Abstract
Provided are a phenoxy resin composition for transparent plastic substrate and a transparent plastic substrate using the phenoxy resin composition, capable of effectively substituting for a conventional glass substrate since having excellent thermal and chemical resistance, high adhesiveness, low water infiltration, and a small coefficient of linear thermal expansion. In one general aspect, there is provided a phenoxy resin composition for transparent plastic substrate, including: phenoxy resin having a chemical structure expressed as follows: wherein the n value is 35 to 400.
Claims6
A method for preparing a transparent substrate for flexible display, comprising:
- preparing a phenoxy resin composition comprising phenoxy resin of Formula (I):
- wherein n value is from 35 to 400, inclusive,
- wherein an end of the phenoxy resin comprises one or more groups selected from the group consisting of an epoxy group, a hydroxyl group, an amine group, a fluorine group, a siloxane group, and an amide group,
- an energy-ray curable acrylic oligomer or acrylic polymer resin,
- a photoinitiator selected from the group consisting of benzophenone, acetophenone, dibenzyl, diacetyl, diphenyl sulfide, azobisisobutyronitrile and a mixture thereof, and
- a crosslinking agent selected from the group consisting of melamine, urea-formaldehyde, isocyanate functional prepolymer, a phenolic curing agent, an amino-group curing agent, and a mixture thereof;
- forming on a release film the phenoxy resin composition into a film or sheet having a thickness of from about 25 to about 1,000 microns by a solvent casting or melt extrusion method, wherein the film or sheet is used to fabricate a flexible plastic substrate capable of substituting for a glass substrate used in an optical device substrate or a Flat Panel Display (FPD) substrate, a color filter substrate, or a substrate for touch screen panel;
- curing the phenoxy resin composition by ultraviolet light;
- and
- removing the release film.
