Title:
FLUORINE-CONTAINING ACTIVE ENERGY RAY-CURABLE COMPOSITION, CURED PRODUCT, AND ARTICLE
Document Type and Number:
WIPO Patent Application WO/2023/112714
Kind Code:
A1
Abstract:
The present invention provides a fluorine-containing active energy ray-curable composition containing specific amounts of (A) a fluoropolyether group-containing acrylic compound represented by the following formula: V1-Rf1-Z-Y(X)b (Rf1 is a divalent perfluoropolyether group. Z is a divalent organic group. Y is a (b + 1)-valent organic group. X is an (α-substituted) acrylic group-containing monovalent organic group. V1 is H, F, or -Z-Y(X)b. b is 1-10.), (B) an acrylic compound having a viscosity of 5,000 mPa·s or less at 23°C and having an (α-substituted) acrylic group in one molecule thereof, and (C) a photopolymerization initiator, wherein the viscosity at 23°C is 10-100,000 mPa·s, and the refractive index at a temperature of 25°C and a wavelength of 589 nm is 1.390 or less. The fluorine-containing active energy ray-curable composition is capable of being cured by means of active energy rays, such as ultraviolet rays or electron beams, is capable of forming a transparent cured product having a low refractive index and excellent water vapor resistance, and is also capable of having excellent handling properties.
