  • Method of producing photochromic resin body and method of producing function-adding base body
    Patent number: 11623419
    Abstract: A method of producing a photochromic resin body includes a first step, a second step and a third step. In the first step, a sublimable photochromic dye having sublimability is applied to a base body so as to obtain a function-adding base body. In the second step, the function-adding base body obtained in the first step is set to face a resin body, the function-adding base body is heated to sublimate the sublimable photochromic dye applied to the function-adding base body, and the sublimable photochromic dye is deposited on the resin body. In the third step, the resin body on which the sublimable photochromic dye is deposited in the second step is heated to fix the sublimable photochromic dye on the resin body.
