As the hydrogenated resin contains saturated chemical bonds, the double bonds are hydrogenated to form saturated chemical bonds, and the hydrogenated resin is more light-resistant and harder in hardness under the action of ultraviolet rays and other light rays, so that the hydrogenated resin has better oxidation resistance, heat resistance, light resistance and other performances.
Through the addition of the gel, a chelating bridging structure with strong affinity is formed between the gel and phenolic resin, soybean oil, mineral oil and carboxyl and hydroxyl of the organic pigment in the formula, so that the prepared ink has the capability of adapting to high-speed printing.
