Abstract
5-PYRAZOLONE COLOR COUPLERS ARE INCORPORATED IN ALDEHYDE FOREHARDENED COLOR PHOTOGRAPHIC EMULSIONS AS ENOL ESTERS OF CARBOXYLIC AND SULFONIC ACIDS TO PREVENT REACTION OF 5-PYRAZOLONE WITH ALDEHYDE FOREHARDENING AGENT. A METHOD IS ALSO PROVIDED FOR THE CONVERSION OF THE ENOL ESTER TO THE FREE 5-PYRAZOLONE IN ORDER THAT IT CAN COUPLE WITH OXIDIZED COLOR DEVELOPER WHICH COMPRISES TREATING THE 5-PYRAZOLONE ENOL ESTER WITH AN ALKALINE SOLUTION CONTAINING AT LEAST ONE ORGANIC AMINE PRIOR TO OR CONCURRENT WITH COLOR DEVELOPMENT. ENOL ESTERS USEFUL WITHIN THE SCOPE OF THIS INVENTION ARE ILLUSTRATED BY THE GENERAL FORMULAE:
