Abstract

PURPOSE: To easily obtain multicolored stainless steel fit for mass production by forming an oxide film having an uneven thickness on the surface of stainless steel using ≥2 coating layers different from each other in acid resistance.
CONSTITUTION: On the surface of stainless steel ≥2 coating layers different from each other in acid resistance are formed by screen printing or other method using resins or resins and inorg. powder. The resin with higher acid resistance includes acrylic resin, and the resin with lower acid resistance includes cellulose resin such as cellulose acetate. The steel having the coated layers is dipped in a mixed soln. contg. 350W700g/l sulfuric acid and 200W400g/l chromic acid to form an oxide film having a partially uneven thickness on the steel surface. The residual coated layers on the steel surface are then removed by washing or other method to manufacture the desired multicolored stainless steel.
