    • 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. R.sub.5 may be hydrogen or one or more substituents at any of positions 3 through 6 on the pyridine ring, including alkyl of 1 to 20 carbon atoms, aryl of from 6 to 20 carbon atoms, aralkyl of from 7 to 20 carbon atoms, or alkenyl of from 2 to 20 carbon atoms, alkoxy of 1 to 20 carbon atoms, aryloxy of from 6 to 20 carbon atoms, carboxy, halogen, nitro, or sulfo. R.sub.5 may be in a fused ring structure such as in quinoline. X.sup.- represents an anion or an anionic portion of compounds of formula (I) effectively harden gelatin with little or no afterhardening. These compounds are useful in hardening gelatin in photographic elements.

    • 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. This discovery of a method for differential hardening can be utilized to prepare multilayer photographic elements or multilayer reagents for chemical analyzers that contain one or more layers which are hardened preferentially, i.e. to a greater degree than other layers.
    • 亲水性有机胶体如胶原或明胶被修饰用于照相材料如薄膜或纸张,或用作自动干化学分析仪中的试剂。 修饰包括与多肽连接的一些羧基与(i)酰胺键形成剂,例如, 1-吡咯烷基羰基吡啶鎓氯化物,和(ii)二胺或三胺如哌嗪,二亚乙基三胺或乙二胺。 这种改性使得胶体与明胶固化剂如双(乙烯基磺酰基)甲烷(BVSM)反应更快。 当涂覆在等量的未改性明胶上,并且两层都被BVSM吸收时,改性明胶层显示出比未改性明胶更大的酶电阻。 这表明改性明胶优先硬化。 这种用于差分硬化的方法的发现可以用于制备用于化学分析仪的多层照相元件或多层试剂,所述多层照相元件或多层试剂含有一个或多个优先硬化的层,即比其它层更大的硬化层。
