摘要:
The present invention is a photographic element containing a support, at least one light sensitive emulsion layer superposed on the first side of the support, and an outermost lubricant layer superposed on the support. The outermost layer includes more than 80 percent by weight of a composite wax particle. The composite wax particle includes a wax phase and a non-crosslinked polymer phase. The wax phase is greater than 80 percent by weight of a wax which has a melting point of greater than 30° C. In one embodiment the lubricant layer contains a fluoro containing compound. It is envisioned that the lubricant layer overlies a transparent magnetic layer. The total coating weight of the composite wax particle in the lubricant layer is in the range of from 1 to 300 mg/m2. Preferably, the fluoro compound contains at least one type of an ionic group or a nonionic group.

摘要:
The present invention is a method of producing an imaging support which includes providing a support, simultaneously coating on a side of the support; a transparent magnetic recording layer comprising magnetic particles, a polymeric binder and an organic solvent, and a lubricating overcoat layer farthest from the support, the lubricating overcoat layer comprising wax particles having a size from 0.01 .mu.m to 0.5 .mu.m, and an organic solvent; and drying the magnetic recording layer and the lubricating overcoat layer.
摘要:
A method for manufacturing an optical compensator (5) on a transitional substrate (8) comprises applying a first orientation layer (20) to the transitional substrate. The first orientation layer (20) is then aligned and a first anisotropic liquid crystal material (30) is applied on the first orientation layer. In one embodiment, a retardation layer (10) is located between the transitional substrate (8) and the first orientation layer (20).
摘要:
A concentrated fine solid particle dispersion useful for forming a substantially photographically transparent magnetic recording layer is disclosed, comprising an organic solvent medium containing a dispersing agent and dispersed magnetic particles, wherein the magnetic particles are present at a concentration of at least 25% by weight and the organic solvent medium is comprised primarily of organic solvent selected from dimethyl succinate, dimethyl glutarate and dimethyl adipate. This invention provides a stable concentrated dispersion of magnetic particles useful for preparing substantially photographically transparent magnetic recording layers. A film-forming binder solution can be added to dilute the concentrated dispersion, which then can be applied to a support to form a transparent magnetic layer for a magnetic recording element. This invention also provides a photographic element which contains a magnetic recording layer which has excellent magnetic characteristics and which is substantially photographically transparent by virtue of its low granularity and optical density.
