    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 present invention relates to supports for lithographic printing plates and to a process for producing the same. In particular, the invention relates to aluminum plates having an electrochemically grained and anodized surface which is has a smooth, shiny surface and hence greater image contrast when a lithographic image is formed thereon. The surface has a substantially uniform surface topography comprising peaks and valleys and surface roughness parameters wherein Ra ranges from about 0.10 to about 0.50 microns, Rz ranges from about 0.00 to about 5.00 microns, Rt ranges from about 0.00 to about 6.00 microns and Rp ranges from about 0.00 to about 4.00 microns. The surface preferably has tristimulus color coordinate values wherein L ranges from about 35.00 to about 75.00, a ranges from about -4.00 to about +4.00 and b ranges from about -4.00 to about +4.00.
