- 37 - ABSTRACT OF THE DISCLOSURE The present invention imparts elasticity, reproducibility of dots, film toughness and wear resistance to printing plates obtained therefrom, in addition to the good water developability and mechanical properties. The present invention thus provides a photosensitive resin composition comprising; (A) 10 to 90 % by weight of specific crosslinked polymer particles having a particle size of 0.01 to 5 micron, (B) 10 to 70 % by weight of a specific hydrophobic elastomer, (C) 1 to 25 % by weight of a hydophilic polymer having a molecular weight of 1,000 to 1,000,000, (D) 1 to 30 % by weight of a basic nitrogen- containing compound, (E) 1 to 60 % by weight of a photopolymerizable ethylenically unsaturated monomer, and (F) 0.01 to 10 % by weight of a photopolymerization initiator; % by weight being based on a total amount of the resin composition. The present invention also provides a flexoprinting plate obtained from the above resin composition and a process for producing the flexoprinting plate.
