Abstract
A heat-sensitive transfer material capable of giving transferred images of good printed letter quality even on a recording medium with poor surface smoothness, is provided by forming, on a support, a heat transfer layer comprising a micro-network porous resin structure of a thermoplastic resin and a heat-fusible gel ink contained in the micropores of the porous resin structure. The heat-fusible gel ink comprises a colorant, an oil incompatible with the thermoplastic resin and a gelation agent for the oil.
