ABSTRACT:
A pressure-sensitive transfer recording medium adapted to overlapping strike printing on a low-noise impact printer, comprising a foundation, and a porous ink-releasing layer containing an ink paste provided on the foundation, the ink paste comprising a coloring agent, a liquid vehicle and a starch substance, the liquid vehicle comprising as a main component at least one member selected from the group consisting of a glycerol higher fatty acid ester, a polyglycerol higher fatty acid ester and a sorbitan higher fatty acid ester, the ink paste having a viscosity of 4.times.10.sup.3 to 12.times.10.sup.3 cp at 25.degree. C. The recording medium ensures images of a high density for an initial strike and an excellent printing durability, thereby giving clear images without blot or unevenness for a multiplicity of overlapping strikes at the same portion of the recording medium, in printing on a low-noise impact printer under low-temperature circumstances as well as under ordinary-temperature circumstances.
