<p>Pigments are of formula (I): In (I), Z is -CO- or -SO2-; Q is H, Br or MeO; R is 1-4C alkyl opt. substd. by a Cl or a 1-4C alkoxy gp. or a gp. of formula (II) is which Y1 is H, Cl, 1-4c alkyl or alkoxy; Y2 and Y3 are independently H, Cl, CF3, 1-4C alkyl or alkoxy, 2-4c alkanoylamino or -COOR1-, in which R1 is 1-4 C alkyl opt. substd. by halogen or 1-4C alkoxy, or 5-6C cycloalkyl, benzyl or phenyl opt. substd. by halogen or 1-4C alkyl or alkoxy, Y2 and Y3 can together form an opt. Cl-substd. condensed benzene ring; X1 is H, Cl, 1-4C alkyl or alkoxy, 2-4C alkoxycarbonyl or phenoxy; R2 is H, 1-4C alkyl, or phenyl opt. substd. by halogen or 1-4C alkyl or alkoxy; X2 is H, halogen, 1-4C alkyl or alkoxy or phenoxy; n = 1 or 2, Z1 is -OCH2-, -C(CH3)=C-, -CONH- or -NH, providing that when R2 is alkyl or phenyl, at least one of Y1-Y3 is not H, and when R is alkyl, R2 must be H. (I) are used as red pigments for high mol. wt. natural and synthetic materials and have good fastness properties and high purity of tone.</p> |
