Title:
FLUORENE PHOTOINITIATOR, PREPARATION METHOD THEREFOR, PHOTOCURABLE COMPOSITION HAVING SAME, AND USE OF SAME IN PHOTOCURING FIELD
Document Type and Number:
WIPO Patent Application WO/2018/049976
Kind Code:
A1
Abstract:
Provided are a fluorene photoinitiator, a preparation method therefor, a photocurable composition having same, and the use of same in the photocuring field. The fluorene photoinitiator has a structure shown by formula (I), wherein X is -A-(X')n; A is selected from heteroatoms selected from O, N or S; X' is selected from a C1-C20 linear or branched alkyl, a C3-C8 cycloalkyl, and a C1-C10 alkyl substituted with a C3-C8 cycloalkyl, or one or more of the carbon atoms in X is replaced with a heteroatom; n is 1 or 2; and R4 is a hydroxy or N-morpholinyl; or, the fluorene photoinitiator includes a structure shown by formula (II). The introduction of a new group on an existing fluorene structure not only increases the molecular weight of the photoinitiator, but also improves the relevant performances, such as initiation efficiency, of the photoinitiator.
