ABSTRACT:
A business record such as a form, tag, label or the like is provided in which different selected colored areas may be activated in a single pass through a printer. In one embodiment, coatings of initially colorless color formers and color developers are coated on selected areas of a substrate surface. The color formers and color developers combine upon exposure to an imaging force, such as heat or pressure, to form different colored visible areas on the sheet. In an alternative embodiment, the coatings of color formers and color developers are self-contained coatings having pressure-rupturable microcapsules containing either the color formers or said color developers.
