Abstract

PURPOSE: To enhance the preservability of an image, by forming a color forming system from a usual colorless or light-colored dye precursor and an aromatic isocyanate compound.
CONSTITUTION: A color forming system consisting of a usual colorless or light- colored dye precursor and an aromatic isocyanate compound is formed on the same base material or said components are applied to different base materials. When the dye precursor is brought into contact with the aromatic isocyanate compound through external energy, for example, heat, both components are reacted to form a colored reaction product. Since this reaction is irreversible, the reaction product once reacted does not return to the colorless or light-colored dye precursor. As a result, the image composed of the obtained reaction product is excellent in image preservability such as light fastness, plasticizer resistance or the like. As the dye precursor, compounds of a triphenylmethane type, a fluorane type, a diphenylmethane type, a thiazine type, a spiropirane type or the like are designated.
