Abstract
There is provided a printing method that can provide an image formed object which can suppress a change in density of a visible dye image and a lowering in fluorescence intensity and, at the same time, is free from concave/convex of the image surface and has a latent image invisible even under visible light. The printing method comprises a first step of forming a latent image of a fluorescent dye by thermal diffusion transfer; and a second step of providing a visible dye on the latent image by thermal diffusion transfer.
