ACTIVE ENERGY RAY-CURABLE COMPOSITION AND CURED PRODUCT THEREOF

Document Type and Number:

WIPO Patent Application WO/2006/075712

Kind Code:

A1

Abstract:

Disclosed is an active energy ray-curable composition excellent in curability, particularly in deep-section curability which enables to obtain a cured product having excellent heat resistance, weather resistance, oil resistance, compression set and the like. Specifically disclosed is an active energy ray-curable composition characterized by essentially containing the following component (A) and component (B). (A) A vinyl polymer having at least one or more groups represented by the formula (1) below per molecule at a terminal of the molecule, -OC(O)C(R^a)=CH₂ (1). (B) At least one acylphosphine oxide photopolymerization initiator represented by the following general formula (2), R¹R²P(=O)C(=O)R³ (2). Also disclosed is a cured product of such an active energy ray-curable composition.
