<P>PROBLEM TO BE SOLVED: To provide an inkjet recording method which enables a printing image with excellent water resistance, resistance to scuffing and feeling of gloss to be formed in an optical recording medium such as CD or DVD. <P>SOLUTION: This inkjet recording method is to make a colored ink containing a coloring material and a transparent ink not containing a coloring material adhere to a printable region for the optical recording medium with at least an optical recording layer formed on a light transmitting substrate, with the help of an inkjet recording process. The transparent ink contains not less than one kind of cationic substance selected from the group consisting of a cationic resin and a cationic surfactant. In addition, the transparent ink can contain a luminescent substance which has no absorptive wavelength in a visible light region and shows a luminescence in a visible light region under a specific light source. Thus the transparent ink is effective for forgery prevention in the recording medium. <P>COPYRIGHT: (C)2007,JPO&INPIT |
