<P>PROBLEM TO BE SOLVED: To provide a cation-curable composition which quickly cures even in the atmosphere, has a good ejection property by an inkjet method, is free from the blur of images, even when the images are formed on glass or metal, and has good adhesiveness, to provide its cured product, and to provide inkjet ink, a hard coating material, and their cured products each comprising the composition. <P>SOLUTION: This cation-curable composition comprises (A) 100 pts.mass of a reactive organic silicon compound represented by the general formula (1): (R<SP>1</SP>)<SB>n</SB>SiX<SB>4-n</SB>[R<SP>1</SP>is a 1 to 20C alkyl; X is a hydrolyzable group; (n) is an integer of 0 to 3] and/or its hydrolyzate, (B) 0.05 to 20 pts.mass of a photo- and/or thermal-cation polymerization initiator, (C) 10 to 500 pts.mass of a cation-polymerizable compound, and (D) water in an amount of 0.05 to 1 mass% based on the total amount of (A) to (C). <P>COPYRIGHT: (C)2007,JPO&INPIT |
