Title:
INK COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2011/125538
Kind Code:
A1
Abstract:
Provided is an ink composition comprising a polymerizable compound having two or more carboxylic acid ester groups and two or more vinyl ether groups per molecule, an SP value of between 9.0 and 11.5, and a logP of between 1.5 and 6.5. The polymerizable compound simultaneously prevents hydrolysis of the vinyl ether under the effects of the humidity in the air when inkjet printing is performed in a high-humidity environment and has good photoacid generator solubility. By using the polymerizable compound, it is possible to provide a polymerizable compound and an active energy beam-curable inkjet ink having excellent adherence, weather resistance, safety, odor resistance during printing, and odor resistance of the printed product.
