    Abstract: A dyeing method in which a transparent resin body having a surface applied with a dye is heated to fix the dye to the transparent resin body comprises a heating step of irradiating a laser beam having a wavelength less likely to be absorbed by the dye toward the transparent resin body applied with the dye on the surface while relatively scanning the laser beam with respect to the transparent resin body to heat a to-be-dyed region of the transparent resin body to fix the dye, wherein the laser beam is irradiation to heat by changing a laser beam irradiating condition with respect to a portion of the transparent resin body to be heated so that a heating temperature on the transparent resin body by irradiation of the laser beam is substantially equal throughout an entire area of the to-be-dyed region.

    Abstract: A dyeing device dyes a resin body by vaporizing and depositing a sublimation dye adhered to a dyeing base to a resin body and fixing the dye to the resin body. The dyeing device lowers the pressure inside a closed chamber that closes the periphery of the resin body by a pump. In the state where the adhesion surface of the dyeing base to which the dye is adhered faces the resin body without contact, by heating the dye adhered to the dyeing base inside the closed chamber of which the pressure is lowered, the dye is sublimated, vaporized, and deposited on the resin body. The pressure inside the closed chamber is raised higher than the pressure at the vaporizing and depositing time. By irradiating the resin body on which the dye is vaporized and deposited with electromagnetic wave, the resin body is heated and the dye is and fixed.

    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.
