摘要： A thermal transfer inked ribbon having good transfer property and offering vivid and highly durable transfer image. In constituting a thermal transfer inked ribbon (1) by using a hot-melt resin binder material as a main component and by forming an ink layer (13), low-lubrication fine particles are contained in the ink layer (13), the low-lubrication fine particles without being softened at a temperature at which the binder material softens. Since the hot-melt resin is used, the transfer image features enhanced durability. Besides, since fine particles are contained, the thermal transfer inked ribbon can be favorably cut. The fine particles have low lubrication and suppress slippage. The low-lubrication fine particles have an average particle diameter of 0.3-3.0 mu m, and are made of benzoguanamine-formaldehyde condensate resin, melamine-formaldehyde condensate resin, benzoguanamine-melamine-formaldehyde condensate resin, or polytetrafluoroethylene resin. The ink layer (13) contains 10-60 wt.% or preferably 20-50 wt.% such resin.
