MOLDING CONTAINING PHOTOCATALYST AND METHOD FOR MOLDING CONTAINING PHOTOCATALYST

摘要

PROBLEM TO BE SOLVED: To provide a new technique which can make the concentration of a photocatalyst in the surface part of a molding containing the photocatalyst higher than that in the inside of the molding without using a special device. SOLUTION: A resin composition containing the photocatalyst and a resin composition whose fluidity is lower than that of a resin constituting the photocatalyst-containing resin composition are melt-molded. The melt index of the resin constituting the former resin composition is preferably at least twice as large as that of the latter resin composition. COPYRIGHT: (C)2006,JPO&NCIPI
