PURPOSE: To obtain braille printed matter which permits easy tactile reading and has a sufficient height without entailing fatigue even in long-term tactile reading by successively providing the surface of a base material with a printed layer and build-up layers consisting of foamed resin layers and non-foamed resin layers.
CONSTITUTION: The printed layer 2 of braille characters and picture pattern is formed by a method, such as planographic printing or letterpress printing on the base material 1. The surface thereof is then provided with the build-up layers 5 consisting of the foamed resin layers 3 and the non-foamed resin layers 4. The foamed resin layers 3 are formed by using microcapsule particle powders formed by enclosing compsns. of an azo system, sulfonyl hydrazide, etc., decomposable to a gaseous form by heating with film forming materials, such as gelatin, and subjecting these powders to foaming under heating. The nonfoamed resin layers 4 are formed by subjecting thermoplastic resin powders used from heretofore, in a foam printing method, for example, resin powders of a vinyl chloride-vinyl acetate copolymer, polyamide resin, etc., to melting under heating. The compounding ratio of both is 10 to 50 pts.wt. microcapsule particle powders per 100 pts.wt. thermoplastic resin powders.
