PURPOSE: A heat transfer film is provided to increase transcription efficiencies of a transcription layer by equalizing OD values of a photovoltaic conversion layer within a specific wavelength. CONSTITUTION: A heat transfer film comprises an acryl class binder, pigments, dyes, and a photovoltaic conversion layer. Within a wavelength range of 750-1200 nano meters, the optical density(OD) deviation in the wavelength in which the pigments absorb is less than 1 and over 0. In the wavelength range of 750-1200 nano meters, the OD value of the photovoltaic conversion layer in the wavelength in which the pigments absorb is 1.0-5.0. 1-50 wt% of the pigment and the dye are included in the photovoltaic conversion layer based on the solid powder. The pigment and the dye has a weight ratio of 1 : 9 to 1 : 0.1. 0.5-29.9 wt% of the pigment is included in the photovoltaic conversion layer based on the solid powder. 0.5-29.5 wt% of the dye is included in the photovoltaic conversion layer based on the solid powder. |
