More Information
Summary:Colour photography material with light sensitive silver halogens including a support with at least one layer of silver halogen emulsion containing a mix, that frees a photographically useful group, represented by formula (1):where n represents 1 or 2 (based on when n is 2, r can be the same or different), R is a hydrogen atom or a halogen, a hydroxyl group, nitrogen, alkaline, alkyl oxycarbon, aryl oxycarbon, alcohols, aryl oxides, alkyl carbon, aryl carbon, alkyl oxides, alkyl sulphur, aryl sulphur, acyl, acylamino, sulphuramino, sulphuramide, or rather a cyclical group represented by:where x is an alkyl group, PUG is a photographically useful group, Z represents the atoms necessary to complete a heterocyclic ring with 7 terminals containing nitrogen, a -NR1-CO- group or rather agroup where z represents the necessary atoms to form the heterocyclic ring with 5 or 6 terminals containing nitrogen, and R1 is a hydrogen atom, an aryl or heterocyclic group.
