    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: Disclosed is a dye combination and a thermal dye transfer yellow donor element containing the combination of dyes useful for forming a light stable yellow image comprising a yellow dye having the formula: wherein: R1 and R2 each independently represents an alkyl group of from 1 to 10 carbons atoms or a cycloalkyl group of from 5 to 7 carbon atoms; R3 and R4 each independently represents hydrogen, or an unsubstituted lower alkyl group of 1 to 4 carbon atoms; each Y independently represents halogen, or a lower alkyl or alkoxy group of 1 to 4 carbon atoms; and m is 0 to 4. Such a dye combination and element provide improved color and stability, especially for proofing.

    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.
