There is provided a lithographic printing plate precursor that enables image recording using a laser and that provides an excellent scumming resistance and an excellent developability while maintaining a satisfactory printing durability. Also provided are a platemaking method, and a novel polymerizable monomer. A lithographic printing plate precursor has a support, and an image recording layer disposed thereon and containing a radical polymerization initiator and a polymerizable monomer that has a sulfonamide group and at least two ethylenically unsaturated groups; a lithographic printing plate platemaking method uses this lithographic printing plate precursor; and a polymerizable monomer has a sulfonamide group and at least two ethylenically unsaturated groups.
本发明提供了一种平版印刷版原版,可使用激光进行图像记录,并具有优异的抗浮渣性和显影性,同时还能保持令人满意的印刷耐久性。此外,还提供了一种制版方法和一种新型可聚合单体。一种平版印刷制版前体具有一个支撑体和一个图像记录层,图像记录层放置在支撑体和图像记录层上,图像记录层含有一个自由基聚合引发剂和一个可聚合单体,可聚合单体具有一个磺酰胺基团和至少两个乙烯不饱和基团;一种平版印刷制版方法使用这种平版印刷制版前体;一种可聚合单体具有一个磺酰胺基团和至少两个乙烯不饱和基团。
