Title:
IMAGE FORMATION LAMINATE AND METHOD FOR MANUFACTURING FLEXOGRAPHIC PRINTING PLATE
Document Type and Number:
WIPO Patent Application WO/2022/138713
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an image formation laminate that has high sensitivity in a thermosensitive image forming layer and has excellent manufacturing suitability and a method for manufacturing a flexographic printing plate using the same. The image formation laminate of the present invention is an image formation laminate (10) for forming a mask used to manufacture a flexographic printing plate. The image formation laminate (10) has a carrier sheet (6), a barrier layer (3), and a thermosensitive image forming layer (4) in this order. The barrier layer contains a first infrared absorbing dye. The thermosensitive image forming layer contains an ultraviolet absorbing agent and a second infrared absorbing dye. Both the first infrared absorbing dye and the second infrared absorbing dye are compounds that have absorption at a wavelength of 1070 nm and have a mass absorption coefficient of 50 L/(g･cm) or more at a wavelength of 1070 nm. Both the barrier layer and the thermosensitive image forming layer contain a third infrared absorbing dye having absorption at a wavelength of 830 nm.
