Suitable stabilizers for organic material are a mixture comprising  

Stabilizer mixture

The present invention relates to the use of certain benzotriazole derivatives of the general formula (I) 

High molecular weight nonpolar benzotriazoles

The invention relates to mixtures, comprising   

Process for the preparation of modified ZnO particles in which a zinc salt and a base are mixed in a polar solvent and, if appropriate after the precipitation of a precipitation product, the polar solvent is removed and a residue is obtained, where the residue is taken up in a nonpolar solvent, surface-active substances are added, optionally further effect substances are added and then the modified ZnO particles are separated off from further by-products. Materials such as plastics, coatings or paints comprising modified ZnO particles. Methods for the incorporation of modified ZnO particles into materials, where the modified ZnO particles are incorporated into the materials in the form of dispersions or suspensions. Use of modified ZnO particles for protecting material against the effect of light, heat, oxygen or free radicals, as catalysts, for semiconductive films or cosmetic applications.

Modified zinc oxide particles

A mixture comprising Use of such a mixture for stabilizing inanimate organic materials against the effect of light, oxygen and/or heat. Inanimate organic materials comprising at least one such mixture, and also articles produced from such inanimate organic materials. Methods of stabilizing inanimate organic materials against the effect of light, oxygen and/or heat by adding to said inanimate organic materials at least one such mixture in an effective amount.

Liquid stabilizer mixture

The present invention relates to the use of sterically hindered amines comprising one or more groups of the general formula (I) to stabilize inanimate organic material, more particularly plastics or coating materials, where Rand Reach independently, alike or different, are H, C-Calkyl, C-Ccycloalkyl, aryl, hetaryl or a heterocycle, R, R, R, and Reach independently, alike or different, are C-Calkyl, or Rand Ror Rand Rtogether are a tetramethylene or pentamethylene group, and Ris aryl or hetaryl. The invention further relates to methods of stabilizing inanimate organic material, especially plastics or coating materials. Additionally provided by the invention are selected sterically hindered amines comprising one or more groups of the general formula (I). Additionally provided by the invention are materials that comprise selected sterically hindered amines.

Stabilisers for inanimate organic materials

A description is given of the use of naphthalene-1,8-dicarboxylic monoimides of the formula (I), in which Ris hydrogen, alkyl, alkenyl, cycloalkyl, cycloalkenyl, heterocycloalkyl, aryl or heteroaryl and Ris a radical containing at least one &#x3c0; electron system containing a carbon atom and at least one further atom selected from carbon, oxygen, and nitrogen, with the proviso that the radical contains at least one atom other than carbon; to protect organic material from the damaging effects of light, of compositions which comprise at least one naphthalene-1,8-dicarboxylic monoimide of the formula (I) in an amount which provides protection from the damaging effects of light, and at least one organic material, and of new naphthalene-1,8-dicarboxylic monoimides (I).
