| abstract |
The present invention relates to a novel 2,4,6-triaminotriazine-based urethane acrylate compound and a preparation method therefor and, more specifically, to a novel 2,4,6-triaminotriazine-based urethane acrylate compound having superior hardness, heat resistance and flexural strength over those of a conventional 2,4,6-triaminotriazine methacrylate, and usable in a radiation curable composition for high definition 3D printing by having a 2,4,6-triaminotriazine-based urethane acrylate backbone structure obtained from a urethane reaction of methacrylate, having an isocyanate group (-NCO), with a 2,4,6-triaminotriazine mother nucleus. |
