Definitions

  • the invention relates to a new composition for revealing color photographs.
  • developer we use bodies reducing organic agents, generally cyclic, having at least two phenol groups (diphenol), or two amine groups (diamine) or these two groups (amino-phenol).
  • diphenol phenol groups
  • diamine amine groups
  • amino-phenol amino-phenol
  • CD chromogenic developer
  • EP 2 in which the developer is of the CD 3 type, for example a compound chosen from the group consisting of 4-amino-N-ethyl-N- ( ⁇ methylsulfonamidoethyl) -m-toluidine sesquisulfate monohydrate, phosphate of the same compound, N-ethyl-N- ( ⁇ -methylsulfonaminoethyl) -p-methyl-1-4-phenylene- diamine sesquisulfonate monohydrate or N-ethyl-N- (e methylsulfanimoethyl ) -p-toluenediamine.
  • This composition gives excellent results under current conditions of use and productivity for traditional development on paper.
  • CD 4 used for the development, no longer of the insulated papers, but for that of the photographic films themselves also in color.
  • CD 4 compounds give excellent results for the development of color photographic films.
  • these CD 4 products generally lead to results at best comparable to those obtained with CD-type developers. In short, these compounds are also limited in speed.
  • the invention overcomes these drawbacks. It relates to a developer for the development on paper of color photographs which enables the processing time to be reduced by almost half and thereby is compatible with the technical performance of the most modern automatic development equipment, without, however, the others. essential qualities of the photographs, such as the contrast, the chromatic balance, the veil are not appreciably affected.
  • the mixing of the various components is carried out in a known manner, gradually and under usual conditions, in order to ensure perfect missibility of the various constituents and to attenuate the toxic effects of some of them.
  • This composition is used to develop an impressed witness color paper. We operate at 40 ° C. After at least one hundred seconds of treatment, we obtain good chromatic balance, good density and good development.
  • Example 1 is repeated, replacing the CD 3 developer with a CD 4 type developer of general formula: 4-amino-3-methyl-N- (f, hydroxyethyl) -aniline sulfate also marketed by Hunt Chemicals for the development of films negative.
  • Example 1 is repeated by adding to the composition, at room temperature, one hundred and eighty five (185) grams of the same CD 4 developer as in Example 2.
  • the duration of the treatment is reduced from a hundred seconds to only fifty seconds, while retaining an excellent chromatic balance, good density and good contrast.
  • Example 3 is repeated, no longer adding 185 g, but one hundred and seventy (170) grams of the same compound CD 4 . After development and drying, a poor chromatic balance is obtained, with the blue-sensitive layer falling, which results in a crippling underdevelopment.
  • Example 3 is repeated, but using not 185 g of this CD 4 , but two hundred and thirty (230) grams of this compound. We also obtain a chromatic imbalance resulting from the rise of the blue color, which results in an overdevelopment also redhibitory.
