Title:
PHOTOSENSITIVE RESIN COMPOSITION, FLEXOGRAPHIC PRINTING ORIGINAL PLATE, AND METHOD FOR PRODUCING FLEXOGRAPHIC PRINTING PLATE
Document Type and Number:
WIPO Patent Application WO/2023/223919
Kind Code:
A1
Abstract:
This disclosure provides a flexographic printing plate having at least: a region (A1) in which a support body and a relief layer are sequentially stacked, and the storage elastic modulus at a frequency of 2,000 Hz is 100 MPa to 500 MPa, inclusive, during dynamic viscoelasticity mapping measurement through AFM of a cross section attained by cutting 1 μm from the surface layer of the surface of the relief layer opposite to that in contact with the support body; and a region (B1) in which the storage elastic modulus at a frequency of 2,000 Hz is 3 MPa to 15 MPa, inclusive.
