(DE) Farbausgewogener Kautschukverstärkter Kunststoff.
(EN) COLOR BALANCED RUBBER-REINFORCED PLASTIC
(FR) Matière plastique équilibrée en couleurs et renforcée de caoutchouc.
Abstract
(EN)
The color stability of certain rubber-reinforced polymeric compositions upon exposure to ultraviolet (UV) light is enhanced by incorporating a fadeable, yellow color balancer in an amount effective to reduce the overall color shift of the plastic due to exposure to UV light. The color balancer is an organic dye or pigment, preferably and anthraquinone dye, present in an amount (0.001 to 0.1 weight percent) below that at which it would be used to color the composition.
