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.
