Abstract
A reusable, heat transfer recording ink sheet using an ink containing, in addition to a colorant and a vehicle, ethylene/vinyl acetate-coated fine powders capable of being partially transferred to an inkreceiving recording medium for each transfer recording, the ethylene/vinyl acetate having a number average molecular weight of 30,000 or less and a vinyl acetate unit thereof being in the range of 18 to 45% by weight of the copolymer. The ink sheet ensures that prints having a sufficiently high density of print and an excellent fixing of the ink to the recording medium are obtained, together with a remarkably increased number of the repetitions of use of the sheet.
