The radiation-sensitive element consists of a carrier which carries a layer of a composition which can be photo-polymerised. The composition consists of (1) at least one compound which can be addition polymerised and is ethylenically unsaturated, (2) an initiator which can be activated in the ultraviolet to visible range of the spectrum, and (3) at least 20% by weight of a binding agent which can be polymerised and itself contains at least 5% by weight of acrylonitrile, there being at least 5% by weight of halogen, related to the total weight of the composition, in said composition, the halogen being bonded in a covalent manner to at least one component of the composition. The element is flame-retarding and can be used as a photoresist or as a soldering mask. |
