Abstract:
The present invention relates to organic coloring agents with a high color stability to weathering for thermoplastics. The invention furthermore relates to a polymer composition containing at least one thermoplastic and at least one organic coloring agent, preferably a combination of at least two organic coloring agents, of a specific structure. The invention moreover relates to the use of the coloring agents according to the invention for coloring polymer compositions, in particular for transparent formulations such as are required for the production of panes for use in buildings, motor vehicles and track vehicles or aircraft.
