摘要： Radiation-sensitive compositions which are especially useful in the production of negative-working lithographic printing plates comprise a photocrosslinkable polymer containing the photosensitive group ##STR1## as an integral part of the polymer backbone and, in an amount sufficient to improve the properties of the composition, both a poly(N-acyl-alkyleneimine) and an unsaturated polyester such as a polyester derived from fumaric acid and a 4,4'-isopropylidenediphenol. The combination of a poly(N-acylalkyleneimine) and an unsaturated polyester improves the properties of the radiation-sensitive composition in regard to such factors as shelf life, image contrast, developability, ink receptivity and reduction in mottle and thereby provides a superior lithographic printing plate.

摘要： An anodized aluminum support for use in a lithographic printing plate comprises a bilayered anodic surface having a total average thickness of at least 0.10 micrometers consisting essentially of oxides and phosphates of aluminum present in a coverage of greater than 100 milligrams per square meter of support. The anodic surface comprises an upper stratum comprising pores having an average diameter of 1.0.times.10.sup.-8 -7.5.times.10.sup.-8 m and a lower stratum comprising pores having an average diameter substantially greater than the pores in the upper stratum. The support is prepared by a two-stage process of anodically oxidizing at least one surface of an aluminium plate in an aqueous electrolyte comprising phosphoric acid under conditions wherein the upper stratum is formed in the first stage and the lower stratum is formed in the second stage. A lithographic printing plate comprising a radiation-sensitive layer and the above-described support exhibits improved resistance to staining.
