を確認し得るものである。 It is an object of the present invention to provide a method for printing on the non-coated surface of the transfer sheet when the above-mentioned transfer sheet for creating secret documents and plain paper are overlapped and pressure printing is performed on the non-coated surface of the transfer sheet using pen pressure from a ballpoint pen or the like. At the same time, the microcapsules (hereinafter referred to as UV absorber-containing capsules) containing a solution of the UV absorber dissolved in a non-volatile vehicle on the coated surface are destroyed, and the UV absorber is transferred to the plain paper surface. It is used to obtain a latent image on plain paper. The obtained latent image is indistinguishable during normal handling, that is, in a visible state, and can only be confirmed by using a fluorescent inspection lamp.
