    摘要： The present invention provides a thermally sensitive composition that may be coated as a water-borne material onto a substrate to yield a printing plate precursor having an imageable coating. The thermally sensitive composition comprises a sulfated phenolic resin. The sulfated phenolic resin may be a sulfated novolak resin or a sulfated resole resin, for example. The thermally sensitive composition may include a water-soluble binder, such as polyvinyl pyrrolidone, and a radiation-absorbing component. The invention also provides a printing plate precursor that is developed in water after imaging. The precursor does not require chemical development with a developing solution containing organic solvents or inorganic additives. The imaged precursor is on-press-developable when used with a fountain solution. Methods for making and using the precursor are also provided.

    摘要： A method for forming an image useful as a lithographic printing plate using an ink jet technique is disclosed. An imageable precursor that comprises an overlayer over a substrate is imaged with an imaging agent and developed with water or fountain solution. The overlayer comprises a thiosulfate-containing polymer. The imaging agent is a polar organic liquid comprising at least one functional group selected from hydroxyl, cyano, and lactone. The method retains the advantages of using data in digital form, yet does not require expensive and complex equipment for imaging. The imaged precursor can be developed with water or on press using fountain solution.

    摘要： The present invention provides a method of imaging a printing plate precursor in which a printing plate precursor including a substrate and an image forming layer is imagewise contacted with a catalyst, for example, by imagewise ink-jet application. The image forming layer is then heated and developed in a suitable developer liquid such that portions of the image forming layer that are contacted with the catalyst resist development while portions of the image forming layer that are not contacted with the catalyst are removed during development.

    摘要： A concentrated developer can be prepared with less than 60 weight % water and still remain in a single phase with little or no haze or precipitation. This developer concentrate also includes a water-soluble or water-miscible organic solvent, one or more alkyl ether carboxylic acid, coconut oil alkanolamine, coconut fatty alcohol polyglycol ether, β-naphtholethoxylate, and block propylene oxide-ethylene oxide in an amount of at least 0.1 and up to 50 weight % solids, and optionally an alkyl naphthalene sulfonate in an amount of up to 40 weight % solids. The developer concentrate can be diluted up to 80:1 or greater with water and used to process imaged lithographic printing plate precursors.

    摘要： A negative-working imageable element has an imageable layer that includes an infrared radiation absorbing dye that upon exposure to thermal irradiation, changes from colorless to a visible color or from one visible color to another visible color, providing a ΔE of at least 5 between the exposed and non-exposed regions of the imageable layer within 3 hours of its exposure to 300 mJ/cm2 at a laser power of 15 Watts. The imageable element can be imaged to provide images with improved contrast for print-out. The imageable layer includes a primary polymeric binder that has a backbone to which are attached pendant poly(alkylene oxide) side chains, cyano groups, or both, and is optionally present in the form of discrete particles.

    摘要： Negative-working imageable elements have an imageable layer comprising a free radically polymerizable component, an initiator composition capable of generating radicals sufficient to initiate polymerization of the free radically polymerizable component upon exposure to imaging radiation, a radiation absorbing compound, one or more polymeric binders, and at least 5 weight % of core-shell particles comprising a hydrophobic polymeric core and a hydrophilic polymeric shell that is covalently bound to the polymeric core. The hydrophilic polymeric shell has one or more zwitterionic functional groups. These elements can be imaged such as by IR lasers to provide lithographic printing plates.
