N-alkyl-N-para-aminoaryl substituted dicyanovinyl aniline dyes for use in thermal transfer printing |
摘要 |
The present invention provides a dye donor element for use according to thermal dye transfer methods comprising a support having thereon a dye layer comprising a binder and a yellow dye of the class of N-alkyl-N-para-aminoaryl-substituted dicyanovinylaniline dyes. Images obtained with such a donor element in a thermal dye diffusion transfer process are less susceptible to catalytic fading and have thus an improved light fastness.
