Patent application numberDescriptionPublished
20090162307Photolatent Systems - The instant invention relates to new photolatent compounds of the formula I wherein R06-25-2009
20090302284Reversibly Thermochromic Compositions - The present invention pertains to a reversibly thermochromic system comprising a substituted or an unsubstituted 6,11-dihydroxy-naphthacene-5,12-dione and a base and to a reversibly thermochromic composition comprising the reversibly thermochromic system and a carrier material and to novel substituted 6,11-dihydroxy-naphthacene-5,12-diones.12-10-2009
20100234494Reversibly thermochromic compositions - A reversible thermochromic system comprising a) a compound of the formula (I) or a tautomer thereof (I) wherein R09-16-2010
20100234522Reversible Thermochromic Compositions - The present invention pertains to a reversible thermochromic system comprising a β-phenylvinylketone or a ω-phenyl polyacetylenyl ketone with at least one acidic hydrogen and a base and to a reversible thermochromic composition comprising the reversible thermochromic system and a carrier material and to novel substituted β-phenylvinylketones or ω-phenyl polyacetylenyl ketones with at least one acidic hydrogen.09-16-2010
20100249401Process for the preparation of sterically hindered nitroxyl ethers - The present invention relates to a novel process for the preparation of a sterically hindered nitroxyl ether from the corresponding sterically hindered nitroxyl radical by reacting it with a carbonyl compound and a hydroperoxide. The compounds prepared by this process are effective stabilizers for polymers against harmful effects of light, oxygen and/or heat, as flame-retardants for polymers and as polymerization regulators.09-30-2010
20110017611OXYGEN-SCAVENGING MIXTURES - An oxygen-scavenging mixture comprising the components (I) a nano-sized oxidizable metal component wherein the average particle size of the metal is 1 to 1000 nm and wherein the metal is unsupported or supported by a carrier material, (II) an electrolyte component, and (III) a non-electrolytic, acidifying component.01-27-2011
20110160453Process for the preparation of sterically hindered nitroxyl ethers - The present invention relates to a novel process for the preparation of specific sterically hindered nitroxyl ethers from their corresponding sterically hindered nitroxyl radicals by reacting it with an aldehyde and a hydroperoxide. This nitroxyl ether formation may be carried out from different starting nitroxyl radicals, which are subsequently further reacted to the desired compounds. The compounds prepared by this process are effective as stabilizers for polymers against harmful effects of light, oxygen and/or heat and as flame-retardants for polymers.06-30-2011
20110180767Reversibly thermochromic compositions - A reversible thermochromic system comprising a) a compound of the formula (IA) or a tautomer thereof or a compound of the formula (IB) or a tautomer thereof (IA) (IB) wherein R07-28-2011
