Advances in New Technology for the Organic Pigment Industry

Novel chemical structures, application properties, novel synthesis and processing techniques of organic pigments are reviewed with 41 references. DPP pigments with improved application properties and new formulations have been developed; the color strength and stability of benzimidazolone-dioxazine pigments have been improved by combining two structures into one molecule. Nano pigments and latent pigments that can be obtained by pigmentation techniques and processing, including pigmentation in water under pressure, plasma surface modification, microwave irradiation synthesis, etc., will be emphasized by the organic pigment industry. Six noteworthy technical problems, including the development of novel chromophores, surface modifications, usage of special auxiliaries, the concept of "Core Technologies" including chemical structure, and particle size, shape, distribution, and polarity (S&PPP), are introduced and discussed.
