<p><P>PROBLEM TO BE SOLVED: To provide a method for producing a copper salt fine particle dispersion resin capable of suitably manufacturing optical materials having various sizes and obtaining optical materials having excellent heat resistance. <P>SOLUTION: The method for producing the copper salt fine particle dispersion resin includes: a step A for washing a mixture containing near-infrared absorbing copper salt fine particles having 1 nm to 10μm average particle diameter and a dispersant by using a solvent, and then precipitating the copper salt fine particles, and removing a supernatant liquid to obtain the copper salt fine particles; a step B for dispersing the copper salt fine particles obtained in the step A into a dispersion medium to obtain a dispersion liquid; and a step C for mixing the dispersion liquid with a resin to obtain the copper salt fine particle dispersion resin. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
