Abstract
An ink sheet for making thermal transfer colour recordings, with practically acceptable high speed and high resolution using a semiconductor laser beam, comprises a support film coated with an opto-thermal conversion layer to generate heat by absorbing the laser beam, and an overlying thermal melt transfer ink layer, wherein the opto-thermal conversion layer is 5 .mu.m thick or less, and in the wavelength region of 700 nm to 900 nm has a laser beam transmittance of 5% or less.
