Abstract (en)
[origin: EP0704766A1] Transparent elements for use in electrostatic copiers comprise: (1) a composite polyester support (S) comprising: (a) a relatively thick layer (A) of semi-crystalline polyester; and (b) on face(s) of the layer (A), a thin layer (B) of a polyester that is the same or different to the polyester constituting layer (A); and (2) a primer coating (P) less than or equal to 0.3 mu thick on the face(s) of the support to promote adhesion of the toner to the support, comprising an acrylic polymer having a glass transition temp. Tg of 10-50 degrees C., a content of free-COOH functions of less than 50 millimoles per 100 g acrylic polymer.
