| titleOfInvention | Improvements in or relating to photographic materials, especially for imbibition printing |
| abstract | The following polymeric materials are disclosed for use as mordants in photographic dye transfer materials (see Divisions G2-G3):- (a) Reaction products of an N,N-disubstituted alkylene diamine and a polymer containing mobile halogen or repeated 1,2-epoxy groups or of a haloalkylamine and a polymer containing tertiary amino groups. These have groups <FORM:1022206/C3/1> bound to some or all the monomeric units. (b) Reaction products of a compound of the formula <FORM:1022206/C3/2> and a halogen- or epoxy group-containing polymer as above. These have groups <FORM:1022206/C3/3> bound to some or all the monomeric units. (c) Reaction products of a halo-alkylamine and a polymeric heterocyclic amine. These have groups <FORM:1022206/C3/4> bound to some or all the monomeric units. (d) Reaction products of a monomer containing a quaternary or quarternizable nitrogen atom and a comonomer containing a primary amino group all of which have been rendered insoluble by a hardener which forms cross-links between primary amino groups. In the above formulae R and R1 are each alkyl, aryl or aryl-alkyl groups or together complete a 5 or 6 membered heterocyclic ring, R11 is a divalent aliphatic group, Y is H, alkyl or a condensed aromatic ring, Y11 is a divalent saturated aliphatic group, a single valency bond or a condensed aromatic ring, - - - Z - - - represents carbon atoms completing a 5 or 6 membered ring and X- is the anion of an inorganic or organic acid. The halogen-containing polymers may be obtained by treating polymers of styrene or phenol or naphthol-aldehyde resins with monochloromethyl ether in the presence of zinc chloride. Specified epoxy polymers are homo- and copolymers of allyl glycidyl ether; glycidyl acrylate, methacrylate and rotonate; and butadiene and vinylcyclohexene monoxides. Specified t-amino polymers for (a) are homo- and co-polymers of N,N-dialkylaminoalkyl-acrylates, -methacrylates, -acrylamides and -methacrylamides while specified polymeric t-amine for (c) are polymers of 2-methyl-5 vinylpyridine. Suitable N reactants for (a) and (b) are also specified. Cross links between the NH2 groups may be obtained by treatment with aldehydes, dialdehydes, polyaldehydes, di- and poly-epoxides, and dimethylolurea. |
