CATIONICALLY CURABLE COMPOSITION AND CURED PRODUCT THEREOF

摘要

Disclosed is a cationically curable composition with low viscosity which can be quickly photocured even in the atmosphere while having good adhesion to bases such as glasses and resins, excellent glass cleaner resistance and excellent water resistance. Also disclosed are an inkjet ink, a gravure ink and a hard coating material each composed of such a curable composition, and cured products of them. Specifically disclosed is a cationically curable composition composed of (A) 1-100 parts by weight of a phenol derivative having three or more aromatic rings in a molecule wherein the hydrogen atom in some or all of the phenolic hydroxyl groups of the aromatic rings is substituted by a polymerizable functional group, (B) 1-500 parts by weight of a cationically polymerizable compound, and (C) 0.05-20 parts by weight of a photocationic initiator or thermal cationic initiator.
