摘要： The antistatic property of a silver halide photographic material is effectively improved by incorporating a fluorine-containing water-soluble polymer having a styrene monomer containing a fluorine-containing group as the polymerization unit in at least one of the photographic layers of the photographic material. The incorporation of the polymer does not reduce the adhesion resistance or film strength of the photographic material. The photographic material can also maintain the improved antistatic property for a long period of time.

摘要： Compounds useful in making crosslinkable polymers having the formula (I): ##STR1## wherein R is hydrogen or methyl; R.sup.1 is cyano or ##STR2## wherein R.sup.2 is alkyl; Z is --X--R.sup.3 --X-- or ##STR3## wherein each --X-- is --O-- or --NR.sup.4 --, provided at least one --X-- is --NR.sup.4 -- wherein R.sup.4 is hydrogen or alkyl, R.sup.3 is divalent hydrocarbon and D.sub.1 and D.sub.2 together are the carbon atoms necessary to complete a 5 to 7 membered ring. These compounds can be homopolymerized or copolymerized with each other or with other polymerizable ethylenically unsaturated monomers to give crosslinkable polymers. Such polymers can be purified by conventional purification techniques such as dialysis, diafiltration, ultrafiltration without losing their capability of crosslinking. The resulting purified polymers are particularly useful in photographic materials as gelatin extenders, binders or polymeric color couplers.
