| titleOfInvention | Method for producing silica coated organic pigment with excellent light and heat resistance |
| abstract | A method for producing a silica coated organic pigment is disclosed. The method for preparing silica coated organic pigments according to the present invention comprises (a) a weight ratio comprising a main body comprising water, a first pigment intermediate, a strong acid, and sodium acetate, and a binder including water, sodium hydroxide, a second pigment intermediate, and glacial acetic acid. Mixing in a ratio of 1: 1 to 1: 3 to form a slurry and then neutralizing it; (b) adding an alkaline substance to the product of step (a); (c) adding a metal compound to the result of step (b); (d) neutralizing the result of step (c), followed by filtering and washing to obtain an intermediate product; (e) dispersing said intermediate product in water; (f) micronizing after adding an alkali metal salt to the product of step (e); (g) adding the resultant of step (f) to a reactor, heating to 80-100 ° C., and then adding and stirring sodium silicate, a coupling agent and a pH adjuster; And (h) neutralizing the resultant of step (g), followed by filtering and washing. |
