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 ΔOD according to Equation 1. The thermal transfer film has good dispersion of the light-to-heat conversion material when the dispersion evaluation value ΔOD 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 ΔOD is greater than 0.1. ΔOD=|OD2−OD1|  Equation 1 OD1=−log(T2/T1)  Equation 2 OD2=−log(T3/T1)  Equation 3
