Abstract
A method includes contact printing an active composition onto a surface of a release substrate to form a printed surface. The active composition spontaneously dewets the surface of the release substrate to form active deposits on the surface of the release substrate. The active composition comprises an active agent dissolved or dispersed in an aqueous liquid vehicle. A pressure-sensitive adhesive layer is disposed on the printed surface.
