Method of stabilizing color photographic materials and a color photographic material

Claim 2

A process of stabilizing a photographic material containing a support layer, at least one hydrophilic layer of binder and at least one dye image by development of an exposed light-sensitive colour photographic material and treatment in an aftertreatment bath, wherein the aftertreatment bath contains a water-soluble compound corresponding to at least one of the following compounds I, II or III: ##STR34## in which R represents hydrogen or alkyl R 1 represents hydrogen or alkyl R 2 represents alkyl, cycloalkyl, aralkyl or aryl; R 3 represents a divalent hydrocarbon group; R 4 and R 5 , which may be the same or different, represent hydrogen or alkyl R 6 represents alkyl, cycloalkyl, aralkyl or aryl and/or R 1 and R 2 together represent the atoms required to complete a heterocyclic ring and/or R 3 together with R 4 and optionally also with R 5 represent the atoms required to complete a heterocyclic ring.

Claim 3

The process according to claim 1 wherein R represents hydrogen or an alkyl group with not more than 3 carbon atoms; R 1 represents hydrogen or an alkyl group with not more than 5 carbon atoms; R 2 represents an alkyl group with more than 4 carbon atoms; a cycloalkyl group; an aralkyl group with not more than 2 carbon atoms in the aliphatic moiety and 6 carbon atoms in the aromatic moiety; or an aryl group; R 3 represents an alkylene group with not more than 6 carbon atoms; R 4 and R 5 which may be the same or different represent hydrogen or an alkyl group with not more than 3 carbon atoms; R 6 represents an alkyl group with not more than 6 carbon atoms; cyclopentyl or cyclohexyl with 5 or 6 carbon atoms; an aralkyl group with not more than 2 carbon atoms in the aliphatic moiety and 6 carbon atoms in the aromatic moiety; or phenyl; and/or R 1 and R 2 may together represent the atoms required to complete a heterocyclic ring and/or R 3 together with R 4 and optionally also R 5 represent the atoms required to complete a heterocyclic ring.

Claim 4

A color photographic material consisting of (a) a support layer and (b) at least one hydrophilic layer of binder containing a dye image, said material containing at least one compound corresponding to one of the following compounds I-III: ##STR35## in which R represents hydrogen or an alkyl group with not more than 3 carbon atoms; R 1 represents hydrogen or an alkyl group with not more than 5 carbon atoms; R 2 represents an alkyl group with not more than 4 carbon atoms; a cycloalkyl group with 5 or 6 carbon atoms; an aralkyl group with not more than 2 carbon atoms in the aliphatic moiety and 6 carbon atoms in the aromatic moiety or a phenyl group; R 3 represents an alkylene group with not more than 6 carbon atoms, or a phenyl group; R 4 and R 5 which may be the same or different represent hydrogen or an alkyl group, in particular with not more than 3 carbon atoms, specifically methyl, ethyl or propyl; R 6 represents an alkyl group with not more than 6 carbon atoms; a cycloalkyl group with 5 or 6 atoms; an aralkyl group with not more than 2 carbon atoms in the aliphatic moiety and 6 carbon atoms in the aromatic moiety; or a phenyl group, and/or R 1 and R 2 may together represent the atoms required to complete a heterocyclic ring and/or R 3 together with R 4 and optionally also R 5 represent the atoms required to complete a heterocyclic ring.

Claim 5

A color photographic material consisting of (a) a support layer and (b) at least one hydrophilic layer of binder containing a dye image, said material containing at least one compound corresponding to one of the following compounds I-III: ##STR35## in which R represents hydrogen or an alkyl group with not more than 3 carbon atoms; R 1 represents hydrogen or an alkyl group with not more than 5 carbon atoms; R 2 represents an alkyl group with not more than 4 carbon atoms; a cycloalkyl group with 5 or 6 carbon atoms; an aralkyl group with not more than 2 carbon atoms in the aliphatic moiety and 6 carbon atoms in the aromatic moiety or a phenyl group; R 3 represents an alkylene group with not more than 6 carbon atoms, or a phenyl group; R 4 and R 5 which may be the same or different represent hydrogen or an alkyl group, in particular with not more than 3 carbon atoms, specifically methyl, ethyl or propyl; R 6 represents an alkyl group with not more than 6 carbon atoms; a cycloalkyl group with 5 or 6 atoms; an aralkyl group with not more than 2 carbon atoms in the aliphatic moiety and 6 carbon atoms in the aromatic moiety; or a phenyl group, and/or R 1 and R 2 may together represent the atoms required to complete a heterocyclic ring and/or R 3 together with R 4 and optionally also R 5 represent the atoms required to complete a heterocyclic ring.
