摘要：
Disclosed are diazahemicyanine hydrophobic cationic dyes represented by the formula (1): ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are lower alkyl groups having not more than 5 carbon atoms, R.sup.5 is a lower alkyl group having not more than 5 carbon atoms or a lower alkoxy lower alkyl group having not more than 6 carbon atoms, and Z.sup.- is a counter ion having a hydrophobic organic group, and a thermal transfer ink ribbon having a substrate and and ink layer laminated thereon containing said cationic dye.
