Quinacridone nanoscale pigment particles and methods of making same |
| abstract |
A process for preparing coated nanoscale quinacridone pigment particles, includes: mixing a quinacridone pigment precursor or crude quinacridone pigment with a first solution including an acid to form nanoscale quinacridone pigment particles; adding the first solution and formed nanoscale quinacridone pigment particles into a second solution including deionized water to form a third solution and to precipitate the nanoscale quinacridone pigment particles; and washing the precipitated nanoscale quinacridone pigment particles in a fourth solution including a surface additive compound, whereby the surface additive compound coats the nanoscale quinacridone pigment particles; wherein the surface additive compound is a rosin compound. |
