The white, red and black UV paints were prepared by with epoxidized soybean oil acrylate resins as its main resin and the titanium dioxide, iron oxide red or carbon as its pigment respectively. The influences of kinds of photoinitiators,their compounding on the curing effect,hardness and adhension of the final coating films were studied. The results indicate that Irgacure 184 with respect to the mass ratio of 1 : 2 Irgacure 819 triggered effect is best in the white system and Irgacure 184 and Irgacure 907 mass ratio of 1 : 2 have a high initiator in the red system, Irgacure 184 and Irgacure 907 and ITX is 1 : 4 : 1 which is the best initiator composition in the black system.
