PURPOSE:To improve the adhesion of a compsn. to a substrate, the developability with an aq. alkali developing soln. and printing resistance by blending a prescribed monomer or oligomer with a photopolymn. initiator and specified polyurethane. CONSTITUTION:This compsn. contains a monomer or oligomer having an addition-polymerizable ethylenic unsatd. bond, a photopolymn. initiator and polyurethane contg. phosphonic acid (ester) groups or phosphoric acid (ester) groups. Carboxyl groups are preferably incorporated into the polyurethane and a diazonium compd. is preferably incorporated into this compsn. |
