    摘要： A presensitized plate comprises a substrate having a hydrophilic surface provided thereon with a light-sensitive layer containing an alkaline water-soluble or swellable photocrosslinkable polymer carrying photodimerizable unsaturated double bonds and an optional intermediate layer between the substrate and the light-sensitive layer wherein the light-sensitive layer and/or the intermediate layer contain a co-polycondensed diazo resin having, as the structural units, those derived from an aromatic compound having at least one carboxyl group and an aromatic diazonium compound, for instance 4-diazodiphenylamine salt. The light-sensitive layer and/or the intermediate layer of the plate exhibit high adhesion to the substrate or the like while maintaining high sensitivity and excellent quality thereof and the plate can be developed with an alkaline water to provide lithographic printing plates having excellent quality such as printing durability.

    摘要： A process for producing a polyimide/metallic foil composite film having a curvature radius of at least 25 cm and which is substantially free from curling is described, comprising coating a solution of a polyimide precursor in an organic polar solvent on a 1 to 500 .mu.m thick metallic foil, the polyimide precursor being prepared by reacting a diamine component comprising p-phenylenediamine and an aromatic tetracarboxylic acid component comprising 3,3',4,4'-biphenyltetracarboxylic dianhydride or its derivative; heat-drying the above-prepared coating in the state that the metallic foil is fixed; and then heating it at a high temperature to form a 5 to 200 .mu.m thick polyimide film. This composite film does not substantially curl in either the lengthwise and widthwise directions and is very suitable for use in the production of an electric circuit board.

    摘要： A light-sensitive composition which comprises at least one polymeric compound having both photocross-linkable groups and functional groups carrying P--OH bonds. The light-sensitive composition can effectively be employed for making lithographic printing plates, IC circuits and photomasks. The light-sensitive composition shows excellent practically acceptable developability with either of an aqueous alkali developer and an aqueous alkaline solution containing or free of organic substances such as organic solvents and/or surfacants. Moreover, when it is used to form PS plates, the resulting lithographic printing plates never cause background contamination and can provide a large number of good printed matters. The composition makes it possible to develop negative working PS plates with developers for positive working PS plates. Therefore, when both positive and negative working PS plates are processed, the use of the composition can save various troubles.
