Abstract
Anti-glare film including anti-glare layer. The anti-glare film is obtained by coating or casting a liquid compositions containing a polymer, a curable resin precursor, and a solvent on a transparent plastic film, evaporating the solvent, forming a phase separation structure by spinodal decomposition, and curing the curable resin precursor by irradiation with light. The disclosed anti-glare film prevents reflection of surrounding scenery and dazzle in a display surface.
Claims5
A composition for an anti-glare film which comprises a plurality of polymers and at least one curable resin precursor,
- wherein the plurality of polymers are phase-separable by spinodal decomposition from a liquid phase and at least one curable resin precursor is compatible with at least one polymer of the plurality of polymers,
- wherein the at least one curable resin precursor comprises at least one member selected from the group consisting of an epoxy (meth)acrylate, a urethane (meth)acrylate, a polyester (meth)acrylate, a silicone (meth)acrylate, and a polyfunctional monomer having at least two polymerizable unsaturated bonds, and
- wherein the phase-separable plurality of polymers comprises a cellulose derivative and at least one resin selected from the group consisting of a styrenic resin, a (meth)acrylic resin, an alicyclic olefinic resin, a polycarbonate-series resin, and a polyester-series resin, and at least one polymer of the plurality of polymers has a (meth)acryloyl group.
A process for producing an anti-glare film comprising at least an anti-glare layer, which comprises forming a phase separation structure by spinodal decomposition from a liquid phase with evaporating a solvent, curing the resin precursor to form the anti-glare layer, and the liquid phase contains at least one polymer, at least one curable resin precursor, and the solvent.
