Thermoplastics films suitable for use as drafting materials comprise a filled film or a film composite having a filled layer, the fillers having a nominal particle size in the range 4 to 15 .mu.m and providing a roughened surface, and a matt layer adherent to the roughened surface comprising a binding resin and secondary filler particles having a nominal particle size in the range 1 to 15 .mu.m in an amount 10 to 100% by weight and having a coat weight of 0.05 to 2.0 g/m.sup.2. Also relates to a process for producing the films.
