| 摘要 |
The invention relates to a cosmetic agent containing at least one light stabiliser and at least one water-soluble or water-dispersible polymer which contains a) between 5 and 50 wt. % of at least one a,b-ethylenically unsaturated monomer of general formula (I) wherein R1 represents hydrogen or C1-C8 alkyl, and X1 represents O or NR2, R2 representing hydrogen, C1-C8 alkyl or C5-C8 cycloalkyl, b) between 25 and 90 wt. % of at least one N-vinylamide and/or N-vinyl lactam, c) between 0.5 and 30 wt. % of at least one compound having an a,b-ethylenically unsaturated double bond which can be radically polymerised and at least one cationogen and/or cationic group per molecule, d) between 0 and 30 wt. % of at least one a,b-ethylenically unsaturated monomer of general formula (II) wherein R3 represents hydrogen or C1-C8 alkyl, X2 represents O or NR5, R5 representing hydrogen, C1-C8 alkyl or C5-C8 cycloalkyl, and R4 represents hydrogen or a linear C1-C22 alkyl radical, in addition to the salts of said monomer. |
