Abstract

L'invention concerne de nouveaux coupleurs photographiques. Ces coupleurs, qui forment des colorants dont la sensibilité maximale est située entre 750 et 850 nm, sont des 1-hydroxy-2-naphtamide fluorés, substitués sur l'azote par un groupe alkylphénoxy-butyle. On peut les utiliser dans un produit photographique comprenant, dans la couche d'émulsion ou dans une couche adjacente, des particules de solution de coupleurs dans un solvant, tel que le phtalate dibutylique. Application à la formation de traces acoustiques, particulièrement dans des films cinématographiques, ces films pouvant être projetés grâce aux appareils de projection usuels.
