Abstract
A method for determining coat weight of a transparent primer coating for liquid electrophotographic printing processes is described, in which an optical brightening agent is added to an aqueous transparent primer composition in an amount of less than 0.1 wt. % based on the total solids content of the primer composition to produce a test composition, the test composition is applied onto a test substrate to produce a transparent primer coating, the fluorescence of the transparent primer coating is measured, and the coat weight of the transparent primer coating based on the fluorescence of the transparent primer coating is determined.
