Abstract
Novel compounds have been discovered that are particularly effective as nucleation accelerators or boosters when employed with hydrazide nucleators in the formulation of silver halide emulsions for lithographic film. The novel compounds contain bis ureido groups joined by an alkyleneoxy moiety or recurring alkyleneoxy moieties. The 2-nitrogen of each ureido group can carry groups comprising hydrogen, aryl, alkyl or dialkylaminoalkyl, alike or different.
