Title:
PHOTOCURABLE COMPOSITION COMPRISING INFRARED-ABSORBING PHOTOSENSITIZER, INITIATOR, ALKENYL ETHER AND/OR OXETANE-BASED COMPOUND
Document Type and Number:
WIPO Patent Application WO/2022/057859
Kind Code:
A1
Abstract:
The present disclosure provides a photocurable composition comprising the following components: (a) at least one infrared-absorbing photosensitizer capable of providing electrons and generating heat energy under irradiation of a 700-2000 nm light source, (b) at least one initiator capable of generating a Bronsted super acid and a radical in the presence of the infrared-absorbing photosensitizer, and (c) an alkenyl ether-based compound and/or an oxetane-based compound. Preferably, the infrared-absorbing photosensitizer is a polymethine cyanine compound, and/or the initiator is an iodonium salt. The present disclosure further provides a method for preparing the photocurable material and a method for interpenetrating a polymer network structure. Finally, the present disclosure further provides a curable material obtainable from the photocurable composition of the present invention.
