Abstract

The invention provides an oxetane compound, a photocuring composition, ink and application thereof. The oxetane compound has a general formula I, wherein R1 and R2 are respectively and independently selected from H, straight-chain or branched-chain alkane and aryl; R3 represents an alkane of C4 to C12, a monoether of C4 to C12, or a polyether of C4 to C12; and at least one carbon atom in C4 to C12is substituted by a carbonyl group or an ester group. When the oxetane is applied to light-cured ink for multi-layer printing, the surface tension of the cured ink is not obviously reduced, namely certain surface tension is maintained, the interlayer adhesive force is increased, color overlapping is facilitated, and the problem of poor recoatability is solved; the process that the substrate needsto be polished when the next layer of ink is plated is reduced; moreover, the surface tension performance of each layer of ink does not need to be independently limited, and the ink has universal applicability and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of printing, in particular to an oxetane compound, a photocurable composition, ink and applications thereof. Background technique [0002] The photocuring technology uses ultraviolet light to cause the photoinitiator in the system to undergo a photochemical reaction to generate free radicals, triggering the active double bond reaction in the monomer or prepolymer, so that the crosslinking is instantly cured. Compared with thermal curing technology, light curing has the advantages of fast curing, low energy consumption, high efficiency, wide adaptability and environmental friendliness. It has been widely used in printing, packaging, building materials, decoration, electronics and other industries. [0003] In the printing industry, the emergence of light-curable inks has solved the disadvantages of powder spraying on printed matter due to the ink not drying in the past, and the colors are more vivid and saturated, and ...
