摘要:
A magenta anthraquinone dyestuff for sublimation thermaltransfer printing is here disclosed. In general, the anthraquinone dyestuff has a strong yellow tone, but in the anthraquinone in which the position of No. 2 is substituted by a phenoxy group, absorption is made on the side of a longer wave length. This kind of dyestuff is characterized by solubility in a solvent, sublimation, adhesion, fastness and the like. The general formula is: A preferred example has R = 3-Me; R = H; R = NH2.
