Abstract
This invention relates to radiation hardenable primers based on prepolymers containing (meth) acryloyl groups and conventional auxiliary agents. The primers are characterized in that they contain organic and/or inorganic fibres having a fibre length distribution curve reaching its maximum in the region of from 50 to 600 .mu.m. These primers are suitable for coating articles which have absorbent surfaces, in particular for the continuous coating of wood-concrete articles such as wood-concrete boards.
