摘要： A silver halide photographic material for obtaining silver images is described, comprising at least one silver halide emulsion layer on a support having a white reflection layer, wherein at least one compound represented by formula (I) is contained in at least one of the constituent layers: ##STR1## wherein X.sup.1 represents a divalent bonding group bonded by way of a hetero atom to a carbon atom; A represents a group capable of controlling the tone of silver images, which is bonded to X.sup.1 by way of the hetero atom of A; R.sup.1, R.sup.2 and R.sup.3 each represents a hydrogen atom or a group that can be substituted, in which R.sup.1 and R.sup.2, or R.sup.1 and R.sup.3 may further be bonded together to form a carbocyclic ring or a heterocyclic ring; Y represents: ##STR2## a cyano group or a nitro group, in which R.sup.4, R.sup.5, R.sup.6, R.sup.7 R.sup.8 may each represent a hydrogen atom or a group that can be substituted; n and m represent 0 or 1, provided that if m is 0, the group represented by A is bonded to a carbon atom by way of the hetero atom of A.
