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.

Abstract: A dye-deposited base body manufacturing apparatus manufactures a dye-deposited base body. The dye-deposited base body is used in a dyeing step of dyeing a resin body. A dye to be transferred to the resin body is deposited to a base body. The dye-deposited base body manufacturing apparatus is provided with a printing device, a conveyance device, and a base body movement device. The printing device prints a dye for dyeing the resin body on the base body. The conveyance device conveys a dyeing tray on which the dye-deposited resin body on which the dye is printed by the printing device is placed. The base body movement device moves the dye-deposited base body from a printing position by the printing device to a side of the conveyance device.
