LASER RECORDING TYPE HEAT SENSITIVE RECORDING ELEMENT

摘要

A heat sensitive recording element comprising, provided on a support, a heat sensitive recording layer containing at least a light absorbing material for absorbing a laser beam for conversion into heat, an electron donating leuco dye and an electron receiving developer; specifically, a laser recording type heat sensitive recording element which contains, as the electron donating leuco dye, a leuco dye for absorbing a visible−light−region light and a leuco dye having a main laser−absorbing wavelength of at least 600 nm, and which is excellent in laser record adaptability and scanner−readability of a recorded image.
