Definitions

  • Multicolour elements contain dye image-forming units sensitive to each of the three primary regions of the spectrum. Each unit can be comprised of a single emulsion layer or of multiple emulsion layers sensitive to a given region of the spectrum.
  • the layers of the element, including the layers of the image-forming units, can be arranged in various orders as known in the art.
  • a typical multicolour photographic element comprises a support bearing yellow, magenta and cyan dye
  • imidazotriazole couplers in accordance with the present invention can be prepared in high yields from inexpensive starting materials in only six or seven nominal steps.
  • the method of producing the basic imidazotriazole ring system is shown in the following reaction scheme 1. Scheme 1.
  • R 1 optionally substituted aryl

Abstract

Nouveau copulant magenta répondant à la formule (I), dans laquelle R1 et R2 sont identiques ou différents et représentent H, alkyle, alkyle substitué, aryle, aryle substitué, hétéroaryle, alkylthio, ester ou acide carboxylique, amido primaire ou secondaire, sulfonamido, amino mono- ou disubstitué, alcoxy ou aryloxy; et X représente H ou un groupe pouvant être libéré lors d'un couplage par oxydation à un agent de couplage de couleurs. Ces copulants magenta ne présentent aucun pouvoir tinctorial secondaire dans la région bleue du spectre, ce qui entraîne une amélioration du rendu des couleurs, et peuvent être synthétisés de manière simple et peu coûteuse.
