摘要： Disclosed is a method of reducing a haze value in molding compositions including use of colorants selected from anthraquinone colorants, benzimidazolone colorants and perinone colorants. The molding compositions include at least one polyamide and at least one compound of the general formula (I) where x is 1, 2 or 3; R1 and R2 are mutually independently selected from hydrogen, linear C1-C7-alkyl, branched C3-C10-alkyl, unsubstituted or substituted C3-C12-cycloalkyl, unsubstituted or substituted C3-C12-cycloalkyl-C1-C4-alkyl, unsubstituted or substituted aryl and unsubstituted or substituted aryl-C1-C4-alkyl; and Z is selected from C3-C10-alkanediyl, unsubstituted or substituted arylene, unsubstituted or substituted arylene-C1-C4-alkylene-arylene, unsubstituted or substituted heteroarylene, unsubstituted or substituted heteroarylene-C1-C4-alkylene-heteroarylene, unsubstituted or substituted C5-C8-cyclo-alkylene, unsubstituted or substituted C5-C8-cycloalkylene-C1-C4-alkylene-C5-C8-cycloalkylene, unsubstituted or substituted heterocycloalkylene and unsubstituted or substituted heterocycloalkylene-C1-C4-alkylene-heterocycloalkylene.

摘要： The present invention relates to a process for producing a shaped body by selective laser sintering of a sinter powder (SP). The sinter powder (SP) comprises at least one semicrystalline polyimide and at least one nylon-6I/6T. The present invention further relates to a shaped body obtainable by the process of the invention and to the use of nylon-6I/6T in a sinter powder (SP) for broadening the sintering window (WSP) of the sinter powder (SP).
