(b) the photoinitiator-g-C obtained in the step (1)3N4And (3) uniformly mixing the acrylic monomer premix, hydroquinone monomethyl ether and a second auxiliary agent, reacting at 30-40 ℃ under the irradiation of visible light, and filtering to obtain a second coating resin.
7. Use according to claim 1, wherein the oxygen content is controlled to be less than 1000ppm during photocuring.
