Patent ID: 7868117

Claim:
A method of producing a liquid resin composition for a hard coat, comprising a first step of copolymerizing a tri-functional or higher (meth)acrylic monomer, or oligomer or polymer thereof with a monomer having an alkoxysilyl group, using a polymerization initator, to obtain a tri-functional or higher (meth)acrylate having an alkoxysilyl group, in which the monomer having an alkoxysilyl group is selected from the group consisting of 3-methacryloxypropylmethyldimethoxysilane, 3-methacryloxypropyltrimethoxysilane, 3-methacryloxypropylmethyldiethoxysilane, 3-methacryloxypropyltriethoxysilane, vinyltriethoxysilane, vinyltrimethoxysilane, p-styryltrimethoxysilane, 3-acryloxypropyltriethoxysilane, and vinyltriacetoxysilane; a second step of condensating the tri-functional or higher (meth)acrylate having an alkoxysilyl group as obtained in the first step and a metal oxide fine particle having a hydroxyl group on a surface thereof; and a third step of adding a photopolymerization initiator to a solution in which the tri-functional or higher (meth)acrylate having the alkoxysilyl group and the metal oxide find particle having the hydroxyl group on the surface thereof bind by a condensation reaction.
