摘要:
A heat-sensitive recording material comprising on a support a heat-sensitive layer comprising color-forming component A, color-forming component B which forms a color by reacting with the color-forming component A, and a tricarbocyanine dye having at least two acidic groups, wherein the tricarbocyanine dye has an absorption maximum wavelength of 650 to 1300 nm in the heat-sensitive layer and has an absorption maximum wavelength 50 nm or more longer than that of an aqueous solution of the tricarbocyanine dye.

摘要:
A method for forming an image is described which includes bringing a transparent heat-sensitive recording material including a transparent support made of a synthetic polymer having thereon a transparent heat-sensitive recording layer into contact with a light-absorbing material, at least at the time of effecting recording, and irradiating the light-absorbing material with a laser beam to heat the transparent heat-sensitive recording layer and to cause color formation therein. High speed, high density, and high quality recording can be performed with an increased light absorption efficiency.
