    • Volatile, hydrolyzable silyl-substituted dyestuffs are used in transfer sheets which, by heating, transfer an image to a substrate. The image has high optical density and resistance to diffusion in high temperature environments. The dyestuffs are of the formula ##STR1## wherein A is a dyestuff nucleus selected from anthraquinone, naphthoquinone, phenylazophenyl or styryl, which nucleus is substituted by R and may be substituted by auxochromic or bathochromic groups, R is H, alkyl of 1 to 6 carbon atoms, phenyl or Q, and at least one R is Q, Q is --R.sup.1 --W--Si(R.sup.2).sub.3, R.sup.1 is a divalent aliphatic group of 2 to 10 carbon atoms, W is 0, S or NR.sup.3, R.sup.3 is H, alkyl of 1 to 6 carbon atoms or phenyl and each R.sup.2 is individually the same or different selected from hydrogen, hydrocarbyl, hydrocarbyloxy, chlorohydrocarbyl or bromohydrocarbyl in which the sum of carbons is not greater than 12.
    • 挥发性,水解性甲硅烷基取代的染料用于转印片材,其通过加热将图像转印到基底上。 该图像在高温环境中具有高光密度和耐扩散性。 所述染料具有式“IMAGE”,其中A是选自蒽醌,萘醌,苯基偶氮苯基或苯乙烯基的染料核,该核被R取代,并且可以被辅色颜料或红色色素基团取代,R是H,1至6的烷基 碳原子,苯基或Q,并且至少一个R是Q,Q是-R1-W-Si(R2)3,R1是2至10个碳原子的二价脂族基团,W是0,S或NR3,R3 是H,1至6个碳原子的烷基或苯基,每个R 2各自独立地选自氢,烃基,烃氧基,氯代烃基或溴代烃基,其中碳的总和不大于12。
