Abstract
The present invention comprises an abrasion-resistant and blocking-resistant hot melt ink, which can be printed at a temperature of approximately 80.degree. C. to 100.degree. C. which includes an adhesion-facilitating substance, a viscosity-facilitating substance and a copolymer of polyvinyl pyrrolidone with one or several long-chain .alpha.-olefins with at least 10 carbon atoms. The ink has excellent adhesion properties with respect to the imprintable material or printing substrate, and withstands normal handling such as folding or bending. Additionally, the present invention includes colored hot melt inks that exhibit improved transparency properties even if the inks are formulated for printing at low temperatures.
