Document Type and Number:
WIPO Patent Application WO/2020/039975
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a water-developable flexo printing plate original plate, a flexo printing plate, and a photosensitive resin composition which are capable of maintaining good water-developability and suppressing adhesion and aggregation of a dispersed substance in a water developer, during repeated use of the developer and during disposal of the developer. A water-developable flexo printing plate original plate according to the present invention has a photosensitive layer that contains water-dispersible particles, wherein the water-dispersible particles each have: a core containing a polymer and having a glass transition temperature of 0°C or less; and a shell containing a polymer and having a glass transition temperature of 10°C or more.
