PHOTOREACTIVE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2020/085413
Kind Code:
A1
Abstract:
Provided is a photoreactive composition in which even inner portions can be efficiently cured. The photoreactive composition comprises a compound having a radical-polymerizable functional group, a photosensitizer, and a thermoradical generator. When the photoreactive composition is introduced into a glass tube having an outer diameter of 4.932-4.970 mm, a wall thickness of 0.38 mm, and a length of 17.78 cm and constituted of borosilicate glass, to fill up a 15-cm-length portion of the glass tube, a portion of the introduced photoreactive composition located at a distance of 1 cm from the upper end thereof is irradiated for 60 seconds with light at a light intensity of 2,000 mW/cm2 using an LED lamp having a center wavelength of 365 nm, and the photoreactive composition is allowed to stand still at 25°C for 1 hour, then the conversion of the photoreactive composition as determined at a position 10 cm below the upper end thereof is 20% or higher.
