Electrophotosensitive materials for migration imaging processes

Claim 1

An electrophoretic migration image comprising a material having the structure: ##STR61## wherein: M and N may be zero, one or two; L 1 , L 2 , L 3 , L 4 , L 5 , L 6 and L 7 may be cyano, hydrogen, substituted or unsubstituted alkyl, alkoxy, aralkyl, aryl or heterocycyl and in addition any two of L 1 , L 2 and L 3 and any two of L 4 , L 5 , L 6 and L 7 may together represent the elements needed to complete a carbocyclic or heterocyclic ring having from 5-12 carbon atoms; A 1 may be the same as A 2 and in addition may represent an aryl or diarylamino aryl substituted, or unsubstituted aryl group or a substituted or unsubstituted heterocyclic nucleus such as thiophene, benzo[b]thiophene, naphtho[2,3-b]thiophene, furan, isobenzofuran, chromeme, pyran, xanthene, pyrrole, 2H-pyrrole, pyrazole, indolizine, indoline, indole, indazole, carbozole, pyrimidine, isothiazole, isoxazole, furazan, chroman, isochroman, 1,2,3,4-tetrahydroquinoline, 1,2-dihydro-4H-pyrrolo[3,2,1-ij]quinoline; 4H-pyrrolo[3,2,1-ij]-quinoline; 1,2,5,6-tetrahydro-4H-pyrrolo[3,2,1-ij]quinoline; 1H,5H-benzo[ij]quinolizine; 2,3-dihydro-1H,5H-benzo[ij]quinolizine; 2,3-dihydro-1H,5H-benzo[ij]-quinolizine and 2,3,6,7-tetrahydro-1H,5H-benzo[ij]quinolizine; 10,11-dihydro-9H-benzo[a]xanthen-8-yl; 6,7-dihydro-5H-benzo[b]pyran-7-yl and pyrrolo[2,1-b]-benzothiazole; A 2 represents a basic substituted or unsubstituted heterocyclic nucleus selected from the group consisting of substituted or unsubstituted imidazole, thiazole, benzothiazole, naphthothiazole, thianaphtheno-7',6',4,5-thiazole, oxazole, benzoxazole, naphthoxazole, benzoselenazole, naphthoselenazole, thiazoline, 2-quinoline, 4-quinoline, 1-isoquinoline, benzimidazole, 2-pyridine, 4-pyridine, pyrrolo[1,2-a]pyridine, 3H-indole, tetrazole, and acenaphthothiazole; and B 1 and B 2 represent cyano, cyanoaryl, carboxy, alkoxycarbonyl, aryloxycarbonyl, alkylsulfonyl, acyl, arylcarbonyl, benzofuroyl, nitro, nitro-substituted aryl, sulfonyl, fluorosulfonyl, trifluoromethylsulfonyl, carbamoyl, arylcarbamoyl, and alkylcarbamoyl, or B 2 may be combined with ═CL 4 -CL 5 ═ or ═CL 6 -CL 7 ═ to provide sufficient atoms to form a substituted pyrindine nucleus.
