Presensitized plate useful for making lithographic printing plate and method for making lithographic printing plate therefrom |
摘要 |
<p>The present invention relates to a presensitized plate useful for making a lithographic printing plate comprising an intermediate layer and a photopolymerizable photosensitive layer on an aluminum substrate in this order, wherein the roughness of a surface of said aluminum substrate (Ra) is in the range of 0.2 to 0.55 mu m and the intermediate layer comprises a polymer compound comprising at least one monomer unit having a sulfonic acid group and a method for making a lithographic printing plate by imagewise exposing the presensitized plate described above and developing the imagewise exposed presensitized plate with a developer comprising an inorganic alkali salt and a nonionic surfactant comprising a polyoxyalkylene ether group. The presensitized plate or the method of the present invention provides a lithographic printing plate showing good contrast between an image area and non-image area, no background contamination during printing, good stability with time and good printing durability.</p> |
