Abstract
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.

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.
A method for making an image using a thermal imaging system consisting of a dye donor element 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 and an image receiving element having on a support an image receiving layer, said method comprising the steps of:
- bringing the dye layer of said donor element in face-to-face relationship with the receiving layer of said receiving element,
- image-wise heating a thus obtained assemblage and
- separating said donor element from said receiving element.
