manufacture example R2
[0311] 100 parts of diketopyrrolopyrrole red pigment PR254 (manufactured by Ciba Specialty Chemicals "IRGAPHOR RED B-CF"; R-1), 18 parts of pigment derivative (D-1), 1000 parts of ground salt, and 120 parts of diethylene glycol were put into a 1-gallon kneader made of stainless steel (manufactured by Inoue Seisakusho), and kneaded at 60° C. for 10 hours.
[0312] Put this mixture into 2000 parts of warm water, stir it with a high-speed mixer for about 1 hour while heating to about 80°C to make a slurry, repeat filtration and water washing to remove salt and solvent, and dry at 80°C for 24 hours. 115 parts of salt mill treated pigment (R2) were obtained.
