| 摘要 |
The present invention relates to a method for evaluating dispersion of light-to-heat conversion materials among thermal transfer films and a thermal transfer film using the same. In the present invention, a thermal transfer film whose dispersion evaluation value, (ΔOD) calculated by chemical formula 1 is not more than 0.1 for the thermal transfer film is considered as a good dispersion of light-to-heat conversion materials among light-to-heat conversion layers. In the present invention, provided is a method for evaluating dispersion of light-to-heat conversion materials, which take less time to manufacture samples used for evaluating dispersion of light-to-heat conversion materials and take less time to evaluate the dispersion. In the present invention, a good dispersion means that thermal transfer film and, in particular, light-to-heat conversion layers have no stain. |
