Abstract

The subject-matter of this Specification is substantially the same as that of the parent Specification but the claims are concerned with a pressure-activatable self-generating-image-forming sheet material including normally separated, image-forming coreactants which form visible images on contact with one another comprising a unified web carrying as a filler therein minute, hollow, rupturable capsules that are insoluble but dispersible in water, have shells of an aldehyde condensation polymer and contain one of the coreactants in a water-immiscible liquid fill, the second colour reactant being carried by the sheet material adjacent to the capsules, whereby to produce the distinctive colour in the web upon rupture of the capsules.
