Definitions

  • One of-its objects is to provide new photographic developers of the para-phenylenediamine series. Further objects will be seen-from the detailed specification following hereafter.
  • Para-phenylenediamine is a known developer for silver halide emulsions. It is also known that wthe substitution products of developers of this class form, with suitable dyestuif "components, color pictures in the development. Substances suitable are described in UJS. Patent, 1 ,'102,028, dated June 30, 1914. Hitherto only'thederivatives of para-phenylenediamine whi'cii'are alkylated at the nitrogen atom have been used as color developers. All these bodies and especially the most suitable of them are, however, of only limited solubility in water or in a sodium carbonate solution.
  • This invention is based on the observation that valuable developing agents, particularly suitable for development in colors, may be obtained by introducing a sulfonlc or carboxylic group into a positive radical 'attachedto the nitrogen, so as to produce for example, paraamino-N-methyl-aniline-omega-sulfonic a c i d, para-amino-N-ethylaniline-omega-sulfonic acid. 4-amino-N-benzyl-aniline-4'-sulfonic acid, and so on.
  • a formula for the developers of this invention is the following:
  • the two groups of' developers may be. combined in accordance with the following formula:
  • NHI-HCI (7) 1 mol of the condensation product from 1 mol monoethyl-m-toluidine and 2 mols ethyleneoxide is treated in the same manner as described in Example 1. A compound of the following formula is obtained:
  • n is a whole number.
  • n is a whole number and a member selected from the group consisting of hydrogen.
  • alkyl aryl and aralkyl.
  • NHI-HCI 4 A photographic developer containing a p-phenyienediamine corresponding with the following formula CHEN-Clix.0H
  • NHsHCl 5 A photographic developer containing a p-phenylenediamine corresponding with the following formula NHaHCl GUSTAV WILMANNS.
