ABSTRACT:
In a color image-forming medium, a substrate is coated with a color-developing layer which is composed of at least one kind of heat-sensitive color-developing component, and a plurality of pressure-sensitive microcapsules. Each of the pressure-sensitive microcapsules is filled with a dye exhibiting a first single-color, and features a pressure/temperature characteristic to be broken when being subjected to a predetermined pressure within a first temperature range. The heat-sensitive color-developing component features a thermal color-developing characteristic to develop a second single color within a second temperature range defined by a first critical temperature and a second temperature. The first critical temperature is in the first temperature range, and the second critical temperature exceeds an upper limit temperature of the first temperature range.
