Abstract: A pharmaceutical tablet consists of a substrate containing a medicament and may be covered with a coating, said coating including a pigment comprising a natural water insoluble edible powder dyed with an edible natural dye. The pigment for coloring the tablet, or other pharmaceutical products, as well as food and cosmetics, is made by suspending a natural water insoluble edible powdered substrate in an aqueous vehicle and dyeing the suspended powdered substrate with an edible natural dye. The liquid is removed to obtain the dry pigment powder of the invention which then can be suspended in a suspending medium and used for coating products to be colored such as food, drug and cosmetic products.

Abstract: Synthetic fibers such as polyethylene terephthalate and nylon are treated with certain polydiorganosiloxanes to provide improved properties such as "hand" and water repellency. When the polydiorganosiloxanes contain approximately two silicon-bonded amino radicals of the formula --R'(NHCH.sub.2 CH.sub.2).sub.a NHR", such as --CH.sub.2 CH.sub.2 CH.sub.2 NHCH.sub.2 CH.sub.2 NH.sub.2, they provide a crosslinked siloxane on the surface of the treated fiber, when heated, which does not diminish the fire-retardancy rating of the fibers.

Abstract: The discharge printing past contains the sodium or calcium salt of a sulfonated derivative of an N-alkylated benzylphenyl ammonium halide which acts as a sequestering and solubilizing agent for the indigo blue. It is used in conjunction with a reducing agent (or an oxidizing agent) and a bleaching agent or process resistant dye, depending on whether the print is to be white or colored. After developing in the presence of a second removing agent and a strong dispersing agent, the textile stock is washed, dried, subjected to conventional finishing treatments and again dried.

Abstract: Azo dyestuffs which contain, as the coupling component an indole of the formula ##STR1## wherein R denotes an optionally substituted alkyl radical, an optionally substituted aryl radical or an optionally substituted aralkyl radical, and the benzene ring A can be further substituted,frequently exhibit an undesired irreversible change in the color shade in acid solutions, which surprisingly can be prevented by adding nitrogen-containing complex-forming substances.

The sulphurylamide may also be applied in the presence of a dispersant, a protective colloid and/or water. The composition of matter for performing this process is also provided.

Abstract: The color printing of textile webs or structures such as carpets and tiles which are tufted or non-woven wherein the color is sublimatic dyestuff carried by an air permeable printing foil and this is placed over the textile structure with the dyestuff facing the textile structure. Heat is applied to vaporize the dyestuff and a pressure differential across the textile structure causes an air flow through the sheet structure and printing foil to affect penetration of the dye vapor into the structure. The dyestuff deposits on the textile fibres and filaments in the pattern it appeared on the printing foil. The said pressure differential is preferably produced by creating a vacuum at the side of the sheet structure opposite the printing foil.
