The polymerisable composition contains a) from 30 to 90 per cent by weight of a silane containing at least one terminal epoxide group, b) from 10 to 70 per cent by weight of an aliphatic polyepoxide, where the aliphatic epoxide gives on homopolymerisation a polymer having a glass transition temperature of below -25 DEG C and has a molecular weight of at least 100 per epoxide group, and c) a compound which absorbs ultra-violet radiation, in an amount sufficient to absorb at least 90% of all radiation between 290 and 400 nm by a moist film thickness of 20 mu m. The composition can be used for the production of an abrasion-resistant film which absorbs ultra-violet radiation. |
