Abstract
The invention provides a novel micro-capsule toner, having a constitution and features absolutely differing the conventional counterpart, that has fully solved the conventional problem that the pattern may vanish. The toner is a novel thermal micro-capsule toner in which the micro-capsule is composed of two or more types of compositions, and in which a component that will be thermally decomposed to generate a gas has been added to the cell or core of the micro-capsule of the compositions, or to the interface between the cell and the core. The toner is added to a paint or an adhesive, or applied onto a carrier, or added to a moldable resin. By directly or indirectly heating, the toner allows a nonvolatile pattern to be developed. The micro-capsule will rupture by simple heating so that a nonvolatile patter is obtained. It becomes possible to print characters and images on various materials such as paper, synthetic resins, woods, and metals.
