LUMINESCENT PRODUCT AND PROCESS FOR PRODUCING THE SAME

Document Type and Number:

WIPO Patent Application WO/2008/018210

Kind Code:

A1

Abstract:

A luminescent product molded by centrifugal molding which is inhibited from curling and has a white layer for improving phosphorescent performance. The product comprises: a hiding layer formed from a first mixture which is a mixture of a first thermosetting resin and a pigment by subjecting the mixture to centrifugal molding with heating; a phosphorescent layer obtained from a second mixture which is a mixture of a second thermosetting resin and a phosphorescent pigment having a higher specific gravity than the second thermosetting resin by pouring the second mixture on the hiding layer and subjecting it to centrifugal molding with heating; and a transparent layer. The phosphorescent layer is located nearly at the center of the product thickness. Thus, the product can be effectively inhibited from curling.
