ISO-INDOLINE DERIVATIVES AND MACROMOLECULAR ORGANIC MATTERS PIGMENTED WITH SUCH COMPOUNDS

摘要

P Isoindolinic compounds having the formula BR/ (CF DRAWING IN BOPI) BR/ in which R represents an alkyl, phenyl, benzyl or phenylethyl radical, R1 and R2 each represent a hydrogen atom or of halogen or an alkyl or alkoxy radical, and X represents a radical corresponding to one of the formulas: ## STR3 ## in which A represents a radical -CN, alkoxycarbonyl or -CONH -R5, R3, R4 and R5 each represent hydrogen or a radical as defined for R, V represents -NH- or -O- and Z represents = O, = S, = N or = N (CN). / P P These iso-indolines with a nitrogen-substituted quinazolone radical are distinguished by their excellent properties as pigments, more particularly by a very high stability to atmospheric agents. / P
