ALKALI-SOLUBLE PHOTOCURABLE COMPOSITION, CURED COATING FILM USING THE COMPOSITION AND TRANSPARENT MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a photocurable composition which can be developed with an aqueous alkali solution and forms a coating film having a low water absorbing property, high hardness and excellent adhesion to a substrate of glass, a metal oxide, a metal or the like as a composition applicable to a transparent member desired in a field of a display device such as a liquid crystal display or a touch panel or in the field of an organic TFT.

SOLUTION: The photocurable composition includes: (A) an alkali-soluble resin which is a (meth)acrylate copolymer having a carboxyl group and an ethylenically unsaturated group within a molecule; (B) silica fine particles; (C) a reactive monomer having one or more (meth)acryloyl groups within a single molecule and including (C1) a (meth)acrylate compound having a fluorene skeleton and (C2) a (meth)acrylate compound having an alkoxysilane moiety; and (D) a photopolymerization initiator.
