    摘要: Photographic elements and assemblages are described employing positive-working redox dye-releasers, wherein the element contains an oxidant which is located between the support and the photosensitive portion thereof. The oxidant has an electrode potential of from about -200 mV up to about 1200 mV versus a saturated calomel electrode at a pH of about 5 to about 6. After processing, the oxidant reacts with the electron transfer agent to prevent it from reacting with the dye releaser which would otherwise cause further dye release. The reduced form of the oxidant is then substantially incapable of reducing the positive-working redox dye-releaser. D.sub.min stability is thereby improved.

    摘要: A photographic imaging element is disclosed comprising a support having on a front side thereof a silver halide imaging layer and an outermost protective overcoat layer comprising a film-forming binder, and on the backside thereof an outermost protective backcoat layer comprising a film-forming binder; the protective overcoat and backcoat layers each comprising a lubricant present in an amount of at least 5 mg/m2 and permanent matting agent having a Tg of at least 40° C. and an average particle size of from about 0.5 to about 3 micrometers in an amount of at least 1 mg/m2; and at least one of the protective overcoat layer or the protective backcoat layer further comprising crosslinked elastomeric polymer matte particles, wherein the crosslinked elastomeric polymer matte particles have a Tg of 20° C. or less, an average particle size of at least 90% of or greater than that of the permanent matting agent particles having a Tg of at least 40° C. in the protective layer in which the crosslinked elastomeric matte is included, and are present in the protective overcoat layer or protective backcoat layer in an amount which is (i) at least 1 mg/m2 and (ii) less than the total level of permanent matting agent particles having a Tg of at least 40° C. in the protective overcoat and backcoat layers combined. Imaging elements comprising highly lubricated protective outermost layers in accordance with the invention advantageously provide increased scratch and wear resistance, while the presence of relatively low Tg crosslinked elastomeric matte particles in combination with higher Tg permanent matte particles has been found to increase the coefficient of friction of the layer in which they are included to provide good manufacturability of the imaging element while also maintaining wear and other desired film performance properties.

    摘要: A motion picture intermediate film has on one side of a support material, in order, an antihalation undercoat and at least one silver halide emulsion layer; and on the opposite side of the support a transparent, process surviving antistatic backing layer. The transparent, antistatic backing layer retains its antistatic properties after photographic film processing so that the motion picture intermediate film is protected from the generation of static charge during high speed printing of, for example, motion picture print films. The antistatic backing layer of the invention has a resistivity of less than about 1×1011 &OHgr;/□ after film processing. In a most preferred embodiment, the motion picture intermediate film of the invention is used to print images onto a motion picture print film that has a transparent antistatic backing layer. In accordance with the invention, use of a motion picture intermediate film as described above in making multiple prints onto motion picture print film results in surprisingly decreased levels of dirt and other image defects in the projected motion picture print film images, especially where such intermediate film is used to print onto print films having a process surviving antistatic backing layer.

    摘要: Photographic assemblages are described employing positive-working redox dye-releasers and a cover sheet containing an oxidant having an electrode potential of from about -200 mV up to about 1000 mV versus a saturated calomel electrode at a pH of about 5 to about 6. The oxidant is capable of oxidizing electron transfer agent in the system. The reduced form of the oxidant is incapable of reducing the positive-working redox dye-releaser. After processing, the oxidant reacts with the electron transfer agent to prevent it from reacting with the dye releaser which would otherwise cause further dye release. D.sub.min stability is thereby improved.
