Abstract
A thermal transfer ribbon which forms image resistant to offset is provided which comprises a substrate, a first coating which contains a non-hiding pigment and a binder and a second coating which contains a colored pigment and a binder. The binders in each coating are compatible so as to transfer simultaneously to a receiving substrate upon the application of heat while the pigments are sufficiently distinct so as to maintain distinct layers when transferred. In preferred embodiments, coating formulations which are water-rich and allow for the use of minimal organic solvent are used to form the thermal transfer ribbon. Labels having images resistant to offset are also provided which comprise two layers, one a protective layer and one a colored ink layer, each with high loadings of pigment.
