Abstract: A nanocomposite optical plastic article has a plastic host material with a temperature sensitive optical vector (x) and a core shell nanoparticulate material dispersed into the plastic host material. The core shell nanoparticulate material is characterized by a core defined by a nanoparticulate material which has a temperature sensitive optical vector (x1) and a shell defined by a coating material layer coated onto the core. It is important to the invention that temperature sensitive vector (x1) is directionally opposed to the temperature sensitive optical vector (x) and nshell<nplastic host<ncore.

Abstract: 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.
