<p>PURPOSE:To obtain the subject ink using neither an organic solvent nor a surfactant, not deteriorating an operation environment, having adhesiveness to a material to be processed and blast resistance, comprising a water-dispersible polymer having the specific lowest specific minimum film-forming temperature and a prescribed water-soluble polymer. CONSTITUTION:This ink comprises (A) a water dispersion of at least one polymer selected from the group consisting of a polyvinyl acetate-based resin, an ethylene/vinyl acetate-based copolymer, a vinyl acetate/acrylic acid ester-based copolymer, an acrylic copolymer and a polyurethane-based polymer and (B) at least one selected from sodium alginate, sodium carboxymethyl cellulose, a polyvinyl alcohol-based resin and a polyethylene oxide. The lowest film- forming temperature of the component A is <=10 deg.C and the degree of swelling of the dried formed coating film in water at 20 deg.C is preferably 0.1-1.5.</p> |
