A fabric ribbon having multicolored regions has coloring matter in the regions of only flushed pigments in a liquid vehicle. Flushed pigments do not migrate between colored regions under normal conditions, and therefore mixing of the colors is avoided without alteration of the fabric or use of a fabric with special characteristics or regions. Flushed pigments have very small article size and perform like dyes with respect to replenishing the ribbon for good ribbon life. Yet, the ribbon colors do not bleed together, a characteriztic of pigments.

Multicolored fabric printing ribbon including nonbleeding, nonmigrating

A matrix transfer medium with the binder being an aliphatic polyester polyurethane. This is formed directly on an untensilized polyethylene terephthalate film substrate. Porous magnesium silicate in minor amounts as a filler beneficially controls ink flow at printing. Overall good performance as to both ribbon feed and printing is realized.
