| abstract | Disclosed are novel antifoggant precursors having the general formula (I) or (II) which are sufficiently stable in a wealkyl acidic medium, are markedly effective in restraining over-development fog and besides cause little loss of sensitivity: <IMAGE> (I) (wherein Y represents oxygen atom or <IMAGE> X represents OR3 when Y is oxygen atom and R3 when Y is <IMAGE> where R1 and R2 each represents hydrogen atom, alkyl group aryl group and R3 represents hydrogen atom, alkyl group or phenyl group; R4-R6 each represent hydrogen atom, halogen atom, alkyl group, carboxyl group, alkoxycarbonyl group or phenyl group, R4 and R5 may form together a benzene ring; R7 represents hydrogen atom, alkyl group or phenyl group; and A represents a heterocyclic group of the mercapto antifoggant.) <IMAGE> (II) (wherein X, Y, R4-R5 and A are the same as defined for the general formula (I) and R4 and R5 or R5 and R6 may form together a benzene ring.). |
