Code-spraying printing ink

Abstract

The invention relates to a code-spraying printing ink. The code-spraying printing ink comprises optical-excitation fluorescence colorant, polymer resin, organic solvent and antistatic agent. A product marking (information) which is obtained by utilizing a code-spraying printing machine to print or spray the code-spraying printing ink on a product can be clearly identified under visible lights, can emit bright fluorescent lights under the excitation of special light sources (such as ultraviolet lights), and can be accurately and clearly exposed and read; and in addition, the product marking prepared from the code-spraying printing ink provided by the invention is suitable for substrates of various colors. The product markings prepared from the code-spraying printing ink provided by the invention on the substrates of various colors all can be accurately and clearly read, and simultaneously can be clearly identified under the visible lights of the substrates of multiple colors. The code-spraying printing ink has color discrimination performance and optical-excitation luminosity.

Description

technical field [0001] The invention relates to a code-jet printing ink, in particular to a code-jet printing ink with fluorescent components suitable for a quality traceability system. Background technique [0002] For products under the high-speed production line, when performing quality traceability, printing of inkjet information is required to form product identification on the product, and then camera collection is performed for these product identifications, and the collected data is entered into the system. The existing inkjet printing inks are mainly black inks, and the information printed by black inks can be clearly recognized by the naked eye. On the material, it is difficult to 100% of the printed information to be read by camera, which greatly limits the use effect of the quality traceability system. [0003] Due to the fast volatilization speed of the solvent, the solvent-based ink can form a fast-drying coating film on any material, which is suitable for the...

Problems solved by technology

However, the fluorescent substances used in previous solvent-based fluorescent inks are invisible under visible light, and it is difficult to balance color recognition and light-excited luminescence; in addition, fluorescent inks in water-based systems can only be applied to piezoelectric inkjet printing systems that are printed on demand , not suitable for continuous printing piezoelectric printing system, due to the slow evaporation of water, the general printing materials are permeable materials (paper products and fabrics), in non-permeable materials (metal, plastic , coating materials, varnish paper, etc.) are not easy to dry, and the ink surface tension of the water-based system is large, which affects the adhesion and other properties of the dried coating film
