    摘要: A positive image can be obtained from a positive-working element that is sensitive to infrared radiation. The element comprises an imaging layer containing an alkali-soluble reactive resin (such as a phenolic resin), an infrared radiation absorbing compound, a thermochemical acid generating compound, and a dissolution inhibitor that has acid-cleavable C—O—C groups. Upon laser exposure, a Bronsted acid is generated which then breaks the bonds of the C—O—C groups, allowing the exposed regions of the reactive resin to be solubilized in an alkaline developer solution.

    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 polybasic organic acid as electrolyte. 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. Repetitive cycle pulsed direct current is used. 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, aluminum or magnesium.
