Use of thermoplastic molding compositions comprising, as essential components,n A) a polyester, B) from 20 to 200 mmol/kg of polyester A) of at least one compound of the general formula (I) nn n n n n n n n n n n n where n respectively independently at any position n -A 1 - is —NR—, —O—, —S—, —CH=A 4 - where R is H or C 1-6 -alkyl, A 4 is N or CH n A 2 is COOX or OX, where X is Li, Na, K, Rb, Cs, Mg/2, Ca/2, Sr/2, Ba/2, Al/3 n A 3 is C 1-6 -alkyl, C 6-12 -aryl, O 7-13 -alkaryl, C 7-13 -aralkyl, O—C 1-6 -alkyl, O—C 6-12 -aryl, O—C 7-13 -alkaryl, O—C 7-13 -aralkyl, COOX′, OX′, SX′, SO 3 X′, where X′ is H or X, S—C 1-6 -alkyl, S—C 6-12 -aryl, NR 2 , halogen, NO 2 , n n is an integer from 1 to 4, and n m is an integer from 0 to 4−n, where m=1, if A 3 =NO 2 , n with the proviso that the number of mmol is based on the group(s) COOX and OX and SX′ where X′═X, to the extent that these are present in the compound of the general formula (I), and also moreover n n n C) from 0 to 230% by weight of further added substances, based on the weight of component A),n nfor producing laser-transparent moldings of any type. |
