Title: ACTINIC-RAY-CURABLE COMPOSITION AND CURED OBJECT OBTAINED THEREFROM
Abstract:
An actinic-ray-curable composition having excellent storage stability is provided. The actinic-ray-curable composition comprises an actinic-ray-curable compound (A) having an ethylenically unsaturated double bond, a thiol compound (B) having two or more mercapto groups in the molecule, a reaction inhibitor (C) that inhibits the ethylenically unsaturated double bond from reacting with the mercapto groups, a free-radical polymerization inhibitor (D), and water (E), wherein the content of the water (E) is 0.05 mass ppm or higher but less than 1 mass%. The content of the reaction inhibitor (C) is 0.005-10 parts by mass per 100 parts by mass of the total content of the actinic-ray-curable compound (A) and the thiol compound (B). The content of the free-radical polymerization inhibitor (D) is 0.005-5 parts by mass per 100 parts by mass of the total content of the actinic-ray-curable compound (A) and the thiol compound (B).
