Abstract
A transparent, amorphous polyamide molding compound contains polyamides which are formed by polycondensation of a linear aliphatic dicarboxylic acid with a cycloaliphatic diamine and also blends thereof, and also additives and/or colorants. The linear aliphatic dicarboxylic acid is selected from dicarboxylic acids with 17 to 21 C atoms and the diamine is bis(3-methyl-4-aminocyclohexyl)methane (MACM) and cross-linking additives, in the case of the additives, and photochromic colorants, in the case of the colorants, are precluded.
