Unitary laminate with permanent indicia pattern: transfer printings onto plastic-coated rigid panels

摘要

A unitary laminate is produced bearing a permanently visible pattern of indicia. The laminate comprises a binder layer, containing pigment, and a transparent layer, each formed of hydrophobic synthetic polymer. Sublimable dyestuff is heat transferred from an auxiliary carrier web to the transparent layer to submerge the pattern into an external surface of the transparent layer.
