FIELD: chemistry.
SUBSTANCE: invention relates to liquids for holding aqueous ink on paper for jet printing. A liquid is described for holding water-based ink onto paper, containing a non-curling co-solvent in form of an inner salt, with a sp3-hybrid nitrogen cation and associated anionic charge, insulated on the oxygen anion, directly bonded to the sp3-hybrid nitrogen cation, or insulated between oxygen atoms of a carboxylate group, and is a compound which contains a group chosen from ammonium-N-oxide, N, N, N-trimethylglycinate and amino acid. Described also is use of the said liquid for holding ink on paper to prevent paper from curling during printing.
EFFECT: obtaining liquid for holding water-based ink onto paper, which efficiently reduces curling and deformation of printing paper.
