Abstract: A treating solution containing an alkanediol (A) having 9 or more carbon atoms in which two hydroxy groups are respectively bonded to the carbon atoms that are non-adjacent to each other, at least one compound (B) of a polyvalent metal salt or a polyvalent amine, and water. An ink set for ink-jet printing is also described, which contains the treating solution and an ink that contains a coloring material and water. An ink-jet printing method using the treating solution includes applying the treating solution onto a printing medium to obtain a surface-treated printing medium, and forming images on a treated surface of the surface-treated printing medium in an ink-jet printing manner using an ink that contains a coloring material and water.
