Patent number: 6890977Abstract: The invention relates to the use of compounds of the formula R1, R2, R3 and R4 independently of one another are hydrogen, halogen, R6, OR6 or SR6, R5 is hydrogen or linear or branched C1-C12alkyl, benzyl or phenethyl, and R6 is an apolar group which is unsubstituted or substituted one or more times by halogen or by OC1-C6alkyl, with the proviso that if R5 is hydrogen, R1, R2, R3 or R4 is R6, OR6 or SR6, as additives in the pigmentation of partially crystalline plastics, especially those processed by injection moulding, with pigments containing at least one each of groups which are joined to one another as 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[3,4-c]pyrrole pigments. Corresponding formulations and novel compounds are likewise claimed. By these means it is possible to avoid warping.Type: GrantFiled: October 29, 2003Date of Patent: May 10, 2005Assignee: Ciba Specialty Chemicals CorporationInventors: Franck Rey Flandrin, Guo-Hua Hu, Philippe Bugnon, Zhimin Hao
