| 摘要 |
<p>The invention relates to iminoisoindolinone pigments of the formula wherein X is halogen, Y and Z are halogen, C1-C4alkoxy, or aryloxy, R1 and R2 are hydrogen, halogen, C1-C2alkyl or C1-C2alkoxy, and A is phenyl which can be substituted by halogen, trifluoromethyl, C1-C2alkyl, C1-C2alkoxy, or by a group of the formula -CONHR3 or -NHCOR4, wherein R3 is hydrogen, C1-C2alkyl, or phenyl which can be substituted by halogen, methyl, methoxy or trifluoromethyl, and R4 is phenyl which can be substituted by halogen, methyl or methoxy, or is C1-C2alkyl, or A is a heterocyclic radical. These pigments are distinguished by particularly excellent colour strength and fastness to migration and are suitable for pigmenting organic material of high molecular weight.</p> |
