Abstract
A photocurable compound prepared as a starting material by incorporation therein of a composition comprising a fluorescein compound photoreducing dye, tribenzylamine, and at least one specific peroxide permits production of a shaped article which, on exposure to visible light, exhibits high curability and acquires hardness virtually indiscriminately on the obverse and reverse sides of the article. A mixture comprising both or either of an unsaturated polyester resin and an epoxy acrylate resin which are photocurable compounds, glass fibers, and a specific peroxide, is convenient for the production of specific cured shaped articles particularly by the filament winding technique or the drawing technique.
