Field of the Invention The present invention relates to an unsaturated polyester resin molded product having an unsaturated polyester resin on the surface thereof when manufacturing FRP bathtubs, washstands, table tops and toilet articles, and artificial marble products. More specifically, the present invention relates to a paint to be applied, that is, a gel coat composition, and more specifically to a resin composition for forming a gel coat film having antibacterial properties.

る保護層として機能する。The gel coat composition is a liquid thermosetting resin composition containing a pigment, an extender pigment, a thixotropic agent, a curing accelerator, etc. in an unsaturated polyester resin, a vinyl ester resin, or an acrylic syrup alone or in a mixture thereof. However, after adding a polymerization initiator to this and applying it to the mold surface by spraying or brushing, FRP and artificial marble are molded on it, or conversely, it is directly applied on the molded product for use. The FRP product functions as a protective layer against water, hot water, ultraviolet rays and the like, as well as imparting an aesthetic appearance such as gloss and coloring to the surface of the FRP product.
