Abstract
The present invention relates to a hard coating film, and more particularly, to a hard coating film that includes a high elongation oligomer having an elastic modulus and elongation at break in a specific range on a transparent substrate, and thus can exhibit excellent impact resistance and bending resistance and can minimize the occurrence of a curl caused by cure shrinkage of a hard coating film, and an image display device using the same.
Claims5
A hard coating film formed on a transparent substrate and consisting of one hard coating layer, wherein the hard coating layer comprises a cured product of a hard coating composition including a high elongation oligomer having an elastic modulus ranging from 10 to 3000 MPa and an elongation at break ranging from 30 to 150%, wherein the high elongation oligomer comprises urethane (meth)acrylate, wherein polymers in the cured product of a hard coating composition are homopolymers of the high elongation oligomer, wherein the cured product of the hard coating composition has a thickness ranging from 50 to 300 μm.
