Recording method by use of inks

A recording method which comprises imagewise applying (1) an aqueous ink comprising at least one dye selected from the group consisting of the following dyes (a) through (d) onto (2) a recording medium containing at least one component selected from the group consisting of water soluble metal salts in which the metal has a valence of 2 or more, alkyl amine salts, polyamines and quaternary ammonium salts, whereby to form an image on said recording medium,

• (a) a pyrazolone azo dye of the following formula I ##STR7## where M.sup.+ represents Li.sup.+, Na.sup.+, K.sup.+, Cs.sup.+, NH.sub.4.sup.+ or NR.sub.4.sup.1+ wherein R.sup.1 represents an alkyl group, X.sup.1 represents F, Cl, Br, I or hydrogen, and Y.sup.1 represents hydrogen, an alkyl group or --COO--M.sup.+ ;
• (b) a phthalocyanine sulfonate dye of the following formula II ##STR8## where M.sup.+ is the same as that defined in the formula I, and m m is an integer of 2 to 4;
• (c) a xanthene dye of the following formula III or IV ##STR9## where M represents Li, Na, K, Cs, NH.sub.4 or NR.sub.4.sup.1 wherein R.sup.1 represents an alkyl group, X.sup.2 represents Br, I or Cl, and Y.sup.2 represents Br, I or Cl;
• ##STR10## where M is the same as that in the formula III, and R.sup.2 represents hydrogen or an alkyl group;
• (d) an azo dye of the following formula V or VI ##STR11## where n is an integer of 0 or 1, X.sup.3 represents hydrogen or --NH.sub.2, Y.sup.3 represents hydrogen or --NHR.sup.1 wherein R.sup.1 represents an alkyl group, Z represents hydrogen, --OH or --COOM, and R.sup.3 represents hydrogen, an alkyl group or --SO.sub.3 M wherein M is the same as that defined in formula III;
• ##STR12## wherein X.sup.4 represents hydrogen, --SO.sub.3 M or --COOM in which M is the same as that defined in the formula III.
