Abstract

Abstract A silver photosensitive material comprising a development inhibitor-releasing compound of the formula ##EQU1## wherein Z is an atomic group necessary to form a 5 to 7 membered saturated or unsaturated carbon ring with the carbon atoms to which it is attached, said ring being unsubstituted or substituted by at least one of halogen and a member of the class consisting of alkyl, aryl, alkoxy, acyloxy, aryloxy, SY and a group forming a condensed carbon ring with said saturated or unsaturated carbon ring; Y is arylmercapto, heterocyclic, thioglycollic acid, cystein or glutathione. A method for the development of silver halide photosensitive material by the use of the foregoing compound is also disclosed.
