Abstract: An image-forming substrate has a sheet of paper, and a layer of microcapsules coated over the paper sheet. The microcapsule layer contains at least one type of microcapsules filled with a liquid dye, and a shell wall of each of the microcapsules is composed of resin that exhibits a temperature/pressure characteristic such that, when each of the microcapsules is squashed under a predetermined pressure at a predetermined temperature, the liquid dye seeps from the squashed microcapsule.

Abstract: A pressure-sensitive and heat-sensitive recording apparatus has a pre-coating container that pre-coats a recording sheet prior to a printing operation on the recording sheet. The pre-coating material container, ribbon cassette and an over-coating material container are provided in a recording head, while being movable in a printing direction lead by the pre-coating material container. The printed color-image is protected by an over-coating material dispensed from the trailing over-coating material container.

Abstract: In an image-forming system, an image-forming substrate is used that includes a paper sheet, and a microcapsule layer, coated over the paper sheet, which contains at least one type of microcapsule filled with a dye. Each microcapsule exhibits a characteristic such that, when a microcapsule is compacted under a given pressure at a given temperature, the dye seeps from the compacted microcapsule. A pressure/temperature applicator includes a roller platen, a thermal head having at least one arcuate bimetal element associated with the platen such that the substrate can be interposed between the platen and the thermal head, and an electrical energization system that electrically heats the arcuate bimetal element in accordance with image-information data.
