Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
198 words
Light sensitive photographic material comprising a support layer and at least one hydrophilic layer of binder containing a colour coupler for producing a dye image, wherein the material contains in an emulsified form at least one of the following compounds, I, II or III, which are insoluble in alkali solutions, ##STR31## in which R represents hydrogen or an alkyl group; R 1 represents hydrogen or an alkyl, cycloalkyl, aralkyl or aryl group; R 2 represents an alkyl, cycloalkyl, aralkyl or aryl group; R 3 represents a divalent hydrocarbon group; R 4 , R 5 which may be the same or different represent hydrogen or an alkyl group; R 6 represents an alkyl with 7 to 11 carbon atoms, cycloalkyl, aralkyl or aryl 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 R 5 may represent the atoms required to complete a heterocyclic ring, under the condition that when R 1 and R 2 together form a heterocyclic ring, this has at least 7 carbon atoms and that otherwise R 1 and R 2 together have at least 10 carbon atoms.
Claim 2
Dependent Claim
198 words
Light sensitive photographic material comprising a support layer and at least one hydrophilic layer of binder containing a colour coupler for producing a dye image, wherein the material contains in an emulsified form at least one of the following compounds, I, II or III, which are insoluble in alkali solutions, ##STR31## in which R represents hydrogen or an alkyl group; R 1 represents hydrogen or an alkyl, cycloalkyl, aralkyl or aryl group; R 2 represents an alkyl, cycloalkyl, aralkyl or aryl group; R 3 represents a divalent hydrocarbon group; R 4 , R 5 which may be the same or different represent hydrogen or an alkyl group; R 6 represents an alkyl with 7 to 11 carbon atoms, cycloalkyl, aralkyl or aryl 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 R 5 may represent the atoms required to complete a heterocyclic ring, under the condition that when R 1 and R 2 together form a heterocyclic ring, this has at least 7 carbon atoms and that otherwise R 1 and R 2 together have at least 10 carbon atoms.
Claim 3
Dependent Claim
191 words
Color photographic image comprising a support layer and at least one hydrophilic layer of binder containing a dye image, wherein the image contains in an emulsified form at least one of the compounds I, II or III, which are insoluble in alkali solutions ##STR32## in which R represents hydrogen or an alkyl group; R 1 represents hydrogen or an alkyl, cycloalkyl, aralkyl or aryl group; R 2 represents an alkyl, cycloalkyl, aralkyl or aryl group; R 3 represents a divalent hydrocarbon group; R 4 , R 5 which may be the same or different represent hydrogen or an alkyl group; R 6 represents an alkyl with 7 to 11 carbon atoms, cycloalkyl, aralkyl or aryl 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 R 5 may represent the atoms required to complete a heterocyclic ring, under the condition that when R 1 and R 2 together form a heterocyclic ring, this has at least 7 carbon atoms and that otherwise R 1 and R 2 together have at least 10 carbon atoms.
Claim 4
Dependent Claim
191 words
Color photographic image comprising a support layer and at least one hydrophilic layer of binder containing a dye image, wherein the image contains in an emulsified form at least one of the compounds I, II or III, which are insoluble in alkali solutions ##STR32## in which R represents hydrogen or an alkyl group; R 1 represents hydrogen or an alkyl, cycloalkyl, aralkyl or aryl group; R 2 represents an alkyl, cycloalkyl, aralkyl or aryl group; R 3 represents a divalent hydrocarbon group; R 4 , R 5 which may be the same or different represent hydrogen or an alkyl group; R 6 represents an alkyl with 7 to 11 carbon atoms, cycloalkyl, aralkyl or aryl 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 R 5 may represent the atoms required to complete a heterocyclic ring, under the condition that when R 1 and R 2 together form a heterocyclic ring, this has at least 7 carbon atoms and that otherwise R 1 and R 2 together have at least 10 carbon atoms.
