Abstract
In an optical recording medium, a light absorbent can be incorporated into a color-developing layer without separately constituting a light absorbing layer by holding the light absorbent in a dispersed or dissolved state in a solvent soluble or heat fusible material. Thus, an optical recording medium which exhibits satisfactory image density with a small amount of the light absorbent can be provided.
