3D Curable resin composition for 3D printing with good developing properties and contraction percentage comprising cycloaliphatic epoxy acrylic compound having cation curing and UV curing mechanizm

摘要

The present invention relates to a resin composition for three-dimensional (3D) printing, ensuring excellent developability and shrinkage rate, including a novel alicyclic epoxyacrylic compound, and having cationic curing and ultraviolet curing mechanisms. More specifically, the present invention relates to a resin composition for 3D printing, ensuring excellent developability and shrinkage rate, including a novel alicyclic epoxyacrylic compound, and having cationic curing and ultraviolet curing mechanisms. To this end, an epoxy group and an acryl group are present at the same time in a structure of the compound, and radical-type curing and cation-type curing by ultraviolet irradiation simultaneously take place.
