Title:
ACTINIC RAY HARDENING INK AND METHOD OF IMAGE FORMING, AND INKJET RECORDING APPARATUS, UTILIZING THE INK
Document Type and Number:
WIPO Patent Application WO/2008/010396
Kind Code:
A1
Abstract:
A photopolymerizable-compound-containing actinic ray hardening ink containing a urethane polymer, characterized in that the number of isocyanate groups remaining in the urethane polymer and urethane oligomers is 0.1% or less of the sum of all isocyanate groups of isocyanate compound needed for the synthesis of the urethane polymer. Accordingly, there is provided an actinic ray hardening ink that despite storage temperature and period, is capable of forming a hardened film excelling in color mixing resistance, hardness, peel resistance and flexibility. Further, there are provided a method of image forming, and inkjet recording apparatus, utilizing the ink.
