  • Publication number: 20130017375
    Abstract: A developing solution is disclosed with which it is possible to develop a photoresist disposed on a substrate including a conductive polymer. Also disclosed is a method for forming a resist pattern using the developing solution. The developing solution contains one or more acids and/or salts thereof, the acids being selected from inorganic acids, amino acids having an isoelectric point less than 7, and carboxylic acids having two or more carboxy groups. Use of this developing solution hence inhibits the phenomenon in which a substrate including a conductive polymer suffers an increase in surface resistivity due to a developing solution, and makes it possible to obtain a fine resist pattern.

  • Patent number: 4975357
    Abstract: Hydroxylamine compounds are commonly included in photographic color developing solutions to retard aerial oxidation. When the photographic element processed in the color developing solution is one which contains an aromatic polyhydroxy compound which serves as a stabilizing addendum, there will be a build-up of the level of such compound in the developing solution as seasoning occurs. Also, as a consequence of seasoning, there is a gradual build-up of the level of trace metal impurities in the solution. Interaction of a trace metal impurity with the aromatic polyhydroxy compound can form a metal-complex which catalyzes the oxidation of the hydroxylamine compound and thereby renders it ineffective for its intended purpose. In the improved method of this invention, the color developing solution is protected against the unwanted metal-complex catalyzed oxidation by incorporation therein of an aminopolycarboxylic acid sequestering agent.

  • Patent number: 4904576
    Abstract: Photosensitive cuprous halide-type materials, particularly cuprous chloride and cuprous bromide materials, can be prepared from an anode product material produced from electrolysis of copper in an aqueous acid halide bath. Preferably, the copper electrolysis is carried out in a dilute hydrochloric acid solution. The resulting anode product materials are particularly sensitive in the presence of a polar molecule catalyst such as water or ammonia. In one highly preferred embodiment of this invention the anode product material is treated with the aqueous solution of ammonium salt of a water soluble organic acid (e.g. aqueous solution of ammonium ascorbate); one of the chief advantages of these materials is that they are highly photosensitive when dry and can be developed from a latent image prepared thereon.
