    Abstract

    The present invention relates to a process for simultaneous colouring and U.V. stabilisation of polymers. The process comprises colouring and stabilising the polymer with dyed lignin. With this process different colour shades may be obtained ranging from light shades through to rich dark shades, depending on the concentration of dyed lignin. The polymers e.g. polyolefins obtained have a glossy finish. Further, the use of the dyed lignin as the pigment composition also gives the polymer that has been coloured a simultaneous enhancement of stability to U.V. radiation.
