THE SAME, AND LAMINATED OPTICAL MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a photocurable adhesive that exhibits coatable low viscosity in room temperature when pasting a protective film on a polarizer and has little effect on properties of the polarizing plate.SOLUTION: A photocurable adhesive provided herein is for pasting a transparent protective film on a polyvinyl alcohol polarizer, and contains 1-10 pts.wt. of a photo-cationic polymerization initiator (B) per 100 pts.wt. of a photo-cation curable component (A), the photo-cation curable component (A) containing 50-70 pts.wt. of an alicyclic diepoxy compound, 15-35 pts.wt. of an oxirane ring-containing epoxy cyclohexane compound, and 5-25 pts.wt. of a diglycidyl compound relative to the total amount thereof. The adhesive has a viscosity of no greater than 100 mPa sec at 25°C. A protective film is pasted onto a polarizer using the adhesive to produce a polarizing plate, and other optical layers are laminated thereon to produce a laminated optical member.SELECTED DRAWING: None
