Abstract
A hot-melt ink composition for an ink jet printer comprising from 10 to 65% by weight of a polyamide resin, from 5 to 60% by weight of a fatty acid amide, from 5 to 40% by weight of a glyceride, and up to 5% by weight of a colorant. The composition is excellent in transparency to provide a highly transparent ink image on an OHP sheet.
