Abstract: The invention relates to colloidal films of metal oxide particles and organic acids, wherein the organic acid contains at least two carboxylic acid groups. These films can be used in many applications, including light-emitting devices and photovoltaic cells. When added to the metal oxide particles, the organic acids provide good mechanical strength and prevent the colloidal films from delaminating and flaking, while simultaneously avoiding the need for high temperature sintering.

Abstract: A process for producing and fixing an image uses an imaging medium comprising an acid-generating layer or phase comprising a mixture of a superacid precursor, a sensitizer and a secondary acid generator, and a color-change layer comprising an image dye. The sensitizer can absorb radiation of a sensitizer wavelength which does not, in the absence of the sensitizer, cause decomposition of the superacid precursor to form the corresponding superacid. The secondary acid generator is capable of acid-catalyzed thermal decomposition by the first acid to form a second acid, and the image dye undergoes a color change upon contact with the second acid. The medium is imagewise exposed to radiation of the sensitizer wavelength, thereby causing the sensitizer, in exposed areas, to decompose superacid precursor with formation of the fist acid. The medium is then heated to cause, in the exposed areas, acid-catalyzed thermal decomposition of the secondary acid generator and formation of the second acid.

Abstract: Multi-functional vinylbenzyl and vinylphenyl pendant thymine (and uracil) groups are disclosed. The monomers can be used for the production of polymers useful in photoresist and other compositions as a function of the crosslinking reactivity of the pendant groups. Images in polymer are provided by exposure to actinic radiation (e.g., UV), containing such polymer and by solvent removal of non-exposed regions.

Abstract: An imaging process uses an imaging medium comprising a polymer having a plurality of first groups. This polymer is imagewise contacted with an imaging reagent comprising a plurality of second groups, thus causing, in the areas of the medium exposed to the imaging reagent, the second groups to react with the first groups and form a colored material, and thereby forming an image on the imaging medium. One of the first and second groups comprises a benzotriazinone or benzothiatriazine-4,4-dioxide benzotriazinone moiety and the other comprises a naphthol or a pyrazalone moiety.

The pendent "b" group contain hydrogen-bonding sites for promotion of self-associated aggregation and ring unsaturation for photocyclization and control of physical properties (e.g., water insensitivity) of the image-receiving layer. The copolymeric mordant materials can be utilized as image-receiving layers in photographic products and processes of the diffusion transfer type.

Abstract: Hydroquinones form stable hydrogen-bonded complexes with N,N,N',N'-tetrasubstituted diamides of aromatic dicarboxylic acids in which two carboxyl groups are arranged para to one another on the same phenyl ring. These complexes are useful in rendering the hydroquinones more water-dispersible to assist their incorporation into photographic products. Also, the diamides may be incorporated into photographic products to reduce or eliminate various problems associated with hydroquinones, including migration of hydroquinones within the product during storage and the discoloration of images on storage due to oxidation of hydroquinone present in an image-receiving element of the photographic product.
