A ternary solid soln. consists of: (a) 50-97 wt. % of a quinacridone quinone of formula (I); (b) 2-30 wt. % of a pyrrolo [3,4-C] pyrrole of formula (II); and (c) 1-20 wt. % of a component of formulae (III) or (IV) chosen from 2-anilino acridone, a 5,6,7,8-tetra-hydro-2-anilino acridone, 2-phenoxy acridone and/or a 5,6,7,8- tetrahydro-2-phenoxy acridone. Also claimed are: (i) a quaternary solid soln. consisting of: (a)' 40-96 wt. % of a quinacridone- quinone of formula (I); (b)' 1-45 wt. % of a quinacridone of formula (V); and (c)' part (b); and (d)' part (c); (ii) a pigment compsn.; (iii) a method of colouring a high molecular wt. organic material by incorporating into it an effective amt. of a ternary solid solution of (a)-(c): R = H, halogen, 1-4C alkyl; x, y = 1-2. R1, R2 = H, halogen, 1-5 C alkyl, 1-5 C alkoxy, SR3, -N()1-5 C alkyl)2, -CF3, -CN, R3 = 1-5 C alkyl; R4, R5 = H, halogen, 1-5 C alkyl, 1-5 C alkoxy, -SR3, -CN; A = H, NH; R' = H, halogen, 1-4 C alkyl; and R" = H, halogen 1-4 C alkyl, tri-fluoromethyl; and (iv) a method of colouring a high mol. wt. organic material comprising incorporating a quat. solid soln. of (a)'-(d)'.
