PROBLEM TO BE SOLVED: To provide a plastic substrate for an automotive glazing excellent in transparency, hardness, adhesion and weatherability.SOLUTION: In a resin coating product, a plastic substrate body has three or more resin layers on its surface, the first layer contacting with the surface of the substrate body out of these resin layers is a cured resin layer of a coating agent not containing a curing catalyst and containing a vinyl-system copolymer having an alkoxysilyl group and an ultraviolet ray absorbing group, and silicon oxide fine particles, the second layer contacting with the first layer is a cured resin layer of an organopolysiloxane composition containing a curing catalyst and a cohydrolyzate of an organosilicon compound containing an ultraviolet ray absorbing organooxysilane and silicon oxide fine particles, and the third layer contacting with the second layer is a cured resin layer of an organopolysiloxane composition containing a curing catalyst having an activity stronger than the catalyst used in the second layer, and a cohydrolyzate of an organosilicon compound containing an ultraviolet ray absorbing organooxysilane and silicon oxide fine particles. |
