A carboxyl group-containing resin, a photopolymerizable compound, a photopolymerization initiator containing a bisacylphosphine oxide-based photopolymerization initiator and an? -Hydroxyalkylphenone-based photopolymerization initiator, and a fluorescent dye. Wherein the bisacylphosphine oxide-based photopolymerization initiator contains bis- (2,4,6-trimethylbenzoyl) -phenylphosphine oxide. Hydroxy-2-methyl-1-phenyl-propan-1-one. The mass ratio of the bis- (2,4,6-trimethylbenzoyl) -phenylphosphine oxide and the 2-hydroxy-2-methyl-1-phenyl-propan-1-one is 2: 1 to 1:10 . |
