Patent number: 5411856Abstract: Novel compounds represented by formula (I) ##STR1## wherein R.sub.1 and R.sub.2 represent hydrogen or alkyl, R.sub.3 represents hydrogen, alkyl, substituted alkyl or CONR.sub.1 R.sub.2, and n is 0 to 6, can be used to harden gelatin. The compounds are particularly useful for hardening gelatin of a photographic element.Type: GrantFiled: January 10, 1994Date of Patent: May 2, 1995Assignee: Eastman Kodak CompanyInventors: Edgar E. Riecke, Kenneth G. Harbison

Patent number: 5316902Abstract: Hydrophilic organic colloids such as collagen or gelatin are modified for use in photographic elements such as film or paper, or for use as reagents in automated dry chemical analyzers. The modification comprises reaction of some of the carboxy groups attached to the polypeptide with (i) a amide bond forming agent, e.g. 1-pyrrolidinylcarbonylpyridinium chloride, and (ii) a di- or triamine, such as piperazine, diethylenetriamine or ethylenediamine. Such modification enables that colloid to react faster with a gelatin hardener such as bis(vinylsulfonyl)methane (BVSM). When coated over an equal amount of unmodified gelatin, and both layers imbibed with BVSM, a modified gelatin layer showed an enzyme resistance greater than that of the unmodified gelatin. This demonstrates that the modified gelatin hardened preferentially.Type: GrantFiled: January 4, 1993Date of Patent: May 31, 1994Assignee: Eastman Kodak CompanyInventors: Donald P. Specht, Kenneth G. Harbison

Patent number: 5236822Abstract: A method for hardening gelatin which comprises using as a hardening agent a compound represented by formula (I): ##STR1## wherein R.sub.1, when taken along, may be alkyl of 1 to 20 carbon atoms, aralkyl of from 7 to 20 carbon atoms, aryl of from 6 to 20 carbon atoms, and alkenyl of from 2 to 20 carbon atoms. R.sub.1 and R.sub.2 can also combine with each other to form a heterocyclic ring of 5 to 8 atoms. The R.sub.1 -R.sub.2 ring contains the nitrogen atoms to which R.sub.1 and R.sub.2 are attached, and may also contain an additional nitrogen atom. R.sub.2 and R.sub.3 can combine to form either a 5 or 6 membered ring. The R.sub.2 -R.sub.3 ring contains the nitrogen atom to which R.sub.2 is attached, and may also contain one or two additional nitrogen atoms. R.sub.4 may be hydrogen or alkyl of 1 to 4 carbon atoms.
