    摘要： Novel crystalline modifications (eta, theta, iota, kappa) of the C.I. Pigment Yellow 181, obtained when one of the known phases or another inventive phase of said pigment is treated with specific solvents. The novel crystalline phases are characterized by yellow shades and excellent coloring properties.

    摘要： Process for phase conversion of a methyl-substituted, benzimidazolone-fused dioxazine pigment of composition C22H12Cl2N6O4 having the formula (1) or of an isomer or tautomer thereof, which comprises treating the pigment of formula (1) with certain organic solvents. In the course of this phase conversion, 4 novel crystal polymorphs are formed which are called phases II, IV, V and VI and are characterized by means of their X-ray powder diagrams. The novel polymorphs are of low solubility and feature good fastness properties and violet colorations. The novel crystal polymorphs are suitable for pigmenting coating materials, plastics, printing inks, aqueous or solvent-based pigment preparations, electrophotographic toners and developers, powder coating materials, inks, preferably inkjet inks, and color filters, and for coloring seed.

    摘要： C.I. Pigment Red 53:2 is obtained in new crystal modifications (epsilon, zeta, eta, theta, iota, kappa, lambda, nu, xi, omicron, pi and rho phases) by heating any other phase of this pigment in certain organic solvents and reprecipitating the pigment. The new crystal phases differ from one another in rheology and coloristics.
