Abstract
A thermal transfer material, comprising a support, and a heat-transferable ink layer. The heat-transferable ink layer includes at least two species of domains of heat-fusible materials. The thermal transfer material provides a transfer image of high density and clear edges even on a recording medium having poor surface smoothness, particularly when peeled off the recording medium within 50 milli-seconds after the heat application.
Claims18
A thermal transfer material comprising:
- a support, and a heat-transferable ink layer containing heat-fusible material disposed on the support, said heat transferable ink layer comprising at least two species of domains of different heat fusible-materials in the form of resin particles, and a colorant;
- each of said resin particles comprising a resin selected from the group consisting of:
- polyamide resins, polyester resins, epoxy resins, polyurethane resins, acrylic resins, vinyl acetate resins, polyvinyl pyrrolidone, polyvinyl chloride resins, cellulose resins, polyvinyl alcohol resins, petroleum resins, terpene resins, rosin derivative resins, courmarine-indene resin, phenol resins, polystyrene resins, polyolefin resins, polyvinyl ether resins, polyethylene glycol resins, natural rubbers, styrene-butadiene rubber and isoprene rubber.
A thermal transfer recording method comprising the steps of:
- providing a thermal transfer material comprising a support and an ink layer of at least two species of domains of heat-fusible material in the form of particles, and a colorant disposed on the support;
- superposing the thermal transfer material on a recording medium so that the ink layer contacts the recording medium;
- supplying a heat pulse to the thermal transfer material from the support side;
- and
- peeling the thermal transfer material off the recording medium within 50 milli-sections after the heat application to cause a selective transfer of the ink layer to the recording medium.
