Photographic materials

Claim 1

A silver halide photographic material comprising a support and at least one layer of the photographic material containing a copolymer including, as copolymerizable components, a betaine-containing polymerizable monomer represented by formula (I) or (II) and a fluorine-containing polymerizable monomer represented by formula (III) ##STR19## wherein R 1 represents hydrogen, a halogen atom, an alkyl group, or a substituted alkyl group; R 2 , R 3 , R 4 , R 5 , R 6 , and R 7 each represents hydrogen, an alkyl group, or a substituted alkyl group; R 8 represents a hydroxy group, a nitro group, a halogen atom, a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms or a substituted or unsubstituted acyl group having from 1 to 6 carbon atoms, or when m>1 said R 8 s may combine with each other to form a ring; A represents a chemical bond, a substituted or unsubstituted alkylene group having from 1 to 8 carbon atoms, a substituted or unsubstituted aralkylene group having from 6 to 11 carbon atoms, --COO--R 10 --, --O--CO--R 10 --, ##STR20## wherein R 10 represents a chemical bond, an alkylene group having from 1 to 8 carbon atoms, an aralkylene group having from 6 to 11 carbon atoms or an arylene group; and R 11 represents a hydrogen atom, an alkyl group having from 1 to 8 carbon atoms which may be substituted, or an atomic group necessary for forming together with R 2 , R 3 or R 6 a heterocyclic ring, X represents --R 12 ) x Y--R 13 ) y W where Y and W represents --O--, --COO--, --OCO--, ##STR21## --NCO--, --S--, --SCO--, ##STR22## in which R 11 has the same meaning as defined above, R 12 and R 13 represent a chemical bond, an alkylene group having from 1 to 8 carbon atoms; an aralkylene group having from 6 to 11 carbon atoms, or an arylene group; and x and y are 0 or 1; and Z represents a 5-membered or 6-membered ring including a quaternary nitrogen atom which may contain an oxygen atom or a non-quaternary nitrogen atom.
