    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： On press developable negative-working, on-press developable imageable elements have improved printout qualities with an incorporated infrared radiation absorbing compound that has a cyanine dye chromophore that is represented by the following Structure (CHROMOPHORE): wherein one or both of Q1 and Q2 are independently substituted or unsubstituted acyl groups —(C═O)—R3′ and —(C═O)—R4′ respectively, wherein R3′ and R4′ are independently substituted or unsubstituted alkyl or aryl groups, or they are joined together to form a ring structure, or one of Q1 and Q2 is hydrogen and the other is a substituted or unsubstituted acyl group, A and A′ are independently —S—, —O—, —NH—, —CH2—, or —CR′R″— groups wherein R′ and R″ are independently substituted or unsubstituted alkyl groups, or R′ and R″ together can form a substituted or unsubstituted cyclic group, Z represents the carbon atoms needed to form a 5- to 7-membered carbocyclic ring, Z1 and Z2 are independently substituted or unsubstituted benzo or naphtho condensed rings, and R1′ and R2′ are independently substituted or unsubstituted alkyl, cycloalkyl, or aryl groups.

    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).
