ABSTRACT:
Disclosed is a composition for formation of a cured resin foam, which comprises (A) a curable resin composition comprising an unsaturated polyester prepolymer and an ethylenically unsaturated monomer, (B) an inorganic powder composed of a carbonate and/or bicarbonate, (C) an aqueous solution of a water-soluble inorganic compound containing a neutralizable acid radical and being capable of forming a colloidal oxide or hydroxide and being gelled by neutralization or an acidic aqueous sol of an inorganic oxide or hydroxide containing a neutralizable acid radical and being capable of being gelled by neutralization, and (D) a substantially water-insoluble surface active agent having a W/O type emulsion-forming capacity, wherein an emulsion structure having a continuous phase of the component (A) and a dispersed particle phase of the component (C) is formed.
