Abstract
An article comprising a substrate such as cellulose casing, having thereon a desired indicia such as grill marks or a corporate logo. The indicia comprises an aluminum-organic dye lake and a binder-carrier, with the lake dispersed in the binder-carrier and bonded to the substrate by the binder-carrier in a moisture insensitive manner to form the indicia. The organic dye may for example be an FD&C color and the binder-carrier may for example be zein or shellac. The indicia is substantially completely transferable from the substrate to a contiguous edible surface in the presence of water. The food surface may for example be frankfurter and the transfer may for example take place during elevated temperature processing of the frankfurter emulsion in the cellulose casing.
