  • MOLDED BODY HAVING MATT AND STRUCTURED SURFACE PROPERTIES
    Publication number: 20100272960
    Abstract: Composition for the production of mouldings having a matt and structured surface character, comprising a polymer matrix and crosslinked polymer particles, the polymer matrix comprising at least one acrylic polymer and the composition containing (i) first crosslinked polymer particles having a volume average of the particle size in the range from 30 ?m to 1500 ?m and (ii) second crosslinked polymer particles having a volume average of the particle size of less than 30 ?m, the difference between the refractive index of the first polymer particles and the refractive index of the polymer matrix, measured in each case at 25° C., being less than 0.015 as an absolute value and the difference between the refractive index of the second polymer particles and the refractive index of the polymer matrix, measured at 25° C., being greater than or equal to 0.015 as an absolute value.
