PRODUCTION METHOD FOR PATTERNED PHOSPHORESCENT BODY, PATTERNED PHOSPHORESCENT BODY, AND EVACUATION GUIDE SIGN

摘要

Provided are: a production method for a patterned phosphorescent body capable of producing a patterned phosphorescent body with excellent light emission (phosphorescent) performance through simple and easy production processes; a patterned phosphorescent body, and an evacuation guide sign. A mixture obtained by mixing at least a phosphorescent material and a glass material is filled in a mold and the mixture is press-molded so as to provide a planar part (10), thereby to create a molded body. The molded body is baked and slowly cooled, and then transfer paper of a water transfer type is attached to a surface of the planar part (10) of the baked molded body (4) and re-baking is performed at a temperature lower than a baking temperature of the molded body to impress a pattern (11) on the transfer paper.
