| 摘要 |
The invention relates to a diketopyrrolopyrrole pigment of the formula (I) in which R10, R11, R12 and R13 independently of one another denote hydrogen, halogen, C1-C4 alkyl, C1-C4 alkoxy, cyano or phenyl, characterized by a first maximum in the frequency distribution (according to weight fractions) of the crystal sizes at or below 700 nm and at least one further maximum in the frequency distribution (according to weight fractions) of the crystal sizes which is at least 100 nm above the first maximum.
