The invention sublimable dyes having dyeing characteristics capable of reflecting the infrared region that is found in solar-approved for a coating sol of the metal chelate compound characterized in that that the coating on the base layer one side of the synthetic resin film mars dyes - metal relates to a dyeing coating solar light reflecting film and a production method using a chelate compound, at the same time salt fruiting to a substrate by a wet coating the reflective thin film showing a solar light reflecting characteristics are formed solar visible light, which accounts for 95% in the energy distribution by from the near infrared that is effectively blocking the 780nm ~ 1700nm area to the far infrared reflection from the sun light is strong during the day heat ray energy savings of high efficiency, so not a train only film of conventional solar absorption type reflective film to be transferred to the inside of the building photovoltaic train can provide a short film.
In addition, sublimable dyes according to the invention the dyeing speed by the carrier compound contained in the metal chelate compound, and serves to w complete dissolution of the chemical conversion dyes in high concentrations, also relax the molecular arrangement of the synthetic resin film base layer surface improved and also sublimable dispersion dyes should exhibit superior optical properties by the addition of a leveling agent, an organic solvent to a metal chelate compound, as well as grooves generated by the high surface tension difference with the substrate surface (crater) or spots (spot) and to the generation mitigate such or eliminate and provide good dyeing effect with no color difference variance, and this according to the invention sublimable disperse dye-by made of a metal chelate compound is reflux (reflux) synthesis, as a traditional simple equipment synthesis is possible, it is advantages of the benefits and the high solubility of chelating compounds which can reduce the manufacturing cost.
