ABSTRACT:
A process for producing a decorative sheet having the appearance of localized single or multi-colored patterns comprising: adding to a furnish of fibrous material in an aqueous dispersing medium about 0.1 to 25%, based on the weight of the fibers, of wax-encapsulated pigment beads containing numerous individual pigment particles of one or more colors, the beads having a particle size of about 0.1 to 2.0 millimeters; removing the aqueous dispersing medium from the furnish to form a fibrous sheet having the wax-encapsulated pigment beads dispersed therein; and heating the sheet to a temperature sufficient to at least partially melt the wax from the pigment beads, the pigment beads exhibiting random patterns of one or more distinct colors and intensity extending from the upper surface of the sheet to the bottom surface of the sheet; the decorative sheet formed by the method; and decorative laminates employing the decorative sheet are described.
