ABSTRACT:
A color sheet comprising; a flexible substrate or film; and a dye layer formed on the substrate including a sublimating dye of yellow, magenta or cyan and a near infrared absorbing pigment with a near infrared absorption without a substantial visible absorption.
A color transfer method comprises the steps of: preparing a color sheet above mentioned; abutting the dye layer of the color sheet onto an image receiving sheet to be printed; and irradiating an optical laser beam to the dye layer, the laser beam having a wavelength in the near infrared region absorbed by the near infrared absorbing pigment, whereby a light energy absorbed by the near infrared absorbing pigment is converted into a heat energy thereby sublimating the sublimating dye and transferring the sublimated dye onto the image receiving sheet arranged so as to face the dye layer.
As a result, a recording speed and a resolution are remarkably improved with the color sheet and the color transfer method using it.
