| abstract |
The invention relates to curable compositions Z, which contain a binding agent BM that carries at least one ethylenically unsaturated group, in addition to particles P that have at least one ethylenically unsaturated group on their surface and comprise groups of general formula (I), -SiR22-(CR32)n-A-D-C. In said formula, R2 represents -(CR32)n-A-D-C or a hydrocarbon group comprising between 1 and 12 carbon atoms, the carbon chain of said hydrocarbon group being interrupted by non-adjacent oxygen, sulphur or NR4 groups, R3 represents hydrogen or a hydrocarbon group comprising between 1 and 12 carbon atoms, the carbon chain of said hydrocarbon group being interrupted by non-adjacent oxygen, sulphur or NR4 groups, R4 represents hydrogen or a hydrocarbon group comprising between 1 and 12 carbon atoms, A represents oxygen, sulphur, =NR4 or =N-(D?C), D represents a carbonyl group, or an alkene, cycloalkene or arylene group comprising between 1 and 12 carbon atoms, the carbon chain being interrupted by non-adjacent oxygen, sulphur, or NR4 groups, C represents a terminal unsaturated group and n represents values that are greater than or equal to 1. |
