ETHYLENICALLY UNSATURATED BOND-CONTAINING COMPOUND, PHOTOSENSITIVE COMPOSITION, PHOTOSENSITIVE LITHOGRAPHIC PRINTING PLATE MATERIAL, AND PRINTING METHOD USING THE SAME

Document Type and Number:

WIPO Patent Application WO/2007/072689

Kind Code:

A1

Abstract:

This invention provides a novel ethylenically unsaturated bond-containing compound having satisfactorily high sensitivity also in scanning exposure to a laser beam in an ultraviolet to near infrared wavelength region and having good cured product properties, a photosensitive composition, which has good developability and can form a high-sensitivity and high-strength film, particularly a lithographic printing plate material utilizing properties of good developability and high sensitivity and high strength, especially a lithographic printing plate material, which can eliminate the need to use any developing apparatus, can be mounted on a printing machine without any development treatment to perform printing, and has excellent developability and printing durability on a printing machine, and a printing method. The ethylenically unsaturated bond-containing compound has in its molecule a photooxidizable group and a polymerizable ethylenically unsaturated bond and has a predetermined solubility in water or an aqueous alkali solution. The lithographic printing plate material is characterized by comprising a support and a photosensitive layer provided on the support. The photosensitive layer comprises the ethylenically unsaturated bond-containing compound and, further, a polyhalogen compound as a photopolymerization initiator, a water soluble polymeric binder as a polymeric binder, and an infrared absorber.
