| titleOfInvention | 4-Hydroxyalkyl-substituted 3-pyrazolidinone electron transfer agents |
| abstract | 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: <IMAGE> wherein: n is 0, 1 or 2; R represents hydrogen or a hydrolyzable moiety; R1 and R2 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, with the proviso that when n is 0, then either R1 or R2, but not both, may be hydrogen; and R3 represents at least one alkyl or alkoxy group having from 1 to about 6 carbon atoms, methylenedioxy group or ethylenedioxy group. |
