Document Type and Number:
WIPO Patent Application WO/2018/094960
Kind Code:
A1
Abstract:
The present invention relates to a cinnamic acid benzoyl methyl ester compound of formula (I), wherein R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13 and R14 are as defined in the description. The present invention also relates to a method for preparing the cinnamic acid benzoyl methyl ester compound of the present invention, comprising subjecting the compound of formula (II) and the compound of formula (III) to an esterification reaction. The compound of the present invention can be used as a photoinitiator, is capable of absorbing radiant heat in the range of 200-350 nm, has good stability and resistance to yellowing, and more importantly, such initiators have greatly improved in terms of odour and strong migration, compared with the existing α-monohydroxy ketone photoinitiators.
