| Abstract: |
| UV screen printing ink was prepared through formula design. The influence of prepolymer, photoinitiator,active diluent, and pigment on curing time, adhesion, flexibility and chemical resistance properties of the green UVcurable ink was studied. The result showed that the composite prepolymer system of polyester acrylate and polyurethane acrylate can give excellent performance to the UV-curable ink; the comprehensive performance of the ink is the best when the mass fraction of the prepolymer system is 51% , in which polyester acrylates and urethane acrylates mass ratio is 4 颐 1, Darocur1173 is 7% , the green pigment is 4% , and the active diluents HDDA is 33%. |
