| 20090217465 | Process for Hair Dyeing Comprising Application of Composite Pigment - Disclosed is a process for dyeing of keratin-containing fibers comprising treating the fibers with at least one functionalized particle comprising on the surface an organic chromophore which is bound via a bridge member, wherein the particles are based on SiO | 09-03-2009 |
| 20090255063 | Polymeric hair dyes - Disclosed are polymeric dyes of formula (1a); (1b); or (1c); wherein A and B, independently from each other represent a polymer backbone; X | 10-15-2009 |
| 20100011518 | Tricationic dyes - Disclosed are compounds of formula | 01-21-2010 |
| 20100162494 | FUNCTIONALIZED NANOPARTICLES - Functionalized nanoparticles, which are obtainable by combining in a first step a functionalized dyestuff, a silicon-based spacer and a catalyst, and in a second step reacting the product obtained in the first step with a co-reactive organic silicon, aluminum, zirconium or titanium compound. Optionally, the thus obtained functionalized nanoparticles can be combined or encapsulated with a polymer. The functionalized nanoparticles are useful as colorants and fluorescents in plastics, paints, inks, electronic materials, cosmetic articles, and the like. | 07-01-2010 |
| 20100192312 | POLYMERIC DYES - A highly crosslinked polysiloxane dye comprising at least 10 Si atoms, including at least one moiety of the formula (I) whose open Si-bonds each are linked to an oxygen atom and open O-bond is linked to a silicon atom in the rest of the polysiloxane, and wherein T is a direct bond or an organic spacer group such as C | 08-05-2010 |
| 20110061179 | BLUE POLYMERIC HAIR DYES - Disclosed are cationic polymeric dye with a hue value of h=210° to 330° comprising: a) a polymer backbone, b) a residue of an organic dye, and c) optionally colorless organic groups, wherein (b) and (c) are covalently bound to the polymer backbone (a), and wherein the cationic charges can independently be part of the dye or the colorless organic groups. The dyes are distinguished by their depth of shade and their good fastness properties to washing, such as, for example, fastness to light, shampooing and rubbing. | 03-17-2011 |
