Abstract
Disclosed is a silver halide photographic light-sensitive material having one or more layers including a light-sensitive silver halide emulsion layer on a support, wherein any of the layers contains the specific fluorine compound. The silver halide photographic light-sensitive material can be stably produced and is imparted with antistatic property.
Claims10
A fluorine compound represented by the following formula (1-b):
- wherein R13, R14 and R15 each independently represent a substituted or unsubstituted alkyl group and two or more of R13, R14 and R15 may be taken together with the nitrogen atom to which R13, R14 and R15 bond to form a ring;
- Z represents a divalent bridging group, and A and B each represents a fluorine atom or a hydrogen atom;
- n1 represents an integer of 1-6 and n2 represents an integer of 3-6;
- Y− represents a counter anion, but Y− may not be present when the intramolecular charge excluding Y− is 0;
- and m is 0 or 1.
