PIGMENT MIXTURE COMPRISING KAOLIN AND TITANIA FOR USE IN PAPER-MAKING

摘要

A heated mixture comprising dehydroxylated kaolin and a high refractive index pigment is disclosed. When the dehydroxylated kaolin is metakaolin, the heated mixture has a GE brightness greater than 86% and a Hunter yellowness index of less than about 11. When the dehydroxylated kaolin is fully calcined kaolin, the heated mixture has a GE brightness greater than 89%. The heated mixture is advantageously used in decorative paper. Also disclosed are methods of using and making the decorative paper, and decorative laminates containing the decorative paper.
