Abstract (en)
A donor ribbon construction suitable for thermal mass transfer imaging comprises a fluorescent colorant donor layer over-coated or alternated with an opaque white donor layer. Alternative constructions are disclosed in which donor layers containing fluorescent colorant or opaque white background pigments are interspersed alternated, or over-coated on a substrate. A process for transferring a fluorescent colorant image is also disclosed.
