PROBLEM TO BE SOLVED: To obtain a recording material capable of being printed repeatedly by ink jet printing without deteriorating its recording performance even in the case of using many times by incorporating mat or porous surface and a solvent receiving layer becoming opaque when no solvent exists and transparent when solvent is received. SOLUTION: The recording material comprises a mat or porous surface and a solvent receiving layer becoming opaque when no solvent exists and transparent when solvent is received. Thus, it is normally opaque but when transparent solvent is printed as ink by ink jet printing, a printed part of the layer holds the solvent in a recess of the matte surface or porous pores to become opaque so that the transparent printed part can be recognized with respect to the opaque non-printed part. That is, the surface receiving layer of the printed part is brought into contact with the solvent so that its refractive index is changed to be transparent. When it is left to stand after recording, the solvent is evaporated, the printed part becomes opaque, and hence can be again printed. |
