Abstract:
1. A color filter comprising a colored layer as colored pixels provided on a transparent substrate, said colored layer containing a pyrrolo[3,4-c]pyrrole derivative produced by converting at least one ketopyrrole group in a pyrrolo[3,4-c]pyrrole of formula wherein A and B are each independently of the other a group of formula wherein R imidazolyl, pyrrazolyl, triazolyl, piperazinyl, pyrrolyl, oxazolyl, benzoxazolyl, benzothiazolyl, benzimidazolyl, morpholinyl, piperidinyl, or pyrrolidinyl; G is —CH 2 —, —CH(CH 3 )—, —CH(CH 3 ) 2 —, —CH═N—, —N═N—, —O—, —S—, —SO—, —SO 2 — or —NR 7 ; R 3 and R 4 are each independently of the other hydrogen, halogen, C 1 –C 18 alkoxy, or —CN; R 5 and R 6 are each independently of the other hydrogen, halogen, or C 1 –C 6 alkyl; and R7 is hydrogen or C 1 –C 6 alkyl; and D and E are each independently of the other a group of formula wherein, in the formulae (II), (III), and (IV), m, n, and p are each independently of one another a number of 0 or 1; X is C 1 –C 14 alkylene or C 2 –C 6 alkenylene; Y is a group —V— (CH 2 ) q —; Z is a group —V—(CH 2 ) r —; V is C 3 –C 6 cycloalkylene; q is an integer from 1 to 6; r is an integer from 0 to 6; R 8 and R 9 are each independently of the other hydrogen, C 1 –C 6 alkyl, C 1 –C 4 alkoxy, halogen, CN, NO 2 , unsubstituted phenyl or phenoxy, or phenyl or phenoxy which is substituted by C 1 –C 4 alkyl, C 1 –C 4 alkoxy, or halogen; and Q is hydrogen, CN, Si(R 8 ) 3 , a group C(R 12 )(R 13 )(R 14 ) wherein R 12 , R 13 , and R 14 are halogen, a group of formula wherein R a group SO R wherein X, Y, R said at least one ketopyrrole group being converted to wherein A may be B with the proviso that, if A is B, D is E; and R′ is C
