Title: Pretreating method for etching
Inventor: TAKEUCHI TAKESHI
IPC: C23F1/00
Filed: 1979-03-16
Abstract: PURPOSE: To make a sharp and deep-bored etching pattern, by, prior to etcing of steel material, immersing the steel material in an oxidizing soln. to form an oxide coating on the surface, then by forming resist ink coating on the surface by a prescribed method.  
     CONSTITUTION: Prior to the etching with chemicals, plain steel material 2 or iron base alloy, e.g., stainless steel, is immersed in a mixed soln. of chromic acid and sulfuric acid to form oxide coating 6 (alkaline oxidizing or acidic oxidizing method may be used). The thickness of the oxide coating 6 may pref. be controlled by a method known to public, i.e., by monitoring the potential difference developed between a reference electrode and the steel material surface to be colored through immersion of the material in an oxidizing soln. Then a resist ink coating 1 of prescribed pattern is formed on the oxide coating 6 by a prescribed method, e.g., photoprinting, screen printing etc., thereby conducting pretreatment. Hereby, dissolution due to corrosion during etching at the boundary 3 is prevented by the formation of oxide coating 4 to form a sharp etched concave surface.

Title: Seal forgery preventing method utilizing heat-sensitive ink
Inventor: SHIOYAMA EISUKE
IPC: B41M5/30
Filed: 1980-03-13
Abstract: PURPOSE:To prevent the forgery of a seal by a method wherein the sealed surface is coated with an ink containing one of two components and covered with a transparent film containing an ultraviolet absorbing agent so that the seal impression cannot be readily read. CONSTITUTION:On a print 2, a seal is stamped to form a seal impression 3 by using, instead of the vermilion ink, an ink containing the A material in a two-part liquid reaction type heat-sensitive color former. Subsequently, a cover 5, which is made of transparent film containing an ultraviolet absorbing agent and whose one surface is coated with an ink 4 containing the B material in the heat-sensitive color former, is attached to the sealed surface by using an adhesive gluing agent 6 so that the coating layer 4 surface is on the sealed surface side. The adhesive gluing agent 6 is applied to the periphery of the cover 5 so that the coating layer 4 is brought into contact with the sealed surface directly. After the cover 5 has been provided, if black light is applied, ultraviolet rays are absorbed, so that the portion of the ink 2 will not fluoresce. Therefore, there is no difference between the luminances of the reflected rays from the portions of the ink 2 and the ink 3, so that it is completely impossible to read the seal impression.
