Dye-donor element comprising tricyanovinylaniline dyes

摘要

Dye-donor element for use according to thermal dye transfer methods, said element comprising a dye layer comprising at least one dicyanovinylaniline dye, wherein the amino group of the aniline function of said dye carries an aryl group not being substituted with a dicyanovinyl group and a hydrocarbon or substituted hydrocarbon group linked by a secondary carbon atom to said amino group. The dyes have very good light-fastness and good spectral absorption characteristics.
