A decorated synthetic resin sheet is formed by a continuously cast sheet of polymerized synthetic resin syrup integrally joined on at least one side with one side of an unwrinkled uniformly thick preformed film of polymerized synthetic resin that is compatible with the cast syrup. The film and sheet are integrally joined together to form a homogeneous product.

Decorated synthetic resin sheet

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.
