<P>PROBLEM TO BE SOLVED: To provide a laser-engravable printing original plate can produce a forme excellent in resolution without causing defective printing. Ž<P>SOLUTION: A printing original plate in which a photosensitive resin layer is set on a support is irradiated with light, crosslinked, and cured to obtain the printing original plate for laser carving. In the flexographic printing original plate, the photosensitive resin layer contains water dispersion latex having a butadiene skeleton or an isoprene skeleton in a molecular chain (A), a hydrophilic photopolymerizable monomer (B), rubber (C), and a photopolymerization initiator (D).
