Specific dye set for thermal ink-jet printing on plain and coated papers

摘要

A specific dye set, comprising Acid Yellow 23, Direct Red 227, and Acid Blue 9, yields true, vivid colors on specially coated paper and transparency, and yields true colors on uncoated or "plain" papers. This dye set, which is intended for 300 dpi thermal ink-jet printers, is a distinct improvement over a prior art dye set.
