    摘要: According to the invention there is provided an electrochemical process for applying a firmly bonded insoluble metal oxide-organic complex on a metal surface by employing the metal as anode and a water-soluble poly basic organic acid as electrolyte together with a strong inorganic acid such as phosphoric acid or further admixed with another strong inorganic acid such as sulfuric. The polybasic acid may be a polyphosphonic acid, polyphosphoric and polycarboxyl acid, or polysulfonic acid and is advantageously polymeric. Polyvinyl phosphonic acid (PVPA) is a preferred electrolyte. Direct current is used. Pulsed plating may optionally be employed. The insoluble metal oxide-organic complex formed is composed of anodic oxide combined with polyacid, which forms a protective layer on the metal of improved corrosion resistance. The metal oxide-organic complex is well-suited to bond light sensitive coatings thereto. The metal may be steel or aluminum. The process is economical and the product novel.

    摘要: Light sensitive coating compositions containing a dyestuff, which compositions exhibit improved adhesion to transparent film substrates, are disclosed. For example, the adhesion between a polyester base film and a light sensitive coating composition containing a light sensitive diazo material, a resinous binder and a dyestuff is improved by additionally incorporating into the composition an effective amount of an adhesion promoter based on a copolyester obtained by the esterification and subsequent polymerization of a lower alkylene glycol with a mixture of terephthalic acid, isophthalic acid, and at least one acyclic dicarboxylic acid. These coating compositions may be readily removed from the base film by appropriate lithographic developer solutions without substantial residual staining of the film by the dyestuff present in the coating composition.

    摘要: This invention relates to water developable, negative working photosensitized sheet constructions which, upon exposure to an actinic radiation source through a screened image, can accurately reproduce said image. The construction is useful as a color proofing film which can be employed to predict the image quality from a lithographic printing process. The invention provides both overlay and transfer type proofing sheets which have good fingerprint resistance.
