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 R¹ = 3-Me; R³ = H; R⁴ = NH₂.
本文公开了一种用于升华热转印印刷的品红色蒽醌染料。一般来说,蒽醌染料具有较强的黄色调,但在 2 号位置被苯氧基取代的蒽醌中,吸收波长较长。这种染料的特点是在溶剂中的溶解性、升华性、附着性、牢度等。其通式为
一个优选的例子是 R¹ = 3-Me;R³ = H;R⁴ = NH₂。
