    Abstract: Corresponding images (an image and a mirror image thereof) are provided on adjacent surfaces of two sheets. An encapsulated liquid reactant precursor is supported on one of the surfaces and a co-reactant is coated on the other surface. The adhesion/cohesion characteristics of the co-reactant coating are so adjusted and selected that upon pressure-effected rupture of the particular capsules used, some of the co-reactant (as well as some precursor) physically transfer and the balance of each remains in situ and does not transfer. Substantially identical chemical reactions are thus produced concurrently on both adjacent surfaces to provide corresponding colored images thereon.
