Method for fluorescent image formation.

摘要

The present invention relates to a method for image formation, adapted for the formation of an image which, upon exposure to ultraviolet light irradiation, emits a plurality of fluorescent colors and/or a fluorescent color as a mixture of said fluorescent color, said method comprising the steps of providing two or more fluorescent inks respectively containing organic fluorescent agents which are substantially colorless upon visible light irradiation, but on the other hand, emit fluorescences having mutually different color tones in a visible region upon ultraviolet irradiation; and depositing said two or more fluorescent inks according to information on an image to be printed in a dot matrix manner onto an image formation region in a printing face so that dots of one color do not overlap with dots of another color.
