| 摘要 |
The present invention relates to a heat stable red pigment composition comprising a 2,9dichloroquinacridone (I) and a bis-(4,5,6,7-tetrachloroisoindolin-1-on-3-ylidene )-phenylene-1,4-diamine pigment (II) and a process for its preparation. The red pigment compositions are particularly useful for pigmenting engineering plastics. <IMG> I <IMG> II
