    摘要： A negative-working radiation-sensitive composition includes a polymeric binder comprising a polymer backbone and having attached thereto a carbazole derivative represented by the following Structure (I): wherein Y is a direct bond or a linking group, and R1 to R8 are independently hydrogen, or an alkyl, alkenyl, aryl, halo, cyano, alkoxy, acyl, acyloxy, or carboxylate groups, or any adjacent R1 through R8 groups can together form a carbocyclic or heterocyclic group or a fused aromatic ring. The composition can be sensitive to radiation having a maximum wavelength of from about 150 to about 1500 nm, and can be used to prepare negative-working imageable elements that be imaged and developed as lithographic printing plates.

    摘要： The present invention provides an imageable member having an imageable layer including a heat-sensitive ionomer characterized by a net positive or negative charge, and a photothermal conversion material. The photothermal conversion material includes carbonaceous particles having thereon both an organic moiety including an ionic substituent having like charge as the ionomer, and a group represented by the formula —X-[NIon]p-Rterminal; wherein X represents an aromatic group or an alkyl group, NIon represents a non-ionic, non-ionizable group, Rterminal represents hydrogen, an aromatic group, an alkoxy group, or an alkyl group, and p is an integer from 1 to about 500. The heat-sensitive ionomer and modified carbonaceous particles can be formulated in water or water-miscible solvents without agglomeration. Imageable members utilizing the modified carbonaceous particles as a photothermal conversion material exhibit acceptable optical density and exposure speed, and imaged members made therefrom exhibit excellent background performance.

    摘要： An imaging member, such as a negative-working printing plate or on-press cylinder, can be prepared using a hydrophilic imaging layer comprising a hydrophilic heat-sensitive polymer containing a crosslinking agent comprising ionic groups and epoxy groups. This polymer may comprise quaternary ammonium carboxylate groups which may include at least one substituted-alkylene(C1-C3)-phenyl group. The imaging member also includes an infrared radiation sensitive material to provide added sensitivity to heat that can be supplied by laser irradiation in the IR region. The heat-sensitive polymer may be “switchable” in response to heat, and provides a lithographic image without wet processing.

    摘要： A method for reducing start up blinding in no-process lithographic printing plates is disclosed. An imageable element, comprising an imageable layer over a substrate, is thermally imaged. The imageable layer comprises a thermally sensitive polymer that comprises quaternary ammonium salts of carboxylic acids. Following imaging, the surface of the imaged imageable is contacted with an aqueous solution comprising 0.05 wt % to about 5 wt % of an added organic acid having a pKa of about 1 to about 6. This reduces the amount of waste produced by the printing process by reducing the number of unusable sheets produced during the “make ready” process.
