Date Sep. 20, 1990.A process for the manufacture of reflectors, in particular reflectors for automotive vehicle headlamps, wherein a metallic film is applied to a metallization primer cured by UV or electron radiation. The radiation-curable metallization primer comprises A) 10 to 50% by weight of an acrylate copolymer containing ethylenically unsaturated side chains and having a number average molecular weight of 6,000 to 14,000, B) 4 to 50% by weight of a mixture of b1) 2 to 20% by weight of a monomer or oligomer containing three acryloyl groups, b2) 2 to 20% by weight of a polyethylenically unsaturated aliphatic oligomer of the formula (I) <IMAGE> (I) b3) 5 to 20% by weight of a difunctional acrylic carbonate monomer, C) 1 to 8% by weight of a photoinitiator, D) 0 to 5% by weight of customary auxiliaries and additives, and E) 0 to 60% by weight of one or more solvents inert toward components A-D the components A to E in each case totalling 100% by weight.</p> |
