Mono-stripped hydrogen light initiating agent, its production and use

Abstract

A mono-component hydrogen-abstraction initiating agent is prepared by reacting dihydroxy-alkyl-benzophenone, dicarboxyl-alkyl-benzophenone or bisamine-alkyl-benzophenone with acryloyl chloride, inducing into acrylate double bond and Michael reacting it with secondary amine or primary amine. It's simple, cheap and efficient, has excellent solubility and mobility. It can be used for coating, binder, printing ink, photo-etching and biological materials.

Description

technical field [0001] The invention relates to a single-component hydrogen abstraction type photoinitiator, a preparation method and application thereof, and belongs to the field of photosensitive polymer material preparation. Background technique [0002] Ultraviolet curing technology uses ultraviolet light as the reaction power, and acts on light-sensitive compounds through light to cause a series of photophysical and photochemical reactions to generate active substances, thereby initiating the polymerization of active monomers, and finally the liquid The resin is converted into a solid polymer material. As a new green technology, it has a wide range of applications in coatings, adhesives, printing inks, photolithography, and biomaterials. UV curing technology is characterized by energy saving, environmental friendliness, cost-effectiveness, compact photopolymerization device, and high production efficiency. In addition, compared with traditional curing technology, UV c...
