    摘要: There is described a water-less lithographic plate precursor which comprises on an aluminium plate a light-sensitive composition which comprises a polymer with hydroxy functional groups, an acid generator which when light exposed yields an acid together with a silyl ether of general formula (I), where Rf is a fluoroaliphatic group having 3 to 10 carbon atoms, Y is oxygen, SO.sub.2, carbonyl or a direct link, X is N R.sub.4 where R.sub.4 is hydrogen or lower alkyl having up to six carbon atoms or is a direct link, each of R.sub.1, R.sub.2 and R.sub.3 are lower alkyl groups having up to six carbon atoms and R.sub.5 is a lower alkyl group having up to six carbon atoms. ##STR1##

    摘要: A method for preparing a printing form and a method of printing are disclosed. A coating of a radiation sensitive ink on a lithographic support having a hydrophilic surface is imaged. The unexposed areas of the coating are removed to produce a printing form, which is used for printing. Preferably, the same radiation sensitive ink is used for printing as is used in the coating, and, preferably, the desired printing run length is predetermined and the thickness of the coating determined according to the desired run length.

    摘要: Described is a method of treating an article having at its surface oxide or hydroxide moieties, as well as the resulting treated article. The method includes priming the surface of the article by contact with an alkoxysilane in an aprotic organic solvent in the presence of an acid catalyst so that the alkoxysilane reacts with the oxide or hydroxide moieties of the surface. This yields a primed surface. A polymer is then reacted with one or more amino, hydroxyl, carboxylic acid and/or acid anhydride groups on the surface to covalently couple the polymer to the primed surface via the alkoxysilane. The reaction with the polymer is not a free-radical reaction.
