Dyes for Writing, Drawing, and Marking

Similar to ink-jet dyes, dyes used for writing, drawing and marking materials fall into two categories water soluble dyes for aqueous inks and dyes for solvent inks [1,5]. Dyes are listed according to application in Tables 5.9-5.13. Many of these dyes can also be used for ink jet applications. However, ink jet dyes have to satisfy more stringent criteria with regard to purify and salt content.
