US 2003/0224173 A1 · Polymer-cellulose composites having increased fade resistance and process for producing same

Abstract

Excellent fade resistance and a substantial reduction in whitening can unexpectedly be achieved by adding colorant pigments to polymer-cellulose materials which form the polymer-wood composites, prior to formation of the composites. Then, the outer surface of the polymer-wood composites including the colorant pigments are distressed. The addition of the colorant pigments to the polymer-cellulose materials, combined with the distressing of the surface of the composites formed therefrom, results in an unexpected reduction in the unacceptable level of whitening and/or fading mentioned above which has not taken place in polymer-wood composites which include either a per se colorant pigment addition or which have been subject to a per se surface distressing operation.

Dependent claims

A polymer-cellulose composite having enhanced whitening reduction and/or fade resistance, which comprises:

a polymeric material;
a cellulose material;
and
a colorant pigment,
the composite having one or more outer surfaces which are substantially distressed, said substantially distressed outer surfaces having a substantially increased level of fade resistance than a comparable polymer-cellulose composite which does not have substantially distressed outer surfaces.
