New acrylates synthesized from plant-derived raw materials such as glycerin and sorbitol were evaluated as UVcurable resins. Glycerin triacrylate (GTA) has the features of low viscosity, high hardness and high adhesion as compared with conventional trifunctional or higher functional acrylates. Glycerin carbonate acrylate (GCA), which is an acrylate of glycerin carbonate synthesized from glycerin and carbonic acid ester, has the features of high UV curability, high Tg and low water absorption rate as compared with conventional monofunctional acrylates. Ethoxylated sorbitol acrylate has the features of high water solubility, UV curability, high hardness, and water dilution as compared with conventional hydrophilic acrylates. The biomass degree of GTA and GCA are as high as 35% and 50%, respectively. They are expected to be applied to inks, paints, adhesives, etc. as photo-curing resins with low environmental load.
