Abstract
Synthetic resin sheet material having a film, possibly bearing printing on at least one of its surfaces, with the film forming an integral part of the material is made by feeding the film together with a polymerizable syrup into a continuous plastic casting machine, the film being compatible with the syrup so that during passage through the machine with the syrup, the film softens and at least slightly dissolves in the syrup during polymerizing of the syrup and consequent solidifying of all of the components together.
