(57) [Summary] [Structure] (A) An unsaturated polyester obtained by reacting an acid component and an alcohol component, (B) a crosslinkable monomer, (C) a vanadium compound, (D) an alkyl phosphate and (E) ) An unsaturated polyester composition containing a quaternary ammonium salt, a method for producing a cured product of the composition, and a molding material using the composition. [Effect] The rapid curability and the light-color transparency of the hue of the cured product are maintained, and the change with time in the room temperature gelation time can be reduced. |
