<p>PURPOSE:To provide an org. noble metal ink suitable for use in ornament etc. and capable of giving an even smooth coating surface, by combining a noble metal salt of resinic acid with a binder resin selected from alkyd, urea and melamine resins, and a solvent. CONSTITUTION:At least one noble metal salt of resinic acid (A) (e.g., gold resinate or platinum resinate) is mixed with at least one binder resin (B) selected from alkyd, urea and melamine resins, and a solvent (C) (e.g., terpene alcohol) as indispensable components to prepare the desired org. noble metal ink. The use of the component B capable of serving as a binder even in a smaller amt. than that of conventional binders enables the amt. of the binder to be decreased to thereby prevent formation of aggregates on the surface of a baked ink coating film caused by the binder, formation of pinholes therein caused by escape therethough of a gas, etc.</p> |
