摘要： A recordable optical recording medium is provided enabling the light transmission layer to be a single layer, the inhibition of peeling of the recording layer even when stored in high-temperature/high-moisture conditions, and the reduction of degradation of the recording/reproduction characteristics. A recordable optical recording medium provided with a substrate, and, on the substrate in the following order, a reflective layer, a recording layer, a protective layer, and a light transmission layer. The optical recording medium has the recording layer formed thereon using an organic dye obtained by adding a highly waterproof, low hydrophilic organic dye to a triazole-based azo metal complex dye.

摘要： The invention relates to a method for producing a coloured 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 outlet and a chill roll which is fixed to a roll frame, and then leaves the outlet of the extrusion nozzle in the form of a flat, coloured melted web. Said coloured melted web is then applied to the chill roll and is cooled. The invention is characterised in that the chill roll has a rotational accuracy of +/- 10 µm or less and that the average distance between the outlet of the extrusion nozzle and the chill roll does not vary by more than +/- 25 µm during operation. The invention also relates to the coloured film of this type and to the uses thereof as a coloured film for a data carrier.
