What pigments are used in printer ink?


Recommended Posts

Good question. Most of my searching only turns up offset printing stuff.

This is as close as I could get:

Title:

Potassium N-methyl-N-oleoyl taurate as a dispersant in pigmented ink jet inks

Document Type and Number:

United States Patent 5985017

Abstract:

An ink jet printing method is described. It comprising the steps of: providing an ink jet printer that is responsive to digital data signals; loading the printer with ink receptive substrates; loading the printer with an aqueous ink jet ink, said ink A) comprising a pigment, an aqueous carrier and potassium N-methyl-N-oleoyl taurate; and B) having a surface tension of 20 to 60 dynes/cm at 25

Thanks for that info, I was talking about ink jet printers. Organic inks are no good for me. I was hoping that some of the pigments would survive the ceramics firing process like traditional pigments would but it looks like no dice.

I do believe the Epson archival inks are pigment based.
