Abstract: PURPOSE:To improve the corrosion resistance of a colored stainless steel and to prevent the deterioration of appearance by corrosion without discoloration in corrosive environment by forming an org.-inorg. composite resin film consisting of the specific compsn. formable at a low temp. on the surface of said stainless steel. CONSTITUTION:A colored film having much color change according to various thicknesses is formed on the stainless steel by treating the stainless steel with an aq. soln. mixture composed of CrO3 and H2SO4. The colored film is highly resistant to wear but has the easy tendency to rust formation as the effect of protecting the surface in the corrosive environment is not enough. The org.- inorg. composite resin film consisting first of a water soluble or water dispersible org. polymer resin such as acrylic copolymer, alkyd resin or epoxy resin and next of water dispersible silica such as colloidal silica and reactive silane such as silane coupling agent or reactive Ti compd. is formed at a low temp. of about 150 deg.C on the surface of such film in order to overcome the above- mentioned defect.
