Title:
PHOTOCURABLE COMPOSITION SUITABLE FOR NEAR-INFRARED LED LIGHT SOURCE IRRADIATION AND CURING AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/208970
Kind Code:
A1
Abstract:
A photocurable composition suitable for NIR-LED light source curing, containing a polymethylene cyanine compound shown in formula (1) and serving as component I and an oxime ester compound selected from formulas (2-1) and (2-2) and serving as component II. After compounding the component I and the component II, a polymerization reaction of ethylenically unsaturated compounds can be initiated under an NIR-LED light source, good initiating activity is comprised, and the storage stability of the photocurable composition can further be improved. Also disclosed are a method for preparing a photocuring material by irradiating the photocurable composition by using an NIR-LED light source having an emission wavelength of 700-1100 nm, and a cured material obtained by curing the photocurable composition by means of the NIR-LED light source.
