Abstract
A reaction-injected foam molding comprising a skin coating film formed by the in-mold coating method and having an elongation at break of 20-200% (JIS K 6400: No. 1 dumb-bell test specimen) and a urethane foam body obtained by reaction injection molding and having a density of 0.35-0.60 g/cm3. Said molding permits easy removal of flashes even though the urethane foam body is of a high ratio expansion with a density of 0.35-0.60 g/cm3.
