Abstract
Abstract As mordant for mordanting diffusing anionic dyes in image receiving layers of photographic dye diffusion materials the invention makes use of addition polymers having at least 10 mole % of recurring structural units of formula I ##STR1## in which Q represents nitrogen or phosphorus; R 1 , R 2 , R 3 each represents a carbocyclic or alkyl group or two of these substituents complete a 5- or 6-membered heterocyclic ring R 4 represents hydrogen or alkyl, X⊖ is an anion.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
140 words
A photographic material comprising a layer support having coated thereon at least one image-receiving layer which contains a polymeric mordant for acidic dyes, in which the polymeric mordant is a polymer obtained by addition polymerisation of a mixture of monomers containing at least 10 mole % of a monomer that on addition polymerisation provides recurring structural units of formula I in which Q is a nitrogen or phosphorus atom; R 1 , R 2 and R 3 are the same or different and represent alkyl radicals of 1 to 12 carbon atoms or carbocyclic radicals selected from the group consisting of cycloalkyl, aralkyl and aryl radicals or two of the substituents R 1 , R 2 and R 3 together with the Q complete a 5- or 6-membered heterocyclic ring. R 4 represents hydrogen or methyl X.sup.⊖ represents an anion.
Claim 2
Dependent Claim
140 words
A photographic material comprising a layer support having coated thereon at least one image-receiving layer which contains a polymeric mordant for acidic dyes, in which the polymeric mordant is a polymer obtained by addition polymerisation of a mixture of monomers containing at least 10 mole % of a monomer that on addition polymerisation provides recurring structural units of formula I in which Q is a nitrogen or phosphorus atom; R 1 , R 2 and R 3 are the same or different and represent alkyl radicals of 1 to 12 carbon atoms or carbocyclic radicals selected from the group consisting of cycloalkyl, aralkyl and aryl radicals or two of the substituents R 1 , R 2 and R 3 together with the Q complete a 5- or 6-membered heterocyclic ring. R 4 represents hydrogen or methyl X.sup.⊖ represents an anion.
Claim 3
Dependent Claim
29 words
A photographic material as claimed in claim 1 in which R 1 , R 2 and R 3 are the same or different and represent methyl, ethyl or benzyl.
Claim 4
Dependent Claim
30 words
A photographic material as claimed in claim 1 in which the image-receiving layer which contains the polymeric mordant contains also mordanted therein one or more acidic dyes in image distribution.
Claim 5
Dependent Claim
39 words
A photographic material as claimed in claim 1 having in contact with the image-receiving layer a light sensitive recording element comprising at least one light sensitive silver halide emulsion layer and associated thereto in uniform distribution a color-providing compound.
