A metal oxide coating and a method of forming the metal oxide coating are disclosed, wherein the metal oxide coating composition includes a metal oxide precursor of the metal oxide, the metal oxide, or a combination thereof, and a solvent of secondary or tertiary C&#x2013;Calcohol.

Metal oxide coating

An ink jet ink composition comprising water, a humectant, a polyvalent transition metal complex of an 8-heterocyclylazo-5-hydroxy-quinoline and an anti-kogation material comprising an alkali metal salt of a monobasic organic or inorganic acid. Examples of anti-kogation materials useful in the invention include sodium hexanoate, sodium sulfate, sodium propionate, sodium benzoate, sodium p-toluenesulfonate, sodium acetate, sodium bromide, sodium nitrate, potassium nitrate, lithium nitrate, lithium acetate, tetramethylammonium acetate and tetrabutylammonium bromide.

Ink jet printing method

A colorant-donor element for laser thermal transfer comprising a support having thereon a colorant layer comprising a colorant dispersed in a binder the colorant layer having associated therewith an infrared-absorbing cyanine colorant having a sulfonic acid group, the cyanine colorant having the following formula:

Stabilizer for infrared-absorbing cyanine colorant for laser-colorant transfer

A stable coating composition comprising an image dye, an infrared-absorbing dye, a polymeric binder, an organic solvent and a complexing agent having the following formula:

Stable coating composition

This invention relates to a dye-donor element for thermal dye transfer comprising a support having thereon a dye layer comprising a naphthol-p-phenylenediamine cyan dye in a polymeric binder, the dye layer also containing a stabilizer, the stabilizer comprising a compound containing a nitroxyl free radical and having a molecular weight of at least about 400 or a hydroxylamine moiety and having a molecular weight of at least about 330, the stabilizer being present in the amount of 5-10 mole % based on the weight of the dye.

Stabilizers for dye-donor element used in thermal dye transfer

An imaging composition and element are disclosed wherein an aromatic dialdehyde reacts with amines generated in response to activating radiation. Improved binders are used to insure sufficient retention of the volatile dialdehyde prior to imaging.

Imaging processes, elements and compositions featuring dye-retaining

A presensitized printing plate contains a leuco dye and an organic azide to provide a print-out image when the presensitized plate is exposed to light. Development of the plate may remove the print-out image but provides a relief image which may be dyed or pigmented. The light sensitive unsaturated materials used to provide the relief image include photocrosslinkable unsaturated polymers containing the moiety ##STR1## as part of the polymer backbone.
