(57) [Summary]nPROBLEM TO BE SOLVED: To have excellent spectral characteristics, light, heat, air, chemicals. Azo dyes, inkjets with high robustness against An ink and a thermal transfer dye donating material are provided.nAn azo dye represented by the following general formula (I): Ink jet ink and thermal transfer using the dye Provide recording material.nEmbedded imagen In the formula, Z is necessary to form a 5- to 7-membered ring together with the N atom Atomic group. R 1 Is a hydrogen atom, an oxy radical group, Aliphatic group, aliphatic oxy group, acyl group, aliphatic oxyca Rubonyl group, aryloxycarbonyl group, acyloxy Represents a group. R Two , R Three , R Four And R Five Is an alkyl group And R Two And R Three , R Four And R Five Each form a ring Good. Dye shows the dye groups required to form the azo dye. You. |
