PROBLEM TO BE SOLVED: To obtain the subject cured material excellent in water repellence, weather resistance, chemical resistance, stain resistance and adhesiveness, useful for a bathtub, etc., containing a siloxane part on the surface layer. SOLUTION: This cured material contains a siloxane part, preferably derived from (A) a silicon-containing macroazoinitiator and/or (B) a silicon-containing block copolymer. Preferably, the cured material is obtained by treating an unsaturated polyester resin with the components A and/or B. A compound of the formula (R is a lower alkyl; R is a lower alkyl or cyano; A1 and A2 are each an alkylene; R is a lower alkyl or phenyl; Y is NH or O; (m) is 0 or a natural number) is preferably used as the component A.
