Nano silver dispersion and jet printing ink

Abstract

The invention provides a nano silver dispersion comprising sulfonate base water dispersible polyester which is a random copolymer with the molecular formula as follows: R1 or R2 independently comprises OCH2CH2, OCH2CH2CH2CH2 or nano silver solution. The invention also provides a jet printing ink comprising the nano silver dispersion.

Description

Nanometer Silver Dispersion Liquid and Its Jet Printing Ink technical field The invention relates to a nano-silver dispersion liquid capable of uniformly dispersing nano-silver, and in particular to a jet printing ink containing the nano-silver dispersion liquid, which has good electrical conductivity and strong adhesion to substrates. Background technique Since the printing preparation process has the advantages of energy saving and material saving, it is currently being actively developed to replace such as optical filters for LCDs, brightening diffusers for LCDs, transparent electrodes for photoelectric components, printing photoresists for PCBs, The yellow light lithography preparation process of today's electronic / optoelectronic industry such as LED chip packaging. Moreover, if the silver wires can be formed by the jet printing preparation process, it will bring greater benefits to the industry, and the most important key material of this preparation process is conduc...
