    摘要： This invention relates to a latex composition comprising water as a continuous phase and, as the dispersed phase, hydrophobic polymer particles having associated therewith an infrared polymethine dye having covalently bonded thereto a phenylenediamine moiety. It further relates to a process for associating dye with polymer particles in a latex composition comprising the steps of: (1) forming a dye solution by dissolving a polymethine dye having covalently bonded thereto a phenylenediamine moiety in a water miscible or immiscible organic solvent; (2) forming a latex by dispersing hydrophobic polymer particles in an aqueous continuous phase; (3) blending the latex with the dye solution; and (4) loading of the polymer particles by removing the organic solvent, thereby forming a latex having the polymethine dye associated therewith.

    摘要： A negative-working lithographic printing plate precursor is designed for improved printout or contrast between exposed and non-exposed regions in its imageable layer. The imaged precursor can be developed on-press. The improvement in printout is achieved by using a combination of at least two infrared radiation absorbing cyanine dyes. At least one of these cyanine dyes comprises a methine chain substituent that comprises a group represented by Structure (I): wherein Q1 and Q2 are hydrogen atoms or the same or different monovalent substituents, or Q1 and Q2 together provide carbon or heteroatoms to form a substituted or unsubstituted unsaturated ring. At least one other infrared radiation absorbing cyanine dyes does not comprise a group represented by Structure (I).

    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.
