Abstract
Provided is an eco-friendly rotogravure hot melt ink composition. More specifically, the present invention provides the rotogravure hot melt ink composition meeting requirements of a carbon footprint system by using, as a vehicle, poly propylene carbonate prepared using carbon dioxide as a raw material. The rotogravure hot melt ink prepared by the composition of the present invention has a higher printing density and more easily performs printing at low temperature than a poly vinyl acetate based hot melt ink according to the related art.
