(57) [Summary] [Structure] A gel base material mainly comprising an oligomer and a monomer having a photocurable unsaturated bond, a fragrance, a dye, and an ultraviolet absorber composed of a benzophenone derivative or a benzotriazole derivative. Against 0.001 ~ 2.0% by weight and 0.001 of a light stabilizer consisting of a 2,2,6,6-tetramethylpiperidine compound to the gel substrate. ˜2.0% by weight. [Effect] It is stable against light and does not fade due to irradiation of light energy during curing or exposure to light during use. |
