La présente invention a pour objet un article cosmétique substantiellement sec destiné à la coloration capillaire comprenant
-un substrat flexible poreux,
-un ou plusieurs colorants directs ou précurseurs de colorants directs sous forme de poudre et susceptibles de colorer la matière kératinique par transfert thermique, le substrat et les colorants directs ou précurseurs de colorants directs étant fixés de manière non covalente au substrat.
La présente invention a de plus pour objet un procédé de coloration de matières kératiniques mettant en oeuvre cet article cosmétique par transfert thermique à sec. Elle concerne également l'utilisation de cet article pour la coloration de matières kératiniques notamment humaines par transfert thermique à sec.

Disclosed are methods for coating or impregnating a surface with an antimicrobial agent that involve contacting the surface with a composition that includes an antimicrobial agent and a solvent, and curing the surface by applying heat. Also disclosed are methods for reducing the risk of development or progression of an infection in a subject in need of a medical device, that involve coating or impregnating a surface of the medical device with an antimicrobial agent and then curing the surface by applying heat, wherein the risk of development or progression of an infection is reduced.
An example article includes a substrate and a coating applied to the substrate. The coating includes a stabilizer and an organic phosphonic acid reactant. In an example article, the coating includes a water-soluble polymer and an organic phosphate or phosphonate reactant. An example coating configured to be applied to a basic gas filter substrate includes a water-soluble polymer and an organic phosphate or phosphonate reactant. An example technique includes applying a coating to a substrate and heating at least the coating to a temperature between about 100° C. and about 275° C. for about 1 minute to about 10 minutes. An example system includes a basic gas filter including a coating, and a sensor configured to sense an optical change in the coating.
Novel thermochromic and/or photochromic compositions are described. The thermochromic compositions include a thermoset resin, cholesterol, water, and dye, while photochromic compositions include a benzene and a binder, such as silica gel. When mixed, the ingredients of the thermochromic and photochromic compositions form chromic cells with an outer shell comprised of either the thermoset resin (in the case of thermochromic compositions) or potassium nitrate (in the case of photochromic compositions). When the chromic compositions are exposed to either a heat or light stimulus, the chromic cells compress to causing the dye within the cells to no longer be visible, thereby creating a color-changing effect.
