Abstract:
A recording method wherein, when record is performed on a recording medium by use of an anionic or cationic ink and a liquid composition, the ink containing a coloring material, the liquid composition containing fine particles in a dispersed state, the surfaces of the fine particles being charged with a polarity opposite to that of the ink,M, D, Ka, tw and t satisfy the relation of t&leq;(107Ã—M&it;â€ƒ&it;DK&it;â€ƒ&it;a)2+t&it;â€ƒ&it;wwhere M (pg/&mgr;m2) is the amount of the ink supplied to the recording medium per unit area, D (%) is the concentration of the coloring material of the ink, Ka (&mgr;m/msecÂ½) is the absorption coefficient of the ink in the recording medium, tw (msec) is the time required for the ink to moisten in the recording medium, and t (msec) is the time required for the liquid composition to make contact with the supplied ink after the ink is supplied to the recording medium.
