Abstract

The title compound is a soluble precursor ("latent pigment": t -BOC DPP) of diketopyrrolopyrrole pigment (DPP) that can be used for electronic and imaging applications in LCD color filters, ink jet and thermal printers. The regeneration and regenerated product of t -BOC DPP have been studied in terms of thermogravimetric and X-ray diffraction analyses, as well as IR and diffuse reflectance spectra on powdered substances. Transformation from t -BOC DPP to the parent DPP begins around 160° C and is completed around 180°C. A variety of colors (yellow via yellowish red to red) appear during the regeneration process, accompanied by evolution of CO2. Further color change also occurs due to aging and dispersion in vehicles. The color as well as the structure of regenerated DPP is slightly different from that of commercial DPP, and the heat and light stability is again not as high as that of the commercial product.
