Abstract

The invention relates to composite bi-oriented semi-crystalline polyester films comprising a filled or unfilled thick film and, on at least one of the surfaces of the layer (A), a coextruded polyester layer (3) thinner than layer (A), a coextruded polyester layer (3) thinner than layer (A) with the following features: Rt </= 3 mu m, Rt/Ra </= 10, and containing a filler with a mean diameter D 50 of 1.5 to 2.5 mu m and a monodispersity I of D 75 - D 25 </= 1.2. These films may be used as protective foils for the photopolymerisable layers of photopolymerisable components.
