|20130143051||HYDROXYPHENYL TRIAZINES WITH AN AROMATIC CARBOCYCLIC FUSED RING SYSTEM - The instant invention relates to novel hydroxyphenyl triazine UV-absorbers with an aromatic carbocyclic fused ring system having a long wavelength shifted absorption spectrum with significant absorbance up to 420 nm. Further aspects of the invention are a process for their preparation, a UV stabilized composition containing the new UV-absorbers, a process for the stabilization of organic materials and the use of the new compounds as UV-light stabilizers for organic materials.||06-06-2013|
|20110086816||Antimicrobial Compounds - The invention relates to cationic siloxane derivatives for use especially as fungicides and/or antiadhesives. The cationic siloxane derivatives have the formula (I), wherein R1, R2, R3, R4, R||04-14-2011|
|20090194617||Method of producing low-dust granules from polymer additives - The invention relates to a technically advantageous method of producing low-dust granules of polymer additives or polymer additive mixtures. The granule-forming polymer additives are mixed together, the mixture is converted into a workable mass and pressed through an orifice. The pre-shaped strand-like extruded mass is cooled and, while still in a workable state, formed into granules by rolling, impressing, cooling and comminuting.||08-06-2009|
|20090191420||Coating Composition for Marking Substrates - Composition, which comprises a latent activator and a colour former, a process for the preparation of these compositions, substrates coated with these compositions and a process for their preparation, a process for preparing marked substrates using these compositions and marked substrates obtainable by the latter process.||07-30-2009|
|20090057613||FLUORESCENT QUINACRIDONES - The present invention relates to compounds of the Formula (I), a process for their preparation and their use for the preparation of inks, colorants, pigmented plastics, coatings, non-impact-printing material, color filters, cosmetics, polymeric ink particles, toners, as fluorescent tracers, in color changing media, in solid dye lasers and electroluminescent devices. A luminescent device comprising a composition according to the present invention is high in the efficiency of electrical energy utilisation and high in luminance.||03-05-2009|
|20090018354||PREPARATION OF ALPHA-HYDROXY AND ALPHA-AMINO KETONES - A process for the preparation of an 1,1-disubstituted oxirane is disclosed, wherein an organic sulphide is reacted in a polar solvent with an educt containing a leaving group attached to a primary or secondary carbon atom, and/or the sulfonium salt formed in this way is reacted with a ketone in presence of a base and a polar solvent. Oxiranes of the type obtained may be further converted into the corresponding α-hydroxyketone or α-aminoketone, either in one step by subjecting to aerobic oxidation in the presence of a transition metal catalyst, or in two steps by hydrolyzation in the presence of an aqueous acid to the corresponding dialcohol and subsequent selective oxidation. Further described are some novel epoxide intermediates. The α-hydroxyketones and α-aminoketones thus obtainable are useful inter alga as photoinitiators.||01-15-2009|
|20080199726||Electroluminescent Device - Disclosed are electroluminescent devices that comprise organic layers that contain triazine, or pyrimidine compounds. The compounds are suitable components of, for example, blueemitting, durable, organo-electroluminescent layers. The electroluminescent devices may be employed for full color display panels in, for example, mobile phones, televisions and personal computer screens.||08-21-2008|
