Abstract:
A laser thermal transfer recording method comprising the steps ofsuperposing a laser thermal transfer ink sheet having a light-heat conversion layer and an ink layer on a laser thermal transfer image receiving sheet having a thermoplastic layer and an image receiving layer; contacting with a vacuum a surface of the ink layer of the ink sheet with the surface of the image receiving layer of the image receiving sheet; thermally transferring a part of the ink layer to the image receiving layer by light-heat conversion of laser light irradiated from the ink layer side; and peeling off the ink sheet from the image receiving sheet, wherein Vicat softening point of the resin of the thermoplastic layer is not more than 80Â° C., and one of the image receiving layer and the ink layer contains a matting agent having a particle diameter larger than the thickness of the layer containing matting agent, the projection height of the matting agent is less than 3.5 &mgr;m and the frequency of the projections is from 400/mm2 to 4,000/mm2, and peeling angle of the ink sheet and the image receiving sheet is controlled at an angle less than 30Â°.
