The invention relates to spray-dried, washfast dye compositions, preferably in the form of pigment powders, having a bleeding rate of &#x2264;0.5% and consisting of water-soluble functional dyes, preferably food dyes, which are firmly incorporated in a silica matrix. Apart from low bleeding of dye, these compositions are remarkable for their high stability to pH changes and/or ascorbic acid. The invention is also directed to the production of the dye compositions and the use thereof. The dye compositions are preferably employed in coloring foods, cosmetics, pharmaceutical products, but also in other uses.

Spray-dried dye compositions, process for the production and use thereof

An organic semiconductive material comprising at least one matrix material and at least one doping material, wherein the doping material is selected from an organic compound and wherein the matrix material is selected from an diamine compound, also an organic component and a mixture for producing a doped semiconductor layer.

Organic semiconducting materials and organic component

Organic semiconducting material comprising at least one matrix material and at least one doping material, wherein the doping material is selected from a [3]radialene compound, and wherein the matrix material is selected from a terphenyldiamine compound, as well as an organic component and a mixture for producing a doped semiconductor layer.
