Definitions

  • This invention relates to photographic silver halide processing solutions and particularly to colour developing solutions.
  • US Patent 4 155 763 describes colour developing solutions comprising an aromatic amine colour developing agent and a 1-aryl-pyrazolidone having two substituents at the 4-position of the pyrazolidon .
  • the advantages are said to include faster image dye formation and a more stable colour developing solution.
  • a useful group of Type (1) ETA's of formula (I) are those in which at least one of R 1 and/or R 2 is an alkoxy group of 1-4 carbon atoms, eg -OCH3, 3 is hydrogen or an alkyl group of 1-4 carbon atoms, eg - CH3 and R ⁇ is hydrogen or a hydroxyalkyl group of 1-4 carbon atoms, eg -CH2OH.
  • the preferred black-and-white developers are: 1- (4-methoxyphenyl)-3-pyrazolidone, l-(3,4-dimethoxy- phenyl)-3-pyrazolidone, and l-phenyl-4-n-pentyl- pyrazolidone.
  • the black-and-white developing agent may be present in the developer solution at a concentration up to 5 g/1 preferably in the range 0.05 to 0.5 g/1.
  • concentration up to 5 g/1 preferably in the range 0.05 to 0.5 g/1.
  • incorporated in the photographic material it may be present in one or more layers thereof. Instead of incorporating them per se in the photographic material they may be, as indicated above, in the form of a
  • the present invention is particularly applicable to the processing of colour negative film but is also applicable to other processes, eg colour paper.
  • the material to be processed comprises a support bearing at least one silver halide emulsion layer having a colour coupler associated therewith.
  • the term "associated therewith” here takes its normal meaning in art.
  • the coupler may be incorporated in the emulsion layer or in a layer adjacent thereto.
  • the preferred colour materials comprise three dye image forming units each containing one or more emulsion layers having couplers associated therewith and each sensitised to a different region of the spectrum.
  • a typical colour material would contain such units sensitised to blue, green and red light and capable of forming yellow, magenta and cyan image dyes respectively.
  • a single layer coating of a silver bromoiodide emulsion comprising tabular grains having a mean grain area of 1.05 m ⁇ 2 containing a colour coupler (A) of the formula:
  • OC 12 H 25 dissolved in di-tert-butylphthalate (coupler to solvent ratio of 1:0.5) was coated at 1.0 g/m 2 (as silver) and 0.6 g/m 2 of coupler.
  • Table 1 below gives process details of concentration of l-(4-methoxyphenyl)-3-pyrazolidone and development time at 37.8°C.
  • EXAMPLE 3 A single layer coating of a silver bromoiodide emulsion as described in Example 1 was tested by the procedure of Example 1 was followed except that the time of development was kept constant at 2.5 minutes while varying the CD4 and ETA concentrations as set out in Table 2 below.

Abstract

Procédé de développement d'un matériau en couleurs à base d'halogénure d'argent comportant une image latente, afin d'obtenir des résultats sensitométriques acceptables à variabilité réduite. Ledit procédé consiste à réaliser un développement en couleurs en présence d'un agent de développement réversal en noir et blanc, ou d'une combinaison de ces agents, ce qui réduit la variabilité des résultats sensitométriques due aux modifications des variables du processus. Il s'agit de préférence du 1-(4-méthoxyphényl)-3-pyrazolidone, du 1-(3,4-diméthoxy-phényl)-3-pyrazolidone, ou du 1-phényl-4-n-pentyl-pyrazolidone.
