The present invention relates to a cyan dye donor element for thermal transfer imaging comprising a support having thereon a dye layer comprising a mixture of at least two cyan dyes dispersed in a polymeric binder, wherein at least one of the at least two cyan dyes is a light stabilizing dye represented by Formula I and a thermal image recording method utilizing the same cyan dye donor element. The present invention also relates to a cyan inkjet dye comprising a light stabilizing cyan dye represented by Formula I.

Stabilized dyes for thermal dye transfer materials

The present invention relates to a thermal donor comprising a dye mixture and a urea light-stabilizing compound, wherein the light-stabilizing compound is represented by structure I: wherein:

Urea stabilizers for thermal dye transfer materials

A magenta dye combination having improved lightfastness and keeping properties is described, wherein the magenta dye combination can be used in thermal printing.

Magenta dye mixture

A photographic element comprises a silver halide emulsion layer having associated therewith a dye forming coupler and a combination of a carbonamide compound, a phenolic compound, and an electron-rich compound. Such a combination provides improved dye stability.

Stabilized silver halide photographic element

A photographic element comprises a silver halide emulsion layer having associated therewith a dye forming coupler and a compound of the following Formula I1: wherein

Coupler and image dye light-stabilizing systems

A photographic element comprises a light-sensitive silver halide emulsion layer having associated therewith (a) a 1H-pyrazolo[1,5-b][1,2,4]triazole dye-forming coupler; (b) a sulfonamide compound free of aromatic substituents directly linked to the sulfonamide nitrogen or sulfur atoms and (c) a dialkoxy substituted aromatic compound.

Silver halide photographic element and process

Photographic elements are disclosed comprising a silver halide emulsion layer having associated therewith a dye forming coupler and a compound of the following Formula I:RRN&#x2014;C(O)&#x2014;(R)&#x2014;C(O)&#x2014;NRRwherein R represents a hydrocarbon linking group; p=0 or 1; and each of R, R, Rand Rindependently represents an aromatic, cyclic, linear or branched chain hydrocarbon group, or Rand Ror Rand Rcombine together to form a ring with the associated nitrogen atom to which they are attached; with the proviso (i) at least one of R, R, Rand Rcomprises an aromatic, cyclic, secondary alkyl, or otherwise or branched hydrocarbon group, or (ii) at least Rand Ror Rand Rcombine together to form a ring with the associated nitrogen atom. Photographic elements of the present invention upon exposure and photographic processing exhibit good activity and yield dye images that have unexpected and substantial improvements in the stability of the formed image dyes.

Photographic element with dye-forming coupler and image dye stabilizing coupler solvent

Disclosed is a photographic element comprising a light sensitive silver halide emulsion layer and, having associated with that layer, a 1H-pyrazo&lsqb;1,5-b&rsqb;-1,2,4-triazole dye forming coupler having a fully substituted carbon atom at the 6-position, a chloro group at the 7-position, and, at the 2-position, a propionic ester moiety.

Photographic material comprising a bicyclic pyrazolotriazole coupler with improved hue

Photographic element, compound, and process

Photographic element containing a red dye-forming pyrazolotriazole coupler

Photographic element with dye-forming coupler and image dye stabilizing compound

This invention relates to a silver halide photographic element containing a phenolic infrared dye-forming coupler bearing in the 2-position either a benzamido group substituted with a sulfonyl group or a heterocyclic carbonamido group, and bearing in the 5-position a non-carbonamido group, which element is useful for incorporating and recovering metadata, such as sound data, into a photographic image and is specifically concerned with the incorporation of non-visually perceptible sound information into a photograph.

Infrared couplers for incorporating and recovering metadata

Photographic element containing azole couplers

Disclosed is a photographic element comprising a light-sensitive silver halide emulsion layer having associated therewith a coupler that forms a dye for which the &lgr; using spin-coating is shifted towards the infrared region of the spectrum by at least 30 nm, when compared to the &lgr; of the same dye in solution form, to a value of at least 700 nm. Such an element is useful for recording metadata with an image.
