Title:
PHOTOSENSITIVE CTP FLEXOGRAPHIC PRINTING PLATE
Document Type and Number:
WIPO Patent Application WO/2018/179674
Kind Code:
A1
Abstract:
Provided is a CTP flexographic printing plate which exhibits high performance and uniform transmission and optical density even when a heat-sensitive mask layer is formed as a thin film, and which does not exhibit cracking in the heat-sensitive mask layer under harsh cold conditions of 10°C or below. The provided photosensitive CTP flexographic printing plate is a photosensitive printing plate obtained by sequentially layering at least a support body, a photosensitive resin layer, and a heat-sensitive mask layer, and is characterized in that the heat-sensitive mask layer contains a methoxymethylated polyamide resin (A) and a water-soluble polyamide resin (B) containing a basic nitrogen atom in each molecule thereof, and the glass transition temperature of the polyamide resin (A) is 0-30°C.
