<p>A highly sensitive thermal transfer printing ink sheet is provided giving very little low temperature thermal transfer and irregularity of picture, even when printed in high temperature and high humidity conditions, and has an excellent long term storage stability, by using as dye-binder polycarbonate resin selected from: (a) a polycarbonate resin of which the diol component is at least one bis(hydroxyaryl) cycloalkane, (b) a polycarbonate resin of which the diol component is a mixture of bis(hydroxyaryl) cycloalkane and at least one compound of formula I below, or (c) a mixture of polycarbonate resins of (a) or (b), or a mixed polycarbonate resin of (a) and (b), and a polycarbonate resin of which the diol component is at least one compound of formula I below, HO - PHI - A - PHI - OH I wherein PHI represents an aryl group and A is O, S or -CR1R2-, where R1 and R2 are each independently a hydrogen atom or alkyl group.</p> |
