Electroluminescent flexographic printing ink and preparation method thereof

Abstract

An electroluminescent flexographic printing ink and a preparation method thereof. The ink includes, in parts by weight, the following components: 0.5 parts to 2 parts by weight of an electroluminescent material; 120 parts to 150 parts by weight of a monomer; 10 parts to 20 parts by weight of a prepolymer; and 0 part to 5 parts by weight of a leveling agent; wherein the electroluminescent ink for flexographic printing of the luminescent layer of the electroluminescent device does not comprise a pigment; and the electroluminescent ink for flexographic printing of the luminescent layer of the electroluminescent device has a particle size of less than 0.1 μm, a viscosity of 20 cP to 2,000 cP at 25° C., a surface tension of 18 mN/m to 37 mN/m at 25° C., and a curing time of 10 min to 30 min.
