Abstract
An in-line method for making a water-activatable laminate. The method includes providing a polymeric film having a first surface and a second surface. An opaque water activatable material containing from about 5 to about 40 wt. % pigment and from about 60 to about 95 wt. % binder is applied to the first surface of the film using an in-line coating technique selected from a flexographic coater, a rotary screen press, and a rotogravure coating technique. The coating is then dried to provide a single water activatable opaque layer having a thickness ranging from about 0.60 mil to about 2.0 mil. The binder for the opaque coating layer includes a mixture of solvent, butyl acetate, ethylene glycol monobutyl ether and propylene glycol. The laminate may be used multiple times without adversely affecting its ability to reveal and hide images.
