<P>PROBLEM TO BE SOLVED: To provide a photopolymerizable composition for laser, the composition having a photosensitive layer containing at least (A) an organic boric acid salt and (B) a sensitizing dye, and to provide a planographic printing plate having a layer of the above photopolymerizable composition on a support, wherein the photopolymerizable composition for laser is formed and the planographic printing plate for laser have excellent image strength. <P>SOLUTION: The photopolymerizable composition for laser includes a photosensitive layer containing at least (A) an organic boric acid salt and (B) a sensitizing dye, and the planographic printing plate for laser has a layer of the above photopolymerizable composition on a support; wherein the add amount of the sensitizing dye is controlled to shift a maximum absorption wavelength to a shorter wavelength by 8 nm or more. <P>COPYRIGHT: (C)2007,JPO&INPIT |
