Abstract

An object of the present invention is to provide a laminate for forming an image with high sensitivity of the heat-sensitive image forming layer and excellent manufacturing suitability, and a manufacturing method of a flexographic printing plate using the same. The laminate for forming an image is a laminate for forming an image, which is for forming a mask used for manufacturing a flexographic printing plate, including, in the following order, a carrier sheet, a barrier layer, and a heat-sensitive image forming layer, in which the barrier layer contains a first infrared absorbing dye, the heat-sensitive image forming layer contains an ultraviolet absorber and a second infrared absorbing dye, both of the first infrared absorbing dye and the second infrared absorbing dye are a compound having an absorption at a wavelength of 1070 nm and having a mass absorption coefficient at the wavelength of 1070 nm of 50 L/(g·cm) or more, and both of the barrier layer and the heat-sensitive image forming layer contain a third infrared absorbing dye having an absorption at a wavelength of 830 nm.
