This invention provides a multicolor record material comprising a plurality of color forming systems each containing a color forming material and a color developing material and adapted to produce different colors individually, the multicolor record material being characterized in that each of the systems contains a substance which absorbs an infrared beam of specified wavelength for causing the system to produce its color but which substantially does not absorb an infrared beam of different wavelength for causing another system to produce the color thereof.
