19 Claims

1. An electromobility assembly comprising:

a voltage-conducting part having an operating voltage according to class B of ISO6469-3:2018; and

a high-voltage component in direct contact with or directly adjacent to the voltage-conducting part, wherein the high-voltage component comprises a polymer composition comprised of the following components:

(A) at least one polyamide, and

(B) a 10,10′-oxybis-12H-phthaloperin-12-one dye, wherein

the 10,10′-oxybis-12H-phthaloperin-12-one dye component (B) is present in an amount of 0.01 to 5 parts by mass per 100 parts by mass of the at least one polyamide component (A) which is sufficient to achieve (i) an orange color corresponding to a color distance ΔE<20 from the L*a*b* coordinates of a color number beginning with “2” in the RAL color chart, and (ii) reduced contact bleeding of the 10,10′-oxybis-12H-phthaloperin-12-one component (B) as compared to a high-voltage component having 12H-phthaloperin-12-one as component (B).
