摘要： A lithographic printing plate that works according to the silver salt diffusion transfer reversal process is disclosed. The lithographic properties of said plate can be improved by incorporating a hydrophilic amphoteric block copolymer, comprising a non-ionic block of acrylic units with pendant nitrile groups and an acrylamid(in)e block which comprises units with pendant basic and acidic groups. The hydrophilic amphoteric block copolymer is preferentially present in the image receiving layer of the lithographic printing plate. In an alternative embodiment, said block copolymer may be present in a treating solution used for processing said plate or applied onto said plate while printing. The hydrophilicity of the printing plate's surface is improved without deteriorating the ink-acceptance in the printing areas.

摘要： A process for producing polymers of .alpha., .omega.-unsaturated conjugated compounds, which includes reacting a compound of the formula (I),B--A--C (I)whereinB denotes a sp.sup.3 -hybridized carbon atom carrying at least one hydrogen atom,A denotes a conjugated-.pi.-system or a --CH.dbd.CH--group, andC denotes a carbon atom carrying at least one leaving group,with a base in a solvent. On reaction of the base with the compound of the formula (I) a polymer is formed as a by-product essentially soluble in the solvent and a solid is formed as a by-product which is essentially insoluble in the solvent. According to the process, chemically and thermally stable, high molecular weight polymers of high purity and high regularity are obtained in good yield. If the products of the process carry groups that undergo elimination, forming double bonds, high quality electroluminescent materials can be prepared.
