Definitions

  • This invention relates to photographic materials and processes which utilize a compound capable of releasing a bleach accelerator moiety.
  • Photographic materials useful for forming dye images by means of a process which includes a bleaching step are known and used commercially. Such materials and processes are described in, for example. The Theory of the Photographic Process , 4th Edition, Edited by T. H. James, 1977, pages 462-463 and pages 335-361. The use in such photographic materials of a bleach accelerator releasing coupler is described in Research Disclosure , 1973, Item No. 11449.
  • the bleach accelerator releasing coupler also known as a BARC, has contained a heterocyclic group as the bleach accelerator moiety which is released during processing of the photographic element. These bleach accelerator releasing couplers cause an undesired degree of adverse development effects.
  • Couplers which have a thioether group at the coupling position have been known in the photographic art. Examples of such couplers are described in, for example, U.S. Patent 4,387,159, Japanese Published Patent Application 57-173836, U.S. Patent 3,227,554 and U.S. Patent 4,293,691. These compounds have been useful as development inhibitor releasing (DIR) couplers. Almost all of the couplers that are designed as development inhibitor releasing couplers have a thioether group and are oleophilic in order to help maintain the coupler in one location in the hydrophilic emulsion layers of the photographic material. Typically such couplers have ballast groups for this purpose. These have not required a balance of a strong affinity for silver and a balance of water solubility as is the case with bleach accelerator compounds.
  • DIR development inhibitor releasing
  • the present invention provides use of a coupler comprising a coupler moiety having a releasable bleach accelerator moiety represented by the formula: -(TIME) n -S-R1-R2 wherein TIME is a timing group; n is 0 or 1; R1 is a linking group consisting of alkylene comprising 1 to 8 carbon atoms; and, R2 is a water solubilizing group, as a bleach accelerator releasing coupler in a photographic element comprising a support, a photographic silver halide emulsion layer and the bleach accelerator releasing coupler incorporated in the emulsion layer or a layer adjacent thereto.
  • TIME is a timing group
  • n is 0 or 1
  • R1 is a linking group consisting of alkylene comprising 1 to 8 carbon atoms
  • R2 is a water solubilizing group
  • the releasable bleach accelerator moiety is in a location on the compound carrying the moiety which enables release of the bleach accelerator moiety at time during processing of the photographic element which enables acceleration of the bleaching step.
  • the bleach accelerator releasing compound is preferably a coupler having the bleach accelerator moiety in the coupling position.
  • the coupler can be, but need not be, a dye-forming coupler.
  • One embodiment of the invention is a silver halide photographic element containing a bleach accelerator releasing compound which has a releasable bleach accelerator moiety as described.
  • Coupler refers to the entire compound including the coupler moiety and the bleach accelerator moiety (TIME) n -S-R1-R2.
  • TIME bleach accelerator moiety
  • coupler moiety refers to that portion of the compound other than the bleach accelerator moiety.
  • the particular R1 group linking the sulfur atom and the water solubilizing group R2 can be varied to control such parameters as water solubility, diffusivity, silver affinity, silver ion complex solubility, silver development effects and other sensitometric effects. Since these parameters can be controlled by modification of R1, they need not be emphasized in selecting a particular coupler moiety and the particular water solubilizing group, but provide freedom in selecting such moieties and groups for a particular photographic element and process.
  • the bleach accelerator fragment is released at an appropriate time as a unit. That is, -S-R1-R2 is released as a unit.
  • the rate and total time of difussion of the bleach accelerator fragment in the photographic element must be such as to enable bleach acceleration in the appropriate layers of the photographic element during processing.
  • the timing group when present, also releases -S-R1-R2 as a unit.
  • Selection of R1 and R2 can also influence the rate and total time of release of the bleach accelerator moiety from the remainder of the compound, preferably the remainder of the coupler. It is necessary that the bleach accelerator moiety not adversely effect the processing steps and the photographic element.
  • Preferred photographic couplers used in the invention are represented by the formula: wherein COUP is a coupler moiety; m is 1 to 8; R3 and R4 are individually hydrogen or alkyl containing 1 to 4 carbon atoms; and wherein the total number of carbon atoms in is 1 to 8.
