Abstract
Static property in a photographic material is effectively prevented by incorporating a specific copolymer formed from, as the copolymerizable components, a betaine-containing polymerizable monomer and a fluorine-containing polymerizable monomer, in the protective layer, backing layer, or an overcoat of the photographic material without exhibiting adverse influences on the photographic properties of the photographic material.
Claims15
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.sub.1 represents hydrogen, a halogen atom, an alkyl group, or a substituted alkyl group;
- R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, and R.sub.7 each represents hydrogen, an alkyl group, or a substituted alkyl group;
- R.sub.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.sub.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.sub.10 --, --O--CO--R.sub.10 --, ##STR20## wherein R.sub.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.sub.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.sub.2, R.sub.3 or R.sub.6 a heterocyclic ring,
- X represents --R.sub.12).sub.x Y--R.sub.13).sub.y W where Y and W represents --O--, --COO--, --OCO--, ##STR21## --NCO--, --S--, --SCO--, ##STR22## in which R.sub.11 has the same meaning as defined above, R.sub.12 and R.sub.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.
