摘要： A process for producing a light guide plate includes producing a colorless transparent sheet from a colorless transparent material by extrusion with a polishing stack. A printed reflector film is laminated in-line to the colorless transparent sheet. The printed reflector film includes: a thermoplastic reflector film which is opaque white or translucent white and made of a thermoplastic material; and a colorless thermoplastic printed on the thermoplastic reflector film. There is no direct optical contact between the colorless transparent sheet and the thermoplastic reflector film. A glass transition temperature of the printed colorless thermoplastic is above 25° C. and below glass transition temperatures of the colorless transparent material of the colorless transparent sheet and of the thermoplastic material of the thermoplastic reflector film.

摘要： The invention relates to a method for producing a thermoplastic plastic film. According to said method, the thermoplastic plastic is melted and transported in an extrusion installation comprising an extruder, an extrusion nozzle with a wide-slot delivery opening and a chill roll, which is fixed to a roll system and then leaves the delivery opening of the extrusion nozzle in the form of a flat melted web. Said melted web is then applied to the chill roll and is cooled. The invention is characterised in that it uses an extrusion installation, in which the distance between the delivery opening of the extrusion nozzle and the surface of the cooled roll does not vary by more than +/−50 μm during the operating time. The invention also relates to a film of this type and to uses of the latter.
