摘要:
Proteinaceous material such as gelatin is hardened by treatment with an aqueous solution of the partial hydrolysis product of a 2,4-dichloro-6-alkoxy-S-triazine with a water-soluble tertiary phosphate and/or a water-soluble borate, wherein the 2,4-dichloro-6-alkoxy-s-triazine corresponds to the formula: ##STR1## wherein R is a lower alkyl or alkoxyalkyl group. The proteinaceous material can be a proteinaceous coating such as a photographic silver halide emulsion layer, a backing layer, a protective layer, a filter layer, or any other photographic auxiliary layer.
摘要:
A proteinaceous material such as gelatin is hardened by treatment with an aqueous solution of a partial hydrolysis product of cyanuric chloride that has been buffered with a water-soluble borate, e.g. sodium metaborate, potassium metaborate or ammonium metaborate.The proteinaceous material can be a proteinaceous coating such as a photographic silver halide emulsion layer, a backing layer, a protective layer, a filter layer or any other photographic auxiliary layer.
摘要:
Color photographic material containing a fast-acting hardener, which acts by activating carboxyl groups, wherein said material contains a 2-pyrazolin-5-one coupler precursor corresponding to one of the following general formulae I or II: ##STR1## wherein EACH OF R.sup.1, R and Y are substituents of the type used in 2-pyrazolin-5-one color couplers, andZ represents acyl, alkoxycarbonyl, aryloxycarbonyl,Or ##STR2## in which R.sup.1, R, and Y have the above-defined significance, and A represents an alkylene group or an arylene group.
