CAST-COATED PAPER

摘要

A cast-coated paper which is excellent in coated-paper quality and printability and functions to decompose a harmful substance upon irradiation with light. The cast-coated paper is obtained by forming on a raw paper a cast coating layer comprising a pigment and an adhesive as major components and pressing the cast coating layer in a wet state against a heated mirror surface of a drum to dry and finish the layer. The cast-coated paper is characterized in that the cast coating layer contains titanium oxide having an average secondary-particle diameter of 300-2,000 nm in an amount of 1-30 parts by weight per 100 parts by weight of the pigment and the titanium oxide has been treated beforehand by mixing it with a silica sol or alumina sol in a [titanium oxide]/[silica sol or alumina sol] proportion of from 2/1 to 1/2.
