Description

technical field [0001] The invention relates to ink for color printers. Specifically, it relates to an environmentally friendly ink for food packaging color painting. Background technique [0002] The known ink used for food packaging color painting is oil ink. Because the oil contains carcinogens to the human body, if it is absorbed by the human body, it will affect people's health. In order to prevent this disadvantage, general ink manufacturers use water-based dye ink to eliminate this disadvantage. Water-based dye ink cannot absorb the visible spectrum, which also affects the color vividness of product packaging. At the same time, because water-based dye ink is added with industrial ethanol and other chemical substances, it cannot fundamentally solve the quality and hygiene requirements of food packaging color painting ink. Contents of the invention [0003] The object of the present invention is to provide an environmentally friendly ink for food packaging color draw...
