Embodiment 1

[0158] Example 1, Example 2, Comparative Example 1, and Comparative Example 2 are examples and comparative examples for determining the ratio of the crosslinking agent. When the addition ratio of the crosslinking agent is based on the overall weight of the monomer, when it is less than 20wt%, the number of alcohol rubbings decreases, the crosslinking density of the polymer resin decreases and the chemical resistance decreases, and when it exceeds 25wt%, Shows the characteristic of light transmittance reduction.

Embodiment 3

[0159] Example 3 and Comparative Example 3 to Comparative Example 6 are examples and comparative examples for determining the ratio of monomers. Example 3 showed excellent results in the transmittance evaluation, alcohol rubbing evaluation, and cross-cut evaluation. Referring to Comparative Example 3 and Comparative Example 4, when the second monomer and the third monomer were mixed in a ratio of 80 mol %, the cross-cutting property was lowered, and the hardness was too high to exhibit low durability. Referring to Comparative Example 6, when butyl acrylate was added instead of the second monomer, the number of rubbings with alcohol was reduced, showing a characteristic of reduced chemical resistance. That is, when referring to Comparative Example 6, it can be seen that it is not simply lowering T g As far as the polymer resin shows good properties, it needs to contain a certain amount of the second monomer.

[0160] Referring to Comparative Example 5, it showed excellent res...

Abstract

The invention relates to a polymer resin, a window module comprising the polymer resin and a display device comprising the window module. According to one embodiment of the invention, the window module comprises a window, a first print layer, an ink layer, and a protective layer covering the ink layer. The ink layer includes a polymer resin polymerized from monomers including a first monomer whichis an acrylic monomer substituted with a hydroxy group, a second monomer having an epoxy group, and at least one of a third monomer having a substituted or unsubstituted phenyl group or a fourth monomer which is an acrylic monomer having a substituted or unsubstituted bicyclic alkyl group, and thus, has excellent durability, chemical resistance, and abrasion resistance.

Description

technical field [0001] The present disclosure relates to a polymer resin, a window module including the same, and a display device including the window module. More specifically, it relates to a polymer resin having improved chemical resistance and abrasion resistance, a window module including the same, and a display device including the window module. Background technique [0002] When defects occur in the manufacturing process of the display device, a rework process is required in order to save costs. In the rework process, in order to bond the window module and the display panel, it may include a process of removing the adhesive layer disposed on the window module, for which physical or chemical treatment may be performed on the surface of the window module. In this case, problems such as damage or staining of the ink printed on the window module arise. Contents of the invention [0003] An object of the present disclosure is to provide a polymer resin with improved ...
