Title:
ACTIVE ENERGY RAY-CURABLE RESIN COMPOSITION FOR FILM PROTECTION LAYER, FILM USING SAME AND OPTICAL SHEET
Document Type and Number:
WIPO Patent Application WO/2007/043570
Kind Code:
A1
Abstract:
Disclosed is an active energy ray-curable resin composition for film protection layers which produces only small curling when applied over a base such as film or sheet and cured thereon by being irradiated with an active energy ray such as ultraviolet light. This active energy ray-curable resin composition enables to obtain a cured film having high hardness and high abrasion resistance, which does not suffer from chipping or cracking during cutting. Also disclosed is a film having a protective layer composed of a cured film of such an active energy ray-curable resin composition, and an optical sheet composed of a cured product of such an active energy ray-curable resin composition. Specifically disclosed is an energy ray-curable resin composition for film protection layers which is characterized by containing a urethane acrylate (A) as an addition reaction product of a norbornane diisocyanate (a-1) and at least one acrylate (a-2) having a hydroxyl group which is selected from the group consisting of pentaerythritoltri(meth)acrylate, dipentaerythritolpenta(meth)acrylate and bis(2-(meth)acryloyloxyethyl)hydroxyethyl isocyanurate, a multifunctional acrylate (B) having three or more (meth)acryloyl groups in a molecule, and/or a polymer (C) having a (meth)acryloyl group obtained by reacting a glycidyl(meth)acrylate polymer having an epoxy group in a side chain with an α,β-unsaturated carboxylic acid.
