    摘要： Photographic elements, film units, processes and alkaline processing compositions are described wherein certain 4-hydroxyalkyl-substituted 3-pyrazolidinones are employed as electron transfer agents in black-and-white and color image transfer materials. The silver halide electron transfer agents or precursors thereof have the following formula: ##STR1## wherein: n is 1 or 2;R repesents hydrogen or a hydrolyzable moiety;R.sup.1 represents an alkyl or substituted alkyl group of 1 to about 6 carbon atoms, an aryl or substituted aryl group of 6 to about 10 carbon atoms, or an aralkyl group of 6 to about 10 carbon atoms;R.sup.2 and R.sup.3 each independently represents hydrogen, an alkyl or substituted alkyl group of 1 to about 6 carbon atoms, an aryl or substituted aryl group of 6 to about 10 carbon atoms, or an aralkyl group of 6 to about 10 carbon atoms; andR.sup.4 represents hydrogen or one or more alkyl or alkoxy groups having from 1 to about 4 carbon atoms, methylenedioxy groups or ethylenedioxy groups.
