Claims
- 1. A photographic element comprising a support, having on a first side thereof at least one silver halide emulsion layer, and having on a second side an antistatic layer, and overlying the antistatic layer a protective overcoat farthest from said support; said protective overcoat comprising a continuous polyolefin coating.
- 2. The photographic element of claim 1 wherein said support is selected from the group consisting of cellulose esters, cellulose triacetate, cellulose diacetate, cellulose acetate propionate, polyethylene terephthalate, polyethylene naphthalate, poly-1,4-cyclohexanedimethylene terephthalate, polybutylene terephthalate, polyimides, polyamides, polycarbonates, polystyrene, polyethylene, polypropylene, polysulfones, polyacrylates, and polyether imides.
- 3. The photographic element of claim 1 wherein the antistatic layer comprises an antistatic agent selected from the group consisting of electrically conductive metal-containing particles, donor-doped metal oxides, metal oxides containing oxygen deficiencies, conductive nitrides, conductive carbides, conductive borides, semiconductive metal salts, fibrous conductive powders, and conductive polymers.
- 4. The photographic element of claim 1 further comprising a magnetic recording layer superposed on the first or second side of the support.
- 5. The photographic element of claim 1 further comprising spacer layers, filter layers, interlayers, antihalation layers, pH lowering layers, timing layers, opaque reflecting layers, or opaque light-absorbing layers superposed on the first or second side of the support.
- 6. The photographic element of claim 1 wherein the polyolefin coating comprises an aqueous dispersion of polyethylene, polypropylene, polybutylene, copolymers of polyethylene, copolymers of polypropylene, or copolymers of polybutylene.
- 7. The photographic element of claim 6 wherein the aqueous dispersions comprise polyolefin particles smaller than 1 micron, preferably less than 0.5 microns.
- 8. The photographic element of claim 1 wherein the polyolefin binder has a melting point below 150.degree. C.
- 9. The photographic element of claim 1 wherein said overcoat further comprises fillers, matte particles, surfactants, coating aids, coalescing aids, dyes, UV stabilizers, or thermal stabilizers.
- 10. The photographic element of claim 1 wherein said overcoat has dried thickness of greater than 100 mg/m.sup.2.
