ABSTRACT:
Disclosed is a thermo-sensitive transfer ink ribbon to be used for producing a dry type transfer material, which is constituted by: a ribbon substrate material; an ink layer formed on a surface of the substrate material and containing a coloring agent, a binder agent, a pressure-sensitive adhesive in the form of dispersion of fine particles; and a transfer property control layer formed on the ink layer and containing a thermo-sensitive adhesive and a tackiness agent. Further disclosed is a method of producing the thermo-sensitive transfer ink ribbon which comprises the steps of: dissolving/dispersing a coloring agent, a binder agent, and a pressure-sensitive adhesive in a predetermined solvent; applying the solvent onto a surface of a ribbon substrate material so as to form an ink layer on the surface; and coating the ink layer with a mixture in which a thermo-sensitive adhesive and a tackiness agent are mixed with each other in the form of a predetermined solution or dispersion liquid.
