Heat-sensitive recording material for laser recording

A heat-sensitive recording material for laser recording comprising a support having thereon a heat-sensitive layer comprising at least a first substantially colorless coloring component, a second substantially colorless coloring component which reacts with said first substantially colorless coloring component to develop a color, and an infrared-absorbing dye,

• wherein said first substantially colorless coloring component is present in microcapsules and said infrared-absorbing dye and said second substantially colorless coloring component are present outside microcapsules,
• wherein said first substantially colorless coloring component is a photodecomposable diazo compound and said second substantially colorless coloring component is a coupler, or said first substantially colorless coloring component is an electron-donating dye precursor and said second substantially colorless coloring component is a developer, and
• wherein the heat-sensitive layer is formed by coating a coating solution containing an emulsion obtained by dissolving said second substantially colorless coloring component and said infrared-absorbing dye in an organic solvent, which is slightly soluble or insoluble in water, and then emulsion-dispersing the solution in an aqueous medium.
