摘要：A thermal dye transfer sheet having a dye layer provided on at least one side ofa substrate, which is used for thermal dye transfer recording system carrying outrecording by transferring a dye or dyes in the dye layer to a dye-receiving material byheating means, wherein the dye layer contains a pyrazolonemethine type dye of thefollowing formula: wherein R<1> and R<2> can be respectively independently selectedand are a lower alkyl group which may be substituted, a lower alkenyl group which maybe substituted or an aryl group which may be substituted; and R<3> and R<4> can berespectively independently selected and are a lower alkyl group which may besubstituted, a dialkylamino group, a -COOR<5> group or a -CONR<6>R<7> group, inwhich R<5> is a lower alkyl group which may be substituted, a lower alkenyl group whichmay be substituted or an aryl group which may be substituted and R<6> and R<7> canbe respectively independently selected and are a hydrogen atom, a lower alkyl groupwhich may be substituted, a lower alkenyl group which may be substituted or an arylgroup which may be substituted.
