Abstract: A stabilizer mixture for one or more compounds of the general formula (1) and (1A) but preferably (1), wherein the groups R independently stand for an alkyl-, cycloalkyl-, aralkyl- or aryl-rest whereas the aromatic ring system may be optionally substituted by one or more groups R? which may be identical or different and which groups R? can be an aryl-, a saturated or unsaturated alkyl-, aralkyl- or cycloalkyl-group as well as halogen, an amino-, aminoalkyl-, aminocycloalkyl-, cyano-, thiocyano- or nitrogroup. and a UV-absorber, hindered amine stabilizer, sterically hindered phenol, organophosphite, organophosphonite, organophosphine, or mixtures thereof. The present invention is useful in the protection of various polymeric substrates against the damaging influence of light exposure by the long term storage of polymers. This effect can be observed especially in so-called engineering plastics (such as, for example, PC, PET, PBT, ABS, TPU).

Abstract: A method for making high softening point linear and cyclic alkylsilicone waxes includes reacting a C30+ alpha olefin wax with a silicone hydride polymer in the presence of a catalyst. The high softening point linear and cyclic alkylsilicone waxes have softening points approximating those of natural waxes and, in consequence, can be used in applications which traditionally employ natural waxes.
Abstract: Disperse dyes of the general formula (I) where D is a diazo component derived from a substituted or unsubstituted aromatic amine, K is an aromatic radical of the formula and the substituents are each as defined in the first claim. Further described are the preparation and the use of the dyes according to the invention.
Abstract: The present invention relates to the use of compounds of formula (I) wherein all substituents are as defined in the claims as optical brighteners as well as to new mixtures of optical brighteners.
Abstract: Fibre-reactive trisazo compounds of the formula (I) bearing halogenated pyrimidine reactive moieties and where the substituents are each as defined in the claims, and also the associated synthesis, the use of the compounds for dyeing or printing hydroxyl-containing or nitrogenous organic substrates, the use of the compounds as a component in an inkjet printing ink and also the dyed or printed substrates.
Abstract: The invention relates to reaction products of glycols, diglycols, higher glycols or glycerol with ?-hydroxycarboxylic acids in a molar ratio of 1:2 or higher, especially conforming to the general formula (V) where R is hydrogen or a C1-3 alkyl group, preferably methyl, nx is from 1 to 5, preferably from 1 to 3, n is 1 or 2 and when n=1 the radical R? is C1-4 alkylene, preferably ethylene, x is defined as x? and y is not less than 1, preferably from 1 to 5, especially 1 or 2, and when n=2 the radical R? is a glycerol radical, x is defined as x? and y is =1. The invention further relates to the use of the (poly)hydroxycarboxylic acid (poly)glycol esters or (poly)hydroxycarboxylic acid glyceryl esters as acid donors and for controlling the pH in textile treatment processes.

Abstract: A color matching system including a database of information describing colorants organized into groups of colorants. A computing device identifies at least one recipe of colorants that can reproduce a desired color by selecting at least one group of colorants, identifying possible recipes using the colorants in the group and selecting a best recipe from the possible recipes based on a recipe cost and a calculated metamerism of the recipe.

Abstract: The instant invention relates to stabilizer compositions for thermoplastic polymers comprising a) at least one organophosphine, b) at least one 2-phenylbenzofuranone, and c) at least one sterically hindered piperidine based stabilizer (HAS), wherein the weight ratio of component a) to component b) to component c) is from 1:0.05:0.5 to 1:3:5. The instant compositions need an overall lower concentration as compared with the conventional phenol-containing formulations. In polyolefin articles, particularly in polyolefin-fibers, discoloration during processing and service life by both the formation of quinoid products and by action of NOx gases (gasfading) is avoided.
