Abstract
Abstract The invention relates to aqueous low-viscosity printing inks which, in addition to containing at least one sublimable dye suitable for transfer printing and optionally further ingredients, also contains a mixture of at least one polyvinyl alcohol and a polyacrylate and/or a styrene acrylic copolymer. Such printing inks are suitable in particular for printing supports for transfer printing on gravure printing machines.
