Method of patterning molded article surface

摘要

A method of patterning the surface of a molded article obtained by pressure-molding a powdery inorganic binder material which comprises vibrating the powdery inorganic binder material to thereby smoothen the surface thereof, then disposing a colored material having a different color from the inorganic binder material on the surface of the inorganic binder material and then pressure-molding the inorganic binder material together with the colored material to thereby form a pattern on the surface of the molded article. Thus, a pattern can be conveniently and economically formed on the surface of a molded article.
