Easy-to-clean aqueous metal-printing ink

Abstract

The easy-to-clean out aqueous metal-printing ink as one kind of water soluble printing material is compounded with connecting material, assistant, pigment and diluent. It may be used in printing and hot transferring metal foil and may be cleared and recovered at high temperature over 250 deg.c. It has no environmental pollution, and as one kind of newly developed clean printing material, it may be used widely in printing various metal foils and metal plates.

Description

technical field [0001] The invention belongs to the scope of printing and dyeing materials, in particular to an easy-to-clear water-based metal printing ink. Background technique [0002] The inks used in the printing industry are generally used for paper printing or inkjet printing of documents by printers, or for direct writing and printing on metals. However, this kind of ink has low temperature resistance and contains harmful components that will cause environmental pollution. Chinese patents 02124255.0, 97111774.8 and 96101181.5 propose a clean printing and dyeing technology, which directly prints patterns on the metal foil through the printing area, and the patterns on the metal foil are transferred to the substrate by hot pressing; the metal foil has The residual pattern can be removed, and the clean foil is recycled to the printing area for repeated use. After the realization of this clean printing and dyeing technology, it can solve the problem of a large amount of...
