ACTINIC-RADIATION-CURING COMPOSITION, ACTINIC-RADIATION-CURING INK, AND IMAGE FORMATION METHOD AND INKJET RECORDER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an actinic-radiation-curing composition and an actinic-radiation-curing ink each of which is excellent in storage stability and can give a highly sharp recorded image excellent in character quality and free from color bleed under various environments and to provide an image formation method and an inkjet recorder.;SOLUTION: The actinic-radiation-curing composition contains (A) a photo acid generator, (B) an oxetane-ring-containing compound represented by formula (1), and (C) a sensitizer which is at least one member selected from among a polycyclic aromatic compound, a carbazole derivative, and a thioxantone each of which may be substituted with a hydroxyl group or an aralkyloxy or alkoxyl group which may be substituted and has an ultraviolet spectrum absorption at a wavelength longer than 300 nm. In formula (1), R₁ to R₆ are each a hydrogen atom or a substituent, provided that at least one of R₃ to R₆ is a substituent.;COPYRIGHT: (C)2004,JPO
