Abstract: A set of manifold business forms includes at least three plies having selected mating surfaces thereof coated with chemicals which are capable of reacting with one another to produce a colored mark. An intermediate ply of the set is of tissue material having its back surface coated with a color precursor in the form of a microencapsulated liquid, and the bottom ply of the set is of an opaque material having its front surface coated with a composition of a generally solid record-developing material. The top ply of the set is likewise of an opaque material so that, upon the application of pressure to the set, an image thereof is developed on the top surface of the bottom ply. The use of a coated-back tissue avoids capsular damage during the printing operation of the forms since all that is printed is a coated front sheet.
