Abstract
The present invention aims to provide a CTP flexographic printing original plate having such high performances that, even under a severe low-temperature condition of 10° C. or lower, no crack is generated in a heat-sensitive mask layer and further that, even when the heat-sensitive mask layer is formed as a thin film, no unevenness is generated in an optical density in transmission. A photosensitive CTP flexographic printing original plate, characterized in that, it comprise at least a support, a photosensitive resin layer and a heat-sensitive mask layer which are sequentially layered, that the heat-sensitive mask layer contains a methoxymethylated polys side resin (A) and a water-soluble polyamide resin (B) containing a basic nitrogen atom in a molecule, and that a glass transition point of the polyimide resin (A) is 0° C. to 30° C.
