ABSTRACT:
Provided are light-absorbing polymers which contain backbone unsaturations and which are produced by knoevenagel condensation and which are useful for imparting color and/or ultraviolet light screening properties to thermoplastic resins. The polymeric colorants or UV absorbers may be added during the formation of the uncolored thermoplastic polymer or melt or solution blended with other thermoplastic polymers.
