Abstract
A full color recording material comprising a support having thereon at least three silver halide photosensitive emulsion layers which contain respectively couplers which form yellow, magenta and cyan colorations and which are sensitive to light of different wavelength regions, at least two of the said layers being spectrally sensitized selectively to match laser light beams of wavelengths of at least 670 nm, wherein the at least two layers aforementioned contain at least one type of crosslinking type spectrally sensitizing dye.