  • Alkyl includes straight or branched chain alkyl, such as methyl, ethyl, n-propyl, i-propyl, n-butyl, and t-butyl.
  • the coupler moiety can be any moiety that will react with oxidized color developing agent to enable release of the bleach accelerator moiety.
  • the coupler moiety includes coupler moieties which are useful in conventional dye-forming couplers whrch yield dyes on reaction with oxidized color developing agents as well as coupler moieties which yield colorless products on reaction with oxidized color developing agents.
  • the coupler moiety can be unballasted or ballasted with an oil-soluble group. It can be monomeric, or it can form part of a dimeric, oligomeric or polymeric coupler, in which case more than one bleach accelerator moiety can be contained in the coupler. Each coupling position can release a bleach accelerator moiety.
  • the reaction product of the coupler moiety and oxidized color developing agent can be: (1) colored and nondiffusible, in which case it will remain in the location where it is formed; (2) colored and diffusible, in which case it may be removed during processing from the location where it is formed or allowed to migrate to a different location; or (3) colorless and diffusible or nondiffusible, in which case it will not contribute to image density.
  • the reaction product may be initially colored and/or nondiffusible but converted to colorless and/or diffusible products during the course of processing.
  • the bleach accelerator moiety is attached at the coupling position of the coupler moiety which enables the bleach accelerator moiety to be displaced upon reaction of the coupler with oxidized color developing agent.
  • the bleach accelerator moiety can be bonded to the remainder of the organic compound through a timing group (TIME).
  • TIME in the described structures is a group which enables the time release of -S-R1-R2 from COUP.
  • the timing mechanism can be any timing mechanism which is useful for releasing photographically useful groups from coupler moieties.
  • the timing mechanism can be as described in, for example U.S. Patent 4,248,962 or U.S. 4,409,323.
  • Release of the bleach accelerator moiety can involve a single reaction or it can involve sequential reactions. For example, two or more sequential reactions may be required within a TIME group to effect release of the bleach accelerator moiety.
  • the TIME group can have two bleach accelerator moieties bonded to different locations on the TIME group so that upon release of the TIME group from the coupler moiety two reactions can occur sequentially enabling sequential release of the two bleach accelerator moieties.
  • Another example is a reaction in the TIME group which may release a second coupler moiety which contains another timing group to which a photographically useful group is attached and from which it is released after the second coupler moiety reacts with oxidized color developing agent.
  • the TIME group can contain moieties and substituents which will permit control of one or more of the rates of reaction of COUP with oxidized color developing agent, the rate of diffusion of -TIME-S-R1-R2 once it is released from COUP and the rate of release of -S-R1-R2.
  • the TIME group can contain added substituents, such as added photographically useful groups which can remain attached to the timing group and be released independently.
  • the TIME groups can contain a ballast group.
  • R2 groups are examples of useful water solubilizing groups wherein R5 is H or alkyl of 1 to 4 carbons, R6 is alkyl of 1 to 4 carbons and wherein at least one of R5 and R6 is alkyl, and the total carbon atoms in R5 and R6 is no more than 8.
  • couplers are phenols and naphthols which form cyan dyes on reaction with oxidized color developing agents and have the releasable bleach accelerator moiety attached at the coupling position, that is the carbon atom in the 4-position of the coupler moiety.
  • R8, R9, R10, R11 and R12 individually represent ballast groups; R7 and R9, individually represent at least one halogen atom, such as chloro or fluoro; alkyl, such as alkyl containing 1 to 4 carbon atoms, for example methyl, ethyl, propyl or butyl; or alkoxy, such as alkoxy containing 1 to 4 carbon atoms, for example methoxy, ethoxy, propoxy and butoxy.
  • magenta dye-forming couplers are pyrazolones and pyrazolotriazoles which form magenta dyes upon reaction with oxidized color developing agents.
  • Structures of preferred magenta dye-forming couplers are: wherein R14, R16 and R17 are individually aryl, alkyl, such as alkyl containing 1 to 30 carbon atoms; and R13, R15 and R18 are individually ballast groups, or are phenyl or substituted phenyl, such as 2,4,6-trihalophenyl, for example 2,4,6-trichlorophenyl.
