Abstract

The invention provides an UV drying electroluminescent silk screen printing ink composition, which comprises the following components by weight percentages: 20-60% of UV solidification resin, 5-20% of electroluminescent material, 0.01-25% of pearlescent pigment, 3-20% of active monomer diluent, 4-12% of photo polymerization initiator, 0.01-40% of solvent and 0-10% of auxiliary agent. The printing ink composition simultaneously has multiple false proof characteristics easily identified by popular, such as pearly lustre, UV excitation fluorescence and electric field luminescence, cation is introduced in a free radical initiation system to initiates resin and vinyls monomers, and a problem that the printing of a high content fluorescence characteristic material printing ink composition is dry and a problem of combination fastness with a ink membrane base material can be solved.

Description

technical field [0001] The invention relates to an electroluminescence screen ink. Background technique [0002] Electroluminescent screen ink is an ink composition obtained by adding electroluminescent materials to screen ink, and is usually used in anti-counterfeiting fields such as cards and tickets. [0003] The Chinese patent applied by Matsushita Electric Industrial Co., Ltd. in Osaka, Japan, the application number is (200910131974.2). The ink composition includes polymer organic electroluminescent materials, organic solvents, and aromatic carboxylic acids and their ester derivatives. Due to the low content of aromatic carboxylic acid and its ester derivatives used as the linking material for the preparation of closed light-emitting devices in this patent, it cannot be used for surface printing or coating of open cards, tickets, etc. cloth. [0004] The Chinese patent jointly applied by Federal Printing Co., Ltd. of Berlin, Germany and Luminescent Materials Breitunge...
