    摘要： Negative-working imageable elements such as lithographic printing plate precursors, include a free-radically polymerizable component, an initiator composition that is capable of generating free radicals sufficient to initiate polymerization of the free-radically polymerizable component upon exposure to imaging radiation in the presence of a radiation absorbing compound, a radiation absorbing compound, an aerobic free radical inhibitor, optionally a polymeric binder that is not a free radically polymerizable component, and an anaerobic free radical inhibitor. The molar ratio of the anaerobic free radical inhibitor to the aerobic free radical inhibitor is at least 1:1. This combination of inhibitors provides increased shelf life and good latent image stability particularly when the element includes a polymeric topcoat layer that functions as an oxygen barrier.

    摘要： Process for the production of lithographic printing plates comprising (a) providing a lithographic substrate with a hydrophilic surface; (b) applying a negative working radiation-sensitive composition onto the hydrophilic surface, wherein the composition comprises: (i) one or more types of monomers and/or oligomers and/or polymers, each comprising at least one ethylenically unsaturated group accessible to a free-radical polymerization, (ii) at least one sensitizer which in the presence of at least one coinitiator and upon exposure to radiation of a wavelength of 300 to 750 to 1,100 nm initiates the free-radical polymerization of component (i); and (iii) at least one binder with acidic functional groups and is substantially not sensitive to the wavelength range of 480 to 750 nm; (c) image-wise exposure of the resulting negative working lithographic printing plate precursor to radiation selected from the wavelength range of 300 to 750 to 1,100 nm depending on the sensitizer or initiator system used; and (d) removing the non-irradiated areas by means of a treatment with an alkaline developer with a pH value in the range of 9 to 14 comprising (i) water, (ii) one or more alkali hydroxides in an amount sufficient for adjusting a pH value in the range of 9 to 14; and (iii) 1 to 30 wt.-% of at least one compound of formula (I) wherein R1, R2, R3 and R4 are each independently selected from C1-C12 alkyl groups and aryl groups, X is selected from —CH═CH—, —C≡C—, formula (II), formula (III), and formula (IV), n+m results in a value of 2 to 30 and p+q results in a value of 0 to 30, wherein in the case of p+q≠0 the ethylene oxide and propylene oxide units are present as blocks or randomly distributed.

    摘要： Lithographic printing plates are provided by imagewise exposing negative-working lithographic printing plate precursors having a negative-working radiation-sensitive imageable layer, followed by contacting with a processing solution that has a pH of at least 7 and up to and including 11. This processing solution also includes component (1) that is a nitrogen-containing base having an atmospheric pressure melting point of at least 40° C.; component (2) that is a non-ionic surfactant that independently has an atmospheric pressure melting point, glass transition temperature, or pour point of at least 40° C.; component (3) that is a hydroxy-containing solution promoter; and component (4) that is a hydrophilic surface protective compound. The method is carried out in a manner such that the exposed and processed precursor is not further treated with any liquid (such as gumming or rinsing solution) between processing and mounting onto a printing press.
