Abstract

An ink composition includes an acrylic resin including a polymerization product of a first monomer having a hydroxyl group, a second monomer having an epoxy group, a third monomer having an acrylate group, and a fourth monomer having a substituted or unsubstituted phenyl group, a first curing agent having an isocyanate group, and a second curing agent having an amine group. Durability and abrasion resistance of a window may be improved.

First claim

What is claimed is:

1. An ink composition, comprising:
an acrylic resin comprising a polymerization of product of a first monomer having a hydroxyl group, a second monomer having an epoxy group, a third monomer having an acrylate group, and a fourth monomer having a substituted or unsubstituted phenyl group;
a first curing agent having an isocyanate group; and
a second curing agent having an amine group.

2. The ink composition of claim 1 , further comprising an epoxy resin.

3. The ink composition of claim 1 , wherein the first monomer is hydroxypropyl acrylate.

4. The ink composition of claim 1 , wherein the second monomer is glycidyl methacrylate, glycidyl acrylate, allyl glycidyl ether, or a combination thereof.

5. The ink composition of claim 1 , wherein the third monomer is methyl methacrylate.

6. The ink composition of claim 1 , wherein the fourth monomer is benzyl methacrylate, styrene, t-butyl styrene, or a combination thereof.

7. The ink composition of claim 1 , comprising, based on 100 moles of the acrylic resin,
from about 10 moles to about 30 moles of the first monomer;
from about 10 moles to about 20 moles of the second monomer;
from about 20 moles to about 35 moles of the third monomer; and
from about 20 moles to about 35 moles of the fourth monomer.

8. The ink composition of claim 1 , wherein the acrylic resin is represented by the following Formula 1:

in Formula 1,
“a”, “c”, and “d” are each independently an integer of 1 to 3,
“b” is 1 or 2,
X is

R 1 and R 2 are each independently hydrogen or a methyl group, and
“n” is an integer of 200 to 400.

9. The ink composition of claim 1 , wherein the acrylic resin is a polymer resin having a weight average molecular weight of from about 20,000 grams/mole to about 40,000 grams/mole.

10. The ink composition of claim 1 , wherein
the first curing agent comprises two or more isocyanate groups, and
the second curing agent comprises two or more amine groups.
