Abstract:
A method for stabilizing chemical compounds containing at least one ethylenically unsaturated bond in order to prevent undesirable radical polymerization, whereby a nitroxyl radical and a chemical compound containing chemically bonded phosphorus are added to an unsaturated compound existing in the form of a pure substance or constituent in a mixture.
Abstract:
The invention relates to radiation-curable coating substances containing NIR photoinitiators, to novel formulations of NIR photoinitiators and to the use of said substances.
Abstract:
The invention relates to a composition for producing a thermal insulation coating, which comprises at least one radiation-absorbing compound and at least one IR reflector constituent. The invention also relates to a thermal insulation coating comprising the aforementioned oriented and cured composition, and to a method for the production thereof.
Abstract:
The invention relates to a method for the marking of hydrocarbons, by addition of at least one first marking agent( subsequently referred to as first marking agent), characterised in that, in addition, at least one further second marking agent is added to the hydrocarbon, which, under conditions for removal of the first marking agent, is not completely removable from the hydrocarbon. The invention further relates to hydrocarbons which are to be marked by said method, solutions for marking hydrocarbons, containing at least one first marking agent and at least one second marking agent as defined by the method according to the invention and optionally containing further additives.
Abstract:
Disazo dyes of formula (1) where one of the two symbols X?1 and X2¿ means hydroxy and the other amino, while D?1 and D2¿ means the residue of a disazo component from the aniline series. The invention also relates to sulphonamides as their intermediate producs and to the use of the new dyes for the dyeing of natural or synthetic substrates.
Abstract:
Disclosed is a mixture containing (A) at least one aromatic heterocycle of general formula (I), wherein W, X, and Y can independently represent hydrogen, NR 1 R 2 , O-R 3 , P-R 2
Abstract:
The invention relates to cosmetic or dermatological preparations for avoiding or decreasing skin damage as a result of formed peroxide or hydro-peroxide from endogenous or exogenous factors. Said preparations contain a) at least one active antioxidant as an O or C radical scavenger and b) at least one organic or inorganic skin tolerant compound, which reduces the peroxide or hydro-peroxide to the appropriate alcohol without creating subsequent active radical steps. Said compound is chosen in such a way that it reacts at body temperature substantially faster than the compounds in the skin containing sulphur.
Abstract:
The invention relates to a mixture, comprising (A) 10 to 90 wt. % of at least one C6 to C18 alkyl ester, or C5 to C8 cycloalkyl ester of 2-cyano-3,3-diphenylacrylic acid and (B) 90 to 10 wt. % of at least one further compound, with at least one UV absorption maximum in the range 280 to 450 nm and structurally different from compound (A). Said mixture is suitable for the protection of human skin from damaging UV radiation and for the protection of coloured textile materials from colour fading.
Abstract:
Liquid-crystalline compounds have the general formula (I): X(-Y-A-Y-M-Y-B)n, in which X is an aromatic or aliphatic ring system; n is an integer from 2 to 6; the Y symbols represent independently from each other a direct bond, -COO-, -OCO-, -O-, -CONH- or -CON(R)-, in which R = C1 to C4 alkyl; A is a spacer; M is a mesogene group; and B is a lateral chain. These compounds are particularly suitable in displays or for producing light-reflecting layers.
Abstract:
The present invention relates to a method of marking liquids using at least two markers, wherein said markers absorb in the 600-1200 nm region of the spectrum and reemit fluorescent light and the absorption range of at least one marker overlaps with the absorption range of at least one other marker.The present invention further relates to a method for detecting markers in liquids marked by the method of the invention, which comprises using light sources which emit radiation in the absorption ranges of said markers and detecting the fluorescent light reemitted by said markers, at least one of said light sources emitting radiation in the overlapping absorption range of at least one marker with that of at least one other marker and the number of light sources being less than or equal to the number of markers.The present invention further relates to liquids marked by the method of the invention.
