  • Compositions and thermal mass transfer donor elements for use in producing signage articles
    Patent number: 6190757
    Abstract: Coatable thermal mass transfer precursor compositions, suitable for producing thermal mass transfer donor elements, are described, the coatable compositions comprising a polyalkylene binder precursor; an acrylic binder precursor; an effective amount of a pigment to provide the desired color to a thermal mass transfer composition using the coatable composition; and d) a diluent (preferably water) in which the polyalkylene binder precursor, acrylic binder precursor, and pigment are all dispersed therein. Signage articles produced using the donor elements are also described.
    Type: Grant
