PIGMENT COMPOSITION FOR PRINTING INK, METHOD FOR PRODUCTION THEREOF, AND METHOD FOR PRODUCTION OF PRINTING INK |
| 摘要 |
<p>The present invention provides a method for producing a pigment composition for a printing ink, which involves the step of dry-milling crude copper phthalocyanine using calcium carbonate having a specific property; a pigment composition for a printing ink; and a method for producing a printing ink using the pigment composition. Specifically, the present invention provides a method for producing a pigment composition for a printing ink, which involves the step of dry-milling crude copper phthalocyanine and calcium carbonate having a primary particle diameter of 20 to 1500 nm in the absence of a resin for a printing ink; a pigment composition produced by the method; and a method for producing a printing ink, which includes the steps of heating a mixture of a pigment composition, a resin for a printing ink and a solvent for the printing ink, and wet-milling the heated mixture.</p> |
