    摘要： The present invention is an imaging element which includes a support, at least one imaging layer superposed on the support and a protective topcoat superposed farthest from the support. The topcoat includes a binder and lubricant droplets. The lubricant droplets are composed of a lubricant and a water soluble polymer containing heterocyclic aromatic nitrogen groups wherein the droplets are surrounded by a particulate stabilizer. The present invention is also directed to the lubricant droplets.

    摘要： A photographic element is disclosed comprising a film support, at least one light-sensitive layer, a highly loaded layer which contains more than 30 volume percent of non-film forming particulate material, and upper and lower aqueous coated adjacent layers which are next to the highly loaded layer, the upper adjacent layer being further from the support and the lower adjacent layer being closer to the support relative to the highly loaded layer, each adjacent layer having a film forming binder content of greater than 70 volume percent, and the lower adjacent layer being at least 1.0 micron thick. In accordance with a preferred embodiment of the invention, an imaging element having excellent adhesion characteristics is obtained in combination with excellent magnetic recording characteristics and photographic transparency where the non-film forming particulate material in the highly loaded layer comprises conductive particles, the layer adjacent to the highly loaded layer which is closer to the support comprises a hydrophilic curl control layer, and the layer adjacent to the highly loaded layer which is further from the support or a layer coated thereover comprises an aqueous coated transparent magnetic recording layer, by virtue of the physical flatness, low granularity, and optical density of the element. Also disclosed is a process for simultaneously applying a plurality of coating compositions comprising an aqueous magnetic recording layer coating composition, an antistatic layer aqueous coating composition, and a curl control layer aqueous coating composition, along with other optional conventional gelatin containing aqueous coated layers, onto a support. The placing of the highly filled antistatic layer between two aqueous coated adjacent layers, which in a preferred embodiment of the invention comprise a magnetic recording layer and a curl control layer or two curl control layers, results in excellent adhesion of the coated layers to the support compared to where the antistatic layer is closest to the support. The mechanical properties of a photographic element containing such a highly filled layer is substantially strengthened when the highly filled layer is sandwiched between the two other aqueous coated layers.

    摘要： The present invention is an imaging element which includes a support, an image forming layer superposed on the support; and an antistatic layer superposed on the support. The antistatic layer includes electrically conductive particles at a 10-60 volume percent and microgel particles. The microgel particles are composed of 25 to about 80 weight percent of an oleophilic monomer, 5 to about 45 weight percent of a hydrophilic monomer, and 0 to 20 weight percent of a crosslinking monomer having at least two addition polymerizable groups. In an alternative embodiment the antistatic layer also includes a binder.
