Abstract
A method for preparing a flexible article comprising a substrate such as cellulose casing having thereon a desired indicia such as grill marks or a corporate logo, which in turn comprises a water soluble underlayer such as caramel and a water insoluble binder-sealant layer such as shellac. The binder-sealant covered colorant indicia is substantially completely transferable from the substrate to a contiguous edible surface such as a frankfurter, in the presence of moisture.
Claims27
A method for preparing an a flexible article comprising a substrate and an indicia thereon comprising the steps of:
- a) providing a plasticized substrate:
- b) applying from an aqueous solution, as a portion of a desired indicia to the substrate, a water soluble colorant layer in contiguous and nondiffusible association with said substrate;
- c) drying at least the applied colorant indicia portion;
- d) applying as another portion of said indicia a binder-sealant and organic solvent mixture coating over and entirely enclosing the dry colorant layer top surface with the coating perimeter outwardly extending beyond the colorant layer extremities so as to directly contact the substrate, said binder-sealant having a melting point above about 100.degree. F. and being water insoluble;
- and
- e) evaporating said organic solvent from said coating so as to form a dry binder-sealant coating entirely enclosing the dry colorant layer top surface being adhered thereto the surrounding substrate;
- the binder-sealant covered colorant indicia being substantially completely transferable from said substrate to a contiguous edible surface in the presence of moisture.
