Abstract:
1. A multi-layer sheet material, which comprises: (a) a base substrate; (b) optionally, one or more undercoat layers; (c) one or more thermal layers; (d) one or more thermal overcoat layers; and (e) one or more layers receptive to inks used in digital offset printing presses, wherein the multi-layer sheet material is imageable by both direct thermal printing devices and digital offset printing presses, wherein the one or more thermal overcoat layers is prepared from an aqueous coating formulation comprising: a blend of modified polyvinyl alcohol and urethane resins and/or urethane/acrylic copolymers; inorganic pigments; from about 0.2 to about 5% by dry weight, based on the total dry weight of the coating formulation, of one or more crosslinking agents, defoaming agents and surfactants; from about 2 to about 14% by dry weight, based on the total dry weight of the coating formulation, of one or more lubricants and waxes, wherein the ratio of resin to pigment ranges from about 5:1 to about 1:3.
