Paragraph 0015; 0016, (2017/04/03)
The invention discloses a solvent dye composition for solving the problems of poor high-temperature resistance and limited application range of solvent green 5 in the prior art. The solvent dye composition is composed of the following components in percentage by mass: 85-88% of 3, 9-perylenedicarboxylic acid bis(2-methylpropyl) ester and 12-15% of 3, 10-perylenedicarboxylic acid bis(2-methylpropyl) ester. The solvent dye composition disclosed by the invention is simple and reasonable in component ratio, good in high-temperature resistance and capable of completely replacing a solvent green 5; the melting point of the solvent dye composition can be up to 328-330 DEG C. The invention also discloses a preparation method of the solvent dye composition. The preparation method comprises the following steps: (1) preparing 3, 9-perylenedicarboxylic acid and 3, 10-perylenedicarboxylic acid; (2) preparing 3, 9-perylenedicarboxylic acid bis(2-methylpropyl) ester and 3, 10-perylenedicarboxylic acid bis(2-methylpropyl) ester; (3) compounding. The preparation method disclosed by the invention is simple in process step, strong in operability, low in cost and suitable for industrial production.
