Abstract: A DECORATED MULTIPLE LAYER PAPER SUITABLE FOR USE AS A TOP SURFACE IN RESIN IMPREGNATED ABRASION RESISTANCE DECORATED LAMINATES, AND THE LAMINATES PREPARED THEREFROM, SAID MULTIPLE LAYER HAVING A BASE LAYER AND A TOP LAYER, THE TOP LAYER COMPRISING ABRASION RESISTING MINERAL PARTICLES HAVING A HARDNESS OF 7 OR MORE ON THE MOH SCALE AND A PARTICLES SIZE RANGING FROM 10 TO 75 MICRONS, AND WITH A PRINTED PATTERN OVER THE EXPOSED SURFACE OF THE TOP LAYER. THE MULTIPLE LAYER PAPER IS MADE BY DEPOSITING A

BASE LAYER ON A PAPER MACHINE FORMING WIRE, AND WHILE THE BASE LAYER IS IN A WET STATE AND STILL SUPPORTED ON THE FORMING WIRE, DEPOSITING THE TOP LAYER THEREOVER. ABRASION RESISTANT DECORATIVE LAMINATES ARE PREAPPARED FROM SAID DECORATED MULTIPLE LAYER PAPER BY SATURATING SAID PAPER WITH A RESIN, SUITABLY A THERMOSETTING RESIN FOLLOWED BY UNITING WITH A CORE AND CURING OF SAID RESIN.

Abstract: A TITANIUM DIOXIDE FILLED PAPER WITH AN ADDED CRYSTALLINE COLLOID FOR IMPROVED LIGHT SCATTERING EFFICIENCY. THE CRYSTALLINE COLLOIDAL MATERIAL IS SELECTED FROM THE CLASS CONSISTING OF HYDROUS ALUMINUM OXIDE AND HYDROUS MAGNESIUM SILICATE HAVING AN AVERAGE VOLUME EQUIVALENT TO A SPHERE WITH A DIAMETER RANGING BETWEEN ABOUT 10-30 MILLIMICRONS. THE IMPROVED SCATTERING EFFICIENCY INCREASES THE OPACITY OF THE SHEET AND MAKES IT ESPECIALLY ADAPTED FOR USE AS A PRINT SHEET IN A DECORATIVE PLASTIC LAMINATE.
