Title:
ADHESIVE AGENT COMPOSITION FOR OPTICAL FILMS, ADHESIVE AGENT LAYER FOR OPTICAL FILMS, OPTICAL FILM HAVING ADHESIVE AGENT LAYER ATTACHED THERETO, AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/152201
Kind Code:
A1
Abstract:
An adhesive agent composition for optical films, which comprises: a (meth)acrylic polymer (A) that contains, as monomer units, 70% by weight or more of an alkyl (meth)acrylate (a1), 3 to 25% by weight of an aromatic-ring-containing (meth)acrylate (a2), 0.1 to 8% by weight of an amide-group-containing monomer (a3), 0.01 to 2% by weight of a carboxyl-group-containing monomer (a4) and 0.01 to 3% by weight of a hydroxyl-group-containing monomer (a5) and meets such requirements that the weight average molecular weight (Mw) is 1,000,000 to 2,500,000 and the Mw/(number average molecular weight (Mn)) ratio is 1.8 to 10 inclusive; and a cross-linking agent (B) in an amount of 0.01 to 3 parts by weight relative to 100 parts by weight of the (meth)acrylic polymer (A). The adhesive agent composition can be formed into an adhesive agent layer which satisfies durability to such an extent that the adhesive agent layer does not undergo foaming, is not detached or does not get clouded under humidified conditions when applied onto a glass or a transparent conductive layer, and which can prevent the occurrence of display unevenness due to leakage of light, and which has excellent metal corrosion resistance.
