Title: Method for coating a plurality of fluid layers onto a substrate

Abstract: A method for reducing coating defects caused by strikethrough when simultaneously slide coating a first fluid layer, a second fluid layer, and a third fluid layer. The method includes preparing the first, second, and third fluids such that the first solute is incompatible with the second and third solutes and such that the first fluid minimizes strikethrough of at least one of the second and third fluids to a slide surface when the first fluid is positioned between the slide surface and the second and third fluids. The present invention is useful in preparing imaging, data storage, and other media.
