    摘要： The invention relates to a composition comprising i) 10-90 wt. % of an ethylenically unsaturated component (A), ii) 10-90 wt. % of a component (B) having urethane and/or urea groups, iii) 0-4 wt. % of an organic component (C) which is different from components (A) and (B), and iv) 0-9 wt. % of other ingredients (D) wherein the wt. % are calculated on the total weight of the composition, wherein the sum of the wt. % of component (A) and the wt. % of component (B) is 91-100 wt. %, component (A) consists of compounds having 1-8 ethylenically unsaturated bonds and a molar mass of 100-1400 g/mol, component (A) contains no amino groups, component (B) contains no primary and no secondary amino groups, component (B) consists of compounds having 2-40 functional groups selected from urethane and urea groups, having 1-40 groups selected from tertiary amino groups, salts thereof, quaternary ammonium groups, and mixtures thereof, component (B) contains not more tertiary amino groups than the sum of urethane and urea groups, and component (B) has a nitrogen content in the range of 1.0 to 12.0 wt. %, component (C) consists of organic compounds having a molar mass of less than 1000 g/mol.

    摘要： The present invention relates to curable compositions comprising at least one compound of the formula (1): wherein R is C1-C10 alkyl, and R1-R10 each are independently selected from the group consisting of hydrogen and C1-C10 alkyl, with the proviso that at least one of R1-R10 is alkyl, and wherein the substitution patterns formed by the residues R1-R5 and R6-R10 on each of the aromatic rings are different from each other, cured compositions obtained from such curable compositions, mixtures of compounds of the formula (I), the use of such compounds and mixtures of such compounds as a UV stabilizer in curable compositions, and a process for the manufacture of curable compositions comprising a UV stabilizer of the formula (1).
