  • Patent number: 4268605
    Abstract: Organic substrate materials having absorption maxima between 300 and 800 nm can be stabilized against the action of light by the presence of at least one compound represented by either of the following general formula (I) or (II): ##STR1## where M represents a metal atom selected from the group comprising Cu, Co, Ni, Pd and Pt; R.sup.1, R.sup.2, R.sup.3 and R.sup.4, may be the same or different and each represents a hydrogen atom, a halogen atom, cyano group, an alkyl group, an aryl group, a cycloalkyl group, or a heterocyclic ring, each of the latter four groups being bonded directly or via a divalent connecting group to the corresponding carbon atom of the benzene ring. Alternatively, R.sup.1 and R.sup.2, R.sup.2 and R.sup.3, or R.sup.3 and R.sup.4, may combine to represent the non-metallic atoms necessary to complete a 6-membered ring.R.sup.5 and R.sup.

  • Patent number: 4243737
    Abstract: An image-forming element is disclosed comprised of a support and a coating thereon containing a cobalt(III)complex and a compound containing a conjugated .pi. bonding system capable of forming at least a bidentate chelate with cobalt(III). The coating is predominantly free of anions which will form conjugate acids by deprotonation of a cobalt(II)complex containing the chelating compound. In one preferred form the image-forming element is radiation-sensitive. In this form the image-forming element can contain a photoactivator capable of initiating reduction of the cobalt(III)complex. An imaging process is disclosed in which the coating is exposed to actinic radiation to produce an image. Images can be recorded directly within the image-forming coating or in a separate image-recording element or layer by use of the residual cobalt(III)complex or by use of one or more of the reaction products produced by exposure.

  • Patent number: 4228257
    Abstract: A polymer comprising acrylamide units or anionic sulfonate units and a unit having the formula: ##STR1## wherein: R is H, halogen or alkyl;L is a linking group; andM is H, an ammonium cation or an alkali metal, can be metallized to form a metallized polymer. The metallized polymer is useful either as or with a mordant for dyes or dye formers that chelate metals.

  • Patent number: 4211559
    Abstract: Difunctional compounds wherein one of said functions is a hard or soft atom that ionizes to the corresponding anion in alkaline solution to combine with silver cation and the other of said functions is a non-ionizable soft base that additionally combines with said silver cation are employed as silver halide complexing agents in photography. In a preferred embodiment, the difunctional compounds possess (a) an O, N or C atom that ionizes to the corresponding O.crclbar., N.crclbar. or C.crclbar. anion in basic solution and (b) an --S-- containing moiety excluding --SH and moieties that form --S.crclbar. in basic solution wherein the --S-- of said moiety is positioned alpha, beta, gamma, delta, epsilon or zeta to said anion.

  • Patent number: 4204993
    Abstract: Photographic elements, diffusion transfer assemblages and processes are described which employ a novel nondiffusible compound having a releasable 6-arylazo-2-amino-3-pyridinol dye moiety or precursor thereof. The compound contains in the ortho position of the arylazo moiety a ballasted carrier moiety attached thereto either through a sulfonamido linking group or through the oxygen of a ##STR1## which said ballasted carrier moiety contains, the ballasted carrier moiety being capable of releasing the diffusible 6-arylazo-2-amino-3-pyridinol dye or precursor thereof under alkaline conditions. The dye is transferred imagewise to an image-receiving layer, where it is contacted with metal ions to form a metal-complexed 6-arylazo-2-amino-3-pyridinol dye transfer image of excellent stability.

  • Patent number: 4197080
    Abstract: Radiation-cleavable nondiffusible compounds for providing a transfer dye image are comprised of a spectral sensitizing dye moiety and a diffusible image dye moiety joined to a linkage in the spectral sensitizing dye moiety which is cleaved upon absorption of radiation by the spectal sensitizing dye moiety, thereby releasing the diffusible dye. Such compounds are useful in radiation-sensitive elements and processes.
