Abstract
Abstract A method of transferring a pigmented image, comprising the steps of: providing a donor element bearing an inkjet printed image containing one or more heat transferable pigments selected from the group consisting ofA. 2-(N-methylcarbamyl)-4-(4-N,N-di-ethylamino-phenylimino)-1,4-naphthoquinone; B. 2-(N-methylcarbamyl)-4-(4-N,N-di-ethylamino-2-methylphenylimino)-1,4-naphthoquinone; C. 1-phenyl-3-N,N-dimethylamino-4-(4-N,N-diethylaminobenzylidene)-pyrazoline-5-one; D. N-ethyl-N-benzyl-3-acetamido-4-(3-methyl-4-cyanoisothiazol-5-ylazo)-aniline; E. N-(2-((2,6-dicyano-4-methylphenyl)azo)-5-(diethylamino)phenyl}methanesulfonamide; F. N-(2-((2,6-dicyano-4-methylphenyl)azo)-5-(dipropylamino)phenyl}methanesulfonamide; and contacting the donor element with an image receiving element; and transferring the heat transferable image to the image receiving element by applying heat to the donor element.
