The invention relates to the use of compounds of the formula
1
in which R
1
, R
2
, R
3
and R
4
independently of one another are hydrogen, halogen, R
6
, OR
6
or SR
6
, R
5
is hydrogen or linear or branched C
1
-C
12
alkyl, benzyl or phenethyl, and R
6
is an apolar group which is unsubstituted or substituted one or more times by halogen or by OC
1
-C
6
alkyl, with the proviso that if R
5
is hydrogen, R
1
, R
2
, R
3
or R
4
is R
6
, OR
6
or SR
6
, as additives in the pigmentation of partially crystalline plastics, especially those processed by injection moulding, with pigments containing at least one each of groups
2
which are joined to one another as
3
or are in conjugation with one another.
Preferred pigments are quinacridone pigments, disazo condensation pigments, isoindolinone pigments and pyrrolo[3,4-c]pyrrole pigments, especially pyrrolo[3,4c]pyrrole pigments.
Corresponding formulations and novel compounds are likewise claimed.
By these means it is possible to avoid warping.

, R
2
, R
3
和 R
4
分别为氢、卤素、R
6
、OR
6
或 SR
6
, R
5
是氢或线性或支链 C
1
-C
12
烷基、苄基或苯乙基,而 R
6
是未被取代或被卤素或 OC 取代一次或多次的烷基。
1
-C
6
烷基,但如果 R
5

1
, R
2
, R
3
或 R
4
是 R
6
