POLYMERIZABLE DIKETOPYRROLOPYRROLES AND POLYMERS PREPARED THEREWITH

摘要

1,4-Diketopyrrolopyrroles of the formula (see fig. I) (?) in which A and B independently of one another are a group of the formula (see fig. II) , or (see fig. III) , R1 is a long-chain radical containing a reactive group capable of polymerization, and R2 is C1-C6alkyl, (see fig. IV) or R1. For the definition of the radicals R3-R9 refer to claim 1. The novel diketopyrrolopyrroles are suitable for preparing coloured polymers with unexpectedly advantageous colour effects.
