Description
Technical Field
The invention relates to the technical field of novel UV (ultraviolet) light radiation free radical polymerization materials, in particular to a UV light curing composition containing a fluorenylaminoketone photoinitiator.
Background
In 1988, patent EP284561 disclosed the use of α -aminoketones as photoinitiators, and finally 2-dimethylamino-2-benzyl-1- (4-morpholinophenyl) -1-butanone was chosen as a commercial product. However, the photoinitiators have the obvious disadvantages of low solubility, difficult formulation and poor low temperature stability of the formulated compositions, especially at concentrations above 5%. In 2001, patent document JP2001348412A discloses a liquid curable resin composition containing 2-methyl-1- [4- (methylthio) phenyl ] -2- (4-morpholinyl) -1-propanone (trade name Irgacure 907) as a photoinitiator component. However, since the aromatic ring system in the structure of the compound contains a methylthio group, there are inevitable problems such as generation of a bad smell after photocleavage and severe yellowing of the cured product, which are not applicable in the fields of food packaging, varnish coatings, white inks, and the like.
In view of the above drawbacks, in recent years, there have been reports on the research on Irgacure 907 photoinitiator substitutes, for example, patent application No. CN101724099 discloses a series of α -aminoketones of biphenyl derivatives, in which 1- ([1, 1-biphenyl ] -4-yl) -2-methyl-2-morpholinopropan-1-one is an effective substitute for Irgacure 907. The compound does not contain sulfur element, and shows excellent yellowing resistance when being applied to a UV free radical photopolymerization curing system, and no bad smell is generated after illumination decomposition. However, in practical application, the photoinitiator is found to be not a perfect substitute because of poor solubility, easy sublimation and pollution to production equipment and light sources.
These problems have attracted much attention in the industry, and the problems of odor, yellowing, toxicity and the like of the photoinitiator greatly limit the application of UV coatings and UV inks in various fields of furniture, electric appliances, automobile interiors, cigarettes, food, medicines, cosmetics and the like. Development of a photocurable composition that can effectively solve the above problems and is economically and environmentally competitive is one of the important issues facing the industrial field.
