Abstract:
A thermal transfer ink ribbon comprising a base film having a surface, peel-off layer disposed on the surface, and thermally fusible ink layer disposed on the peel-off layer, and wherein said ink layer comprises a colorant, a thermally fusible resin binder having a melting point from 100.degree. C. to 150.degree. C., and from greater than about 10% to about 60% by weight, based on solids of the ink layer, of fine polymer particles selected from the group consisting of a condensation resin of benzoguanamine and formaldehyde, a condensation resin of melamine and formaldehyde, and a condensation resin of benzoguanamine, melamine and formaldehyde, said particles having an average diameter which is less than the thickness of the ink layer.
