Abstract

A silver halide photographic material composed of a support having thereon at least one light-sensitive silver halide emulsion layer, wherein the material contains the combination of (i) at least one compound represented by formula (I) and (ii) and at least one compound represented by formulae (II) and/or (III): ##STR1## wherein R.sub.1 represents hydrogen, an alkyl group, an aryl group or an aralkyl group; X represents a halogen atom, a nitro group, a hydroxyl group, a cyano group, a lower alkyl group, a lower alkoxy group, --COR.sub.2, ##STR2## or --SO.sub.3 M; R.sub.2 represents hydrogen, --OM, a lower alkyl group, an aryl group, an aralkyl group, a lower alkoxy group, an aryloxy group, an aralkyloxy group or ##STR3## R.sub.3 and R.sub.4 each represents hydrogen, a lower alkyl group, an aryl group, an aralkyl group, --COR.sub.7 or --SO.sub.2 R.sub.7 ; R.sub.5 and R.sub.6 each represents hydrogen, a lower alkyl group, an aryl group or an aralkyl group; R.sub.7 represents a lower alkyl group, an aryl group or an aralkyl group, M represents hydrogen, an alkali metal atom or atoms necessary for forming a monovalent cation, m represents 0 or an integer of 1 to 4, n represents 0 or an integer of 1 to 4, and Z represents an atomic group necessary for forming a thiazolyl ring; ##STR4## where in R.sub.8 represents a lower alkylene group, X is the same as X in formula (I), p represents 0 or 1, and q represents 0 or an integer of 1 to 5; ##STR5## wherein R.sub.9 represents hydrogen, an alkyl group, an alkenyl group, an aralkyl group, an aryl group, a heterocyclic group, ##STR6## R.sub.10 and R.sub.11 each represents hydrogen, an alkyl group, an aryl group, a cyano group, a heterocyclic group, an alkylthio group, an arylthio group, an alkylsulfonyloxy group or an alkylsulfonyl group; R.sub.10 and R.sub.11 may be linked to form an aromatic ring; and R.sub.12 and R.sub.13 each represents hydrogen, an alkyl group, an aryl group or an aralkyl group. The material has superior antifungal and antibacterial properties.

A silver halide photographic material comprising a support having thereof at least one light-sensitive silver halide emulsion layer, wherein said material contains the combination of (i) at least one compound represented by formula (I) added to a protective layer and (ii) at least one compound represented by formulae (II) and/or (III) added to a protective layer, an interlayer, a filter layer or an antihalation layer ##STR22## wherein R.sub.1 represents hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted aralkyl group;

X represents a halogen atom, a nitro group, a hydroxyl group, a cyano group, a lower alkyl group, a lower alkoxy group, --COR.sub.2, ##STR23## or --SO.sub.3 M;
R.sub.2 represents hydrogen, --OM, a lower alkyl group, an aryl group, an aralkyl group, a lower alkoxy group, an aryloxy group, an aralkyloxy group or ##STR24## R.sub.3 and R.sub.4, which may be the same or different, each represents hydrogen, a lower alkyl group, an aryl group, an aralkyl group, --COR.sub.7 or --SO.sub.2 R.sub.7 ;
R.sub.5 and R.sub.6, which may be the same or different, each represents hydrogen, a lower alkyl group, an aryl group or an aralkyl group;
R.sub.7 represents a lower alkyl group, an aryl group or an aralkyl group;
M represents hydrogen, an alkali metal atom or a monovalent cation;
m represents 0 or an integer of 1 to 4, n represents 0 or an integer of 1 to 4, and Z represents an atomic group necessary for forming a thiazolyl ring ##STR25## wherein R.sub.8 represents a lower alkylene group, X is the same as defined for X in formula (I);
p represents 0 or 1, and q represents 0 or an integer of 1 to 5;
and ##STR26## wherein R.sub.9 represents hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, a heterocyclic group, ##STR27## R.sub.10 and R.sub.11 each represents hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a cyano group, a heterocyclic group, a substituted or unsubstituted alkylthio group, a substituted or unsubstituted arylthio group, a substituted or unsubstituted alkylsulfonyloxy group or a substituted or unsubstituted alkylsulfonyl group;
R.sub.10 and R.sub.11 may be linked to form an aromatic ring;
and R.sub.12 and R.sub.13, which may be the same or different, each represents hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted aralkyl group.
