Abstract
Abstract A thermal transfer material, comprising: a support, and a first ink layer and a second ink layer respectively containing a heat-fusible material disposed in the order named on the support. The second ink layer includes domains of at least two species. The thermal transfer material provides a transfer image of high density and clear edges even on a recording medium having poor surface smoothness.
