Abstract: There is provided a method for producing a pattern, and the method includes forming a film by removing the solvent from a photosensitive resin composition containing (Component A) a polymer including a monomer unit (a1) having a residue of a carboxyl group or a phenolic hydroxyl group protected with an acid-decomposable group, and a monomer unit (a2) having an epoxy group and/or an oxetanyl group; (Component B) a photo acid generator; and (Component C) a solvent; exposing the film patternwise to an active radiation; developing the exposed film with an aqueous developer liquid to form a pattern; and baking the pattern by heating.

Abstract: 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.

Abstract: A lithographic printing plate precursor includes a support, and an image-recording layer, the image-recording layer contains a urethane resin having a polyalkylene oxide chain represented by the formula (1) as defined herein in a side chain, an infrared absorbing agent, a radical polymerizable compound and a radical polymerization initiator, and an unexposed area of the image-recording layer is capable of being removed with at least one of dampening water and ink.
