<p>In a thermal transfer print, the ready diffusion of dyes through the receiver layer, which is necessary for effecting their thermal transfer from a dyesheet during printing, can also lead to subsequent diffusion within the print, with consequent degradation of print quality. This form of print instability is now countered by using a receiver layer comprising a dye-receptive polymer composition doped with a print stabiliser consisting of a toluene sulphonamideformaldehyde condensation product.</p>
