Zusammenfassung:The present invention relates to a polyamide molding compound comprising the following components or consisting of these components: (A) 50 to 95 wt% of a mixture comprising the specific polyamides (A1) and (A2); (B) 5 to 50 wt% of at least one glass filler having a refractive index in the range from 1.540 to 1.600; (C) 0 to 10 wt% of at least one additive; wherein the weight proportions of the components (A) to (C) add up to 100% by weight; wherein the content of (A1) in the mixture (A) is > 50 wt%, if the ratio is ?2/?1 > 1 and the content of (A2) in the mixture (A) is > 50 wt%, if the ratio is ?2/?1 ? 1, where ?1 = n (?1) - n(B) applies and ?2 = n(B) - n(A2) applies; wherein the transparent polyamides (A1) and (A2) have a transparency of at least 90% and a haze of at most 3%; and wherein the mixture (A) has a transparency of at least 88% and a haze of at most 5%. The present invention additionally relates to molded bodies composed of these polyamide molding compounds.
