This method for producing a layered body includes: a step A for preparing a first layered body by layering a first resin film and a patterned metal layer; a step B for preparing a second resin film having indentations corresponding to the metal layer pattern; and a step C for mating the metal layer pattern and the indentations in the second resin film and bonding together the first layered body and second resin film.

Method for producing layered body, layered body, and multilayered body

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&#xb0; 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&#xb0; C. to 30&#xb0; C.

Photosensitive CTP flexographic printing original plate

The present invention aims to provide a photosensitive CTP flexographic printing original plate wherein no wrinkle is generated during handling of the CTP printing original plate against environmental changes throughout the year and barrier property is also excellent. A water-developable photosensitive CTP flexographic printing original plate which is characterized in that it comprises at least a support, a photosensitive resin layer, a barrier layer and a heat-sensitive mask layer which are sequentially layered, that the barrier layer contains a polyamide resin (A) containing a basic nitrogen atom in a molecule and a polyamide resin (B) containing 40 to 70% by mass of an alkylene glycol structural unit in a molecule, and that a content of the polyamide resin (B) to a total content of the polyamide resin (A) and the polyamide resin (B) is 25 to 52% by mass.
