ABSTRACT:
A novel group of fluoroacetylphenyl hydrazines useful in insuring rapid-access processing of lithographic film elements is described. These hydrazines not only will produce good dot quality under conditions of rapid-access processing, but can be used a lower pH than conventional, prior art elements and will produce lower fog.
