Abstract
Disclosed herein are a composition for forming a hard coating layer that is easy to mold, a hard coating layer including the composition, and a laminate including the hard coating layer. The composition may include a hard coating resin, a photoinitiator, a thermal initiator, and a solvent, where the weight ratio of the photoinitiator to the thermal initiator ranges from 1:50 to 10:1.
Claims13
A composition for forming a hard coating layer, comprising:
- a hard coating resin, wherein the hard coating resin comprises at least one resin selected from the group consisting of silsesquioxane, 1H,1H,2H,2H-heptadecafluorodecyl acrylate, and 2-hydroxyethyl methacrylate;
- a photoinitiator;
- a thermal initiator;
- and
- a solvent,
- wherein the photoinitiator is contained in an amount of 0.1 to 1 wt. % with respect to the total weight of the composition, and the thermal initiator is contained in an amount of 0.1 to 5 wt. % with respect to the total weight of the composition, and
- wherein the amount of the photoinitiator and the amount of the thermal initiator are selected to achieve three-dimensional moldability and satisfy a condition that a weight ratio of the photoinitiator to the thermal initiator is in a range from 1:2 to 1:10.
