Abstract:
A lignocellulosic material-containing composition comprising:an organopolyisocyanate which is a polyisocyanate composed chiefly of from 20% by weight to 70% by weight of a diphenylmethane diisocyanate having two benzene rings in one molecule and from 80% by weight to 30% by weight of a diphenylmethane diisocyanate polynuclear condensate having at least three benzene rings in one molecule, and has a viscosity of 500 mPaÂ·s or less in the state of solid content=100% by weight at 25Â° C.; a wax emulsion prepared by emulsifying a wax which is a paraffin wax containing at least 80% by weight of a paraffin having 20 to 40 carbon atoms, and has a melting point of from 40Â° C. to 100Â° C., with an emulsifier which is an ethylene oxide polyaddition product of an aliphatic monoalcohol whose aliphatic chain has 14 to 20 carbon atoms; and a lignocellulosic material.
