摘要： A process is provided for producing a compression molded article of a lignocellulose type material by use of an organic polyisocyanate compound as a binder. The process comprises carrying out adhesion by use of the following components (A) an organic polyisocyanate, (B) an aqueous emulsion of a wax having a melting point ranging from 50.degree. C. to 160.degree. C., and (C) an organic phosphate ester derivative and optionally (D) water. The compression molded article can readily be released from the mold, and has excellent physical properties.
