摘要
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 IMAGE 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 -R1-W-Si(R2)3, R1 is a divalent aliphatic group of 2 to 10 carbon atoms, W is 0, S or NR3, R3 is H, alkyl of 1 to 6 carbon atoms or phenyl and each R2 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.
