摘要： Provided herein is a brushgraining process to improve the quality of lithographic printing plate substrate surfaces. In the process, the surface is brushed in an aqueous slurry comprising a mixture of particulates of alumina and quartz in a weight ratio range 95:5 to 5:95, with the particulates being in the size range of 1-20 microns. Such a process surprisingly lessens the number of scratches produced on the substrate surface than when compared to using alumina alone or quartz alone or a mixture of alumina and quartz with particle sizes higher than the range disclosed.

摘要： A color ant dispersion having a pigment, a solvent composition of a C1-C8 aliphatic alcohol, a mono- or di-C1-C8 alkylene glycol C1-C8 alkyl ether, or a cyclic ketone; and an aqueous alkaline soluble or swellable polymeric compound which is the reaction product of a hydroxy containing polymer and an anhydride in the presence of a catalytic amount of a tertiary amine catalyst. The pigment and the polymeric compound are present in a high relative weight ratio of from about 0.75:1.25 to about 1.25:0.75. An admixture of the dispersion, a light sensitive component diazonium compound or photopolymerizable composition and an aqueous alkaline soluble or swellable polymeric binder, when coated and dried onto a substrate, forms a photographic element, which when imagewise exposed and developed has an exceptionally high contrast between image and removed non-image areas.

摘要： The process for manufacturing materials, in the form of sheets, foils or webs, comprised of chemically, mechanically and/or electrochemically roughened and anodically oxidized aluminum or an aluminum alloy, which process is performed with two hydrophilizing post-treatment steps. In post-treatment step (a) a supported aluminum oxide layer is treated with an aqueous alkali metal silicate solution which optionally contains alkaline earth metal ions, and in step (b) the aluminum oxide layer is separately treated with an aqueous solution containing at least one organic polymer comprised of vinylphosphonic acid and/or vinylmethylphosphinic acid monomers, such as polyvinylphosphonic acid. Treatment of the aluminum oxide layer is accomplished by means of immersion and/or electrochemically. Materials prepared by this process are particularly useful as supports for offset printing plates, showing an improved resistance to alkali and a reduced tendency to adsorb dyestuff.
