Abstract (en)
[origin: EP0580120A1] When the counter ion of hydrophilic cationic dyes is substituted with an organic anion including a sulfosuccinate anion such as diethylhexylsulfonate anion, an alkylbenzenesulfonate anion such as a dodecylbenzenesulfonate, an alkylsulfate anion such as a laurylsulfate anion, or a soap anion such as a laurylsulfate anion, the cationic dyes are imparted with hydrophobicity. An ink layer 3 containing the hydrophobic cationic dye is formed on a support 2 to provide a thermal transfer ink ribbon 10. <IMAGE>
