A process can be used for manufacturing a coloured moulding composition with an improved optical appearance and a particularly high thermal stability. The process involves providing a thermoplastic polymer and adding a colouring preparation, or a liquid composition or a master batch containing the colouring preparation. Injection moulded parts and extruded parts can be composed of the coloured moulding composition.
