<p>The invention relates to a process for producing injection mouldings from plastic, in particular polyurethane, the surface of which is to have on at least parts of its extent a colouring which differs from the colour of the actual injection moulding. The colouring of these surface regions is produced by applying, onto the inner surface of the injection mould, in the regions or at the points which correspond to the regions or points of the injection moulding which are to be coloured, a coating of a polyurethane colour the composition of which is chosen such that it forms a firm bond with the material forming the actual injection moulding, so that, as a result, the injection moulding and surface colour are integral.</p> |
