AQUEOUS INKJET ACCEPTOR SOLUTION, INK SET INCLUDING ACCEPTOR SOLUTION, AND INKJET RECORDING METHOD USING INK SET

摘要

Provided are an aqueous inkjet acceptor solution having properties required for aqueous inkjet recording methods, particularly preventing nozzle clogging and having increased storage stability, and an ink set including the acceptor solution. The acceptor solution according to the present invention comprises (A) an organic acid salt having a carbon number of at least 3, (B) an inorganic salt and/or an organic acid salt having a carbon number of 2 or less, (C) a high boiling-point aqueous organic solvent having a boiling point of at least 180°C, and (D) water, wherein component (A) and/or component (B) is a polyvalent metal salt. Component (A) is not particularly restricted but is preferably a carboxylate, and could be a pantothenic acid, propionic acid or lactic acid calcium salt, a magnesium salt, a nickel salt, an aluminium salt, a boron salt or a zinc salt. Component (B) is not also not restricted but is preferably a chloride, a sulphate, a nitrate, a formate or an acetate, or a mixed salt of the same. Component (C) is a polyvalent alcohol, in particular is preferably an alkanediol in which both ends are not simultaneously a hydroxyl group.
