    摘要: Disclosed are shaped articles having a coating layer formed on surface region, wherein the surface region is formed of a polymer derived from a multifunctional acrylic monomer and having 0.02 to 0.2 .mu.mol/cm.sup.2 of acidic groups therein, by curing a coating composition consisting essentially of a specific silica polycondensate. The silica polycondensate is obtained by mixing (I) colloidal silica and (II) a specific silicon compound in such a molar ratio that the average number of hydrolyzable groups is within the range of 2.30 to 3.85, and then subjecting them to cohydrolysis and polycondensation. In these shaped articles, the coating layer have excellent properties such as hardness and abrasion resistance, as well as good adhesion.

    摘要: A method of forming a corrosion resistant film for a specified image on the surface of a substrate by adding an aliphatic amine such as ethylenediamine, monoethanolamine, diethanolamine triethanolamine to a sensitizing solution composed of water-soluble high molecular compound and ammonium dichromate so as to adjust pH value of the sensitizing solution in the range of 6.1 to 7.8, applying the prepared sensitizing solution to the surface of a substrate of copper or copper alloy, and undergoing each process of drying, exposure and development. After an etching process being applied to the substrate on the surface of which the corrosion resistant film has been formed, the corrosion resistant film is removed to be a finished goods.
