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.

摘要： A laser-ablatable element for direct laser engraving has a laser-ablatable, relief-forming layer that has a relief-image forming surface and a bottom surface. This relief-forming layer includes a laser-ablatable polymeric binder and an infrared radiation absorbing compound that is present at a concentration profile such that its concentration is greater near the bottom surface than the image-forming surface. This arrangement of the infrared radiation absorbing compound provides improved ablation efficiency, particularly when laser exposure is carried out adiabatically.

摘要： A method is used to make a laser-ablatable element for direct laser engraving that has a laser-ablatable, relief-forming layer that has a relief-image forming surface and a bottom surface. The relief-forming layer can be prepared by applying multiple formulations. Each formulation comprises a coating solvent, a laser-ablatable polymeric binder, and an infrared radiation absorbing compound. The infrared radiation absorbing compound concentration in the resulting sub-layers is different in each adjacent pair of sub-layers so that the concentration is always greater in each pair sub-layer that is closer to the substrate, and the concentration is progressively greater in the sub-layers as they are closer to the substrate after the coating solvent is removed, wherein the multiple sub-layers provide a relief-forming layer so that the sub-layer farthest from the substrate provides a relief-image forming surface.
