PURPOSE:To provide a flexographic printing plate material having excellent water developability, mechanical strength, elasticity, etc., and a flexographic printing plate, etc., which is obtd. therefrom and has excellent printing resistance, etc. CONSTITUTION:The compsn. contains (A) A three-dimensional crosslinked particle polymer which is obtd. by polymerizing at last 1 kinds among any of aliphat. conjugated diene monomers and monofunctional and multifunctional ethylenic unsatd. monomers and have 0.01 to 5mu particle sizes, (B) a hydrophobic elastomer which is incorporated with 30mol% conjugated diene monomer units in at least one molecule of the compsn. and has 5,000 to 1,000,000mol.wt. and <=5 deg.C glass transition temp. of at least one piece, (C) a hydrophilic polymer which contains a hydrophilic functional group in the compsn. and has 1,000 to 1,000,000 mol.wt., (D) a basic nitrogen atom-contg. compd., (E) a photopolymerizable ethylenic unsatd. monomer and (F) a photopolymn. initiator as essential components. |
