Abstract
The present disclosure provides metallic LEP inks and associated methods. In one example, a method of manufacturing a metallic LEP ink having reduced impurities can comprising adding a metallic pigment slurry and a resin to a stainless steel attritor, adding ceramic grinding beads to the attritor, and grinding the metallic pigment and the resin to form the metallic LEP ink.

A method of manufacturing a metallic LEP ink having reduced impurities, comprising:
- adding a metallic pigment slurry and a resin to a stainless steel attritor;
- adding ceramic grinding beads to the attritor;
- and
- grinding the metallic pigment and the resin to form the metallic LEP ink.
A method of reducing impurities in a metallic LEP ink, comprising
- adding a metallic pigment slurry and a resin to a stainless steel attritor;
- adding ceramic grinding beads to the attritor;
- and
- grinding the metallic pigment and the resin to form the metallic LEP ink;
- wherein the reduced impurities are measured as a function of brightness of the metallic LEP ink compared to a comparable LEP ink;
- the comparable LEP ink having the same components and same amounts as the LEP ink but produced by a second attritor with second grinding beads made from the same material;
- the metallic LEP ink being brighter than the comparable LEP ink.
A metallic LEP ink having reduced impurities, comprising:
- a metallic pigment;
- a resin;
- and
- a solvent;
- wherein the metallic LEP ink is produced by a stainless steel attritor and ceramic grinding beads;
- wherein the reduced impurities are measured as a function of brightness of the metallic LEP ink compared to a comparable LEP ink;
- the comparable LEP ink having the same components and same amounts as the LEP ink but produced by a second attritor with second grinding beads made from the same material;
- the metallic LEP ink being brighter than the comparable LEP ink.
