ABSTRACT:
A wear-resistant wood product such as a wood flooring material having a white or bleached appearance which is obtained by impregnating wood with a solution of a polymeric resin whitening agent in a polymerizable monomer such as methylmethacrylate and, after uniform distribution of the monomer solution throughout the wood is obtained, the monomer is polymerized and the whitening agent precipitated in situ in the polymer matrix as a material having a refractive index sufficiently different from the refractive index of said matrix to impart a bleached or white appearance to said product.
