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.
