<p>PURPOSE:To prevent the blurring of image in order to raise its clearness by recording a print with a liquid containing a reactive dye on a recording material previously treated with a nonvolatile amine. CONSTITUTION:A liquid, obtained by dissolving 0.01-10wt% nonvolatile amine, e.g., undecylamine, in a solvent, e.g., water, an alcohol, etc., is coated on a paper and then dried to obtain a recording paper. On the other hand, a recording liquid, containing 0.1-20wt% a reactive dye, e.g., Procion Black H-G, 10-95wt% water, together with, as needed, an alcohol, a glycol, or a surfactant, is regulated its pH to 2-7 by the addition of a pH regulator. The recording liquid 7 is supplied through a supply pipe 8 from the liquid tank, during the period thereof its discharge pressure is controlled by a signal treating means 10 and a recording is made effectively on the surface of the recording material 12.</p> |
