LIGHT CURABLE HARD COATING RESIN COMPOSITIONS WITH HIGH WEATHER RESISTANCE AND LIGHT CURING METHOD OF THE COMPOSITION

摘要

A light-curable hard coating resin composition having high weather resistance is provided to increase weather resistance of a light-curable coating layer even when a light stabilizer is added, and to improve a curing rate and curing properties. A light-curable hard coating resin composition having high weather resistance includes 30-60wt% of a prepolymer having at least one acrylic group, 30-60wt% of an acrylic monomer or vinylether monomer having at least one acrylic group, 0.1-10wt% of at least two free radical-based photoinitiators having an absorption region of 300-400 nm wavelength, and 0.1-2wt% of a light stabilizer mixture of hindered amine light stabilizers.
