    摘要: Polymeric mordants which are capable of converting to non-mordanting species in an alkaline environment are described. The mordants can be used in photographic elements to temporarily mordant a photographically useful dye material, such as a light-filter or anti-halation dye or a diffusion transfer image dye-providing material, and then release the dye material during processing of the element with an alkaline processing composition.

    摘要: There is disclosed a diffusion transfer photographic system wherein development of an exposed photosensitive element with an aqueous alkaline processing composition is effected in the presence of a compound represented by the formula ##STR1## wherein X represents the nonmetallic atoms necessary to form a nucleus which completes a 5- or 6-membered heterocyclic moiety on said structure including substituted rings and fused rings; R is H, an alkali metal or a group which is cleavable in a photographic aqueous alkaline processing composition; and R.sub.1 is either a group which has a pKa of from about 7 to about 14 which is ionizable to an anion whereby the silver salt of the mercaptan (resulting from cleavage or ionization of --SR) is rendered more soluble in the pH range within which R.sub.1 is ionized to an anion than it is below that pH range, or a precursor of such a group.

    摘要: Copolymeric mordant materials containing recurring units according to the following formula are disclosed: ##STR1## In such copolymers, each of R.sup.1, R.sup.2 and R.sup.3 can independently be alkyl; substituted alkyl; cycloalkyl; aryl; aralkyl; alkaryl; or at least two of R.sup.1, R.sup.2 and R.sup.3, together with the quaternary nitrogen atom to which they are bonded, can complete a saturated or unsaturated, substituted or unsubstituted nitrogen-containing heterocyclic ring; and X is an anion. The molar ratio of a:b can range from about 0.1:1 to about 10:1, e.g., about 0.3:1 to about 3:1.The copolymeric mordant materials can be utilized as image-receiving layers and in photographic products and processes of the diffusion transfer type. The mordants are especially adapted to the production of dye images free of objectionable haze, yellowing or related image defects.

    摘要: An image-receiving element for use in photographic and photothermographic diffusion transfer film units of the type wherein the image-receiving element is designed to be removed or "peeled-apart" from a photosensitive element following exposure and processing. The present image-receiving element comprises in sequence, a support, an image-receiving layer, and a strip-coat layer. The strip-coat layer serves to facilitate separation of the image-receiving layer from a photosensitive element after processing. The strip-coat layer comprises a copolymer including: 1) at least about 50% by weight of monomer units, the same or different, derived from an ethylenically unsaturated carboxylic acid or salt thereof, 2) at least about 15% by weight of monomer units of vinyl pyrrolidone, and 3) at least about 5% by weight of monomer units, the same or different, represented by the formula: ##STR1## wherein R.sub.1 of each monomer unit is independently selected from: hydrogen, a substituted or unsubstituted alkyl having 1 to 4 carbon atoms, cyano, and halogen; X of each monomer unit is independently selected from --NH-- or --O--; and R.sub.2 of each monomer unit is independently selected from a hydroxy substituted alkyl group.

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.

    摘要: 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.
