PRODUCTION OF BASE MATERIAL HAVING CRACK-PATTERNED SURFACE

摘要

PURPOSE:To obtain easily a base material having a desired crack-patterned surface, by forming a curable resin on the surface of the base material, heating the same to a half cured state, and bringing the layer into contact with an org. solvent then curing thoroughly the resin. CONSTITUTION:A curable resin layer of melamine, acrylic or the like is formed on the surface of a base material of a plastic, metal, etc. Such resin layer is cured to a half cured state by heating or the like, and an org. solvent such as ketones or the like is brought into contact with the surface thereof by a suitable means to generate cracks. The resin layer is then subjected to a heat treatment or the like and is thus thoroughly cured. Otherwise, a resist layer is partially provided on the resin layer prior to contact with the org. solvent and cracks are generated in desired parts.
