  • METHOD FOR EVALUATING DISPERSION OF MATERIAL FOR LIGHT TO HEAT CONVERSION IN THERMAL TRANSFER FILM AND THERMAL TRANSFER FILM USING THE SAME
    Publication number: 20150030884
    Abstract: A method for evaluating dispersion of a light-to-heat conversion material in a thermal transfer film includes calculating optical densities OD1 and OD2 of the thermal transfer film according to Equations 2 and 3, and calculating a dispersion evaluation value ?OD according to Equation 1. The thermal transfer film has good dispersion of the light-to-heat conversion material when the dispersion evaluation value ?OD is 0.1 or less, and the thermal transfer film has poor dispersion of the light-to-heat conversion material when the dispersion evaluation value ?OD is greater than 0.1.
