Title:
METHOD FOR PRODUCING INDIUM TIN OXIDE PARTICLES AND METHOD FOR PRODUCING CURABLE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2019/172151
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a method for producing indium tin oxide particles, which is capable of efficiently producing indium tin oxide particles that have adsorption in the near infrared region; and a method for producing a curable composition which contains indium tin oxide particles that have adsorption in the near infrared region, and which has low Abbe number and is useful for optical material applications. The present invention relates to a method for producing indium tin oxide particles, which comprises: a step for obtaining a precursor solution that contains indium and tin by heating an indium carboxylate having 1-3 carbon atoms and a tin carboxylate having 1-3 carbon atoms in a solvent that contains a carboxylic acid having 6-20 carbon atoms; a step for obtaining a reaction liquid that contains indium tin oxide particles by dropping the thus-obtained precursor solution into a solvent at 230-320°C, said solvent having a hydroxyl group and 14-22 carbon atoms, at a dropping rate of 1.0 mL/min or more; and a step for maintaining the thus-obtained reaction liquid for 60 to 180 minutes (inclusive) under the temperature condition of 230-320°C after the completion of the dropping of the precursor solution. The present invention also relates to a method for producing a curable composition which contains the thus-obtained indium tin oxide particles.
