Abstract

Official abstract text for this publication.

A method of manufacturing an ink blocking layer for a display device, an ink blocking layer for a display device, and a display device are provided. The method of manufacturing an ink blocking layer for a display device includes: preparing a main material including an epoxy monomer having three or more epoxy groups and a curing agent including an acid and an amine; and mixing the main material with the curing agent to prepare an epoxy resin.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of manufacturing an ink blocking layer for a display device, the method comprising: preparing a main material comprising an epoxy monomer having three or more epoxy groups and a curing agent comprising an acid and an amine; and mixing the main material with the curing agent to prepare an epoxy resin, wherein the epoxy monomer has an epoxy equivalent of 95 to 110 g/eq, wherein the acid comprises an acrylic acid resin, and wherein the epoxy resin comprises an unreacted acrylic acid resin and/or an unreacted amine. 2. The method of claim 1 , wherein the epoxy monomer is produced by a reaction of a polyhydric alcohol and epichlorohydrin. 3. The method of claim 2 , wherein the polyhydric alcohol is a trihydric or higher alcohol. 4. The method of claim 3 , wherein the polyhydric alcohol is a heptahydric or higher alcohol produced by a reaction of a hexahydric or lower alcohol and isocyanate. 5. The method of claim 1 , wherein the acid comprises a carboxyl group (—COOH). 6. The method of claim 1 , wherein the acid has an acid value of 5 to 15. 7. The method of claim 1 , wherein the amine is included in the curing agent in an amount of more than 0 wt % and less than 20 wt % with respect to a total amount of the acid. 8. The method of claim 1 , wherein the mixing of the main material with the curing agent is performed at 100° C. to 160° C. 9. The method of claim 1 , wherein the mixing of the main material with the curing agent is performed for 5 to 30 minutes. 10. The method of claim 1 , wherein the amine comprises at least one selected from the group consisting of triethylenetetramine (TETA), diethylenetriamine (DETA), and ethylenediamine (EDA).
