    摘要： Positive-working lithographic printing plate precursors have an inner layer that includes a polymeric binder having an acid number of at least 30 mg KOH/g of polymer to and including 150 mg KOH/g of polymer, at least 3 weight % of recurring units derived from one or more N-alkoxymethyl(alkyl)acrylamides or alkoxymethyl(alkyl)acrylates, at least 2 weight % of recurring units having pendant 1H-tetrazole groups, and at least 10 weight % of recurring units having pendant cyano groups. The use of such polymeric binders in the inner layer provides good bakeability and chemical solvent resistance. Such positive-working lithographic printing plate precursors also include an outer layer disposed over the inner layer, which outer layer comprises an infrared radiation absorbing compound.

    摘要： A method for applying a matting layer to a radiation-sensitive layer of a printing plate precursor is disclosed. The method comprises: (a) providing a matting composition comprising a polymer and a solvent, wherein the matting composition has a solid content of more than 10% and no more than 50% by weight based on the total composition; and (b) spraying the matting composition on the radiation-sensitive layer using an electrostatically aided rotary atomizer having a bell speed of more than 10,000 rpm, wherein the distance between the bell and the radiation-sensitive layer to be coated is less than 30 cm. The printing plate precursor may be in the form of a moving web. The method of the present invention can be used for matting any kind of radiation-sensitive layer of conventional positive and negative working lithographic printing plate precursors.
