Despite higher costs, improved properties are driving growth for high performance pigments in a variety of printing markets and including packaging. Pigment red 254 (diketopyrrolopyrroles (DPP)) has been used as high performance pigment due to its unique brilliant red hue and high heat fastness. But DPP has a high manufacturing cost as a complicated process and waste water treatment problem. In this study, we synthesized red 254 DPP pigments in various condition such as solvent, temperature and derivative with simple process and low cost. Then Particle size and shape were evaluated by using transmission electron microscope (TEM), field emission scanning electron microscope (FE-SEM) and particle size analyzer (PSA). Finally, properties as dispersion sol were analyzed by tobiscan. As a result, we were able to produce high-performance red color pigments with various particle size and distribution. |
