Provided is a treated platy substrate, a method of making it, and methods of using it. The substrate can be synthetic mica, optionally comprising metal-oxide layers. The treated platy substrate is useful in cosmetic compositions.

Treated platy substrates

Blending an electrically active, anodically coloring, electrochromic polymer with a non-electrochromic, non-electrically conductive binder polymer greatly enhances the performance of the anodically coloring, electrochromic polymer in an electrochromic device over time. In addition to improved physical characteristics of the blend, e.g., film build, durability etc, the coloristic properties, including color space and color strength, of the device comprising the blend are more durable than when using the neat polymer, and in certain instances, the color space and color intensity provided by the blend is superior to that available from the neat polymer.

Electrochromic devices and polymer compositions

Electrically active, cathodically coloring electrochromic polymers are blended with a non-electrochromic, non-electrically conductive binder polymer to provide an electrochomic composition with greatly enhanced performance in an electrochromic device over time. It is also found that blending an electrochromic polymer with a non-coloring electroactive material allows for greater design in preparing electrochromic devices as it enables the use of a higher amount of typically low coloring anodic materials due to increased need for charge balancing.

Devices containing compositions comprising cathodically coloring electrochromic polymers and binder polymers

Disclosed are compositions, which are stabilized against degradation and yellowing during exposure to ultraviolet light by the presence of certain nitroxyl, hydroxyl amine and hydroxyl amine salt additives, a method of stabilizing the compositions by the addition of said additives, to the use of such compositions as media in electroactive devices such as electrochromic and electrophoteric devices, and the electroactive devices comprised of these media.

Stabilized electrochromic media

An ink jet recording media system is described which comprises at least one coating layer that comprises a zwitterionic copolymer or cooligomer, which copolymer or cooligomer comprises monomer units derived from at least one monomer selected from the group consisting of the zwitterionic monomers and at least one monomer selected from the group consisting of the hydroxy functional monomers and etherified hydroxy functional monomers. The media system exhibits fast dry times, excellent image quality, low levels of glycol smear, low color coalescence and excellent light fastness.

Ink jet recording medium

An ink jet recording media system is described which comprises at least one coating layer that comprises a zwitterionic polymer or oligomer. The media system exhibits excellent light fastness as well as good dry time and good image-forming properties.
