Abstract

The invention relates to a UV curable offset color changing ink as well as a preparation method and application thereof. The UV curable offset color changing ink comprises the following components bymass percentage: 1-3% of photochromic powder, 4-17% of light variable microcapsule toner, 10-30% of an epoxy acrylate oligomer, 20-60% of a polyester acrylate oligomer, 1-4% of flexible resin, 3-20% of a reactive diluent, 5-10% of a photoinitiator, 3-8% of an amine co-initiator, 2-8% of a filler, 0.5-2% of wax powder, 0.5-2% of spherical fine powder, 1-6% of a dispersant, 0.01-0.3% of an antifoaming agent and 0.2-0.6% of a leveling agent. The UV curable offset color changing ink provided by the invention has no solvent evaporation, is environmentally-friendly, pollution-free, fast in curing and high in efficiency, and has a reversible photochromic function after natural light and UV illumination and an excellent discoloration effect.

Description

technical field [0001] The invention belongs to the technical field of printing inks, and in particular relates to a UV curing offset color-changing ink and a preparation method and application thereof. Background technique [0002] With the progress of society and the improvement of people's requirements for material living standards, newer and higher requirements are put forward for inks, which not only require functionality and interest, but also require environmental friendliness. At present, the research on color-changing inks is mostly limited to screen printing and gravure printing, but with the steady development of my country's offset printing market, offset printing inks have developed rapidly. According to reports, the proportion of offset printing inks in my country's ink market has risen to 50% to 60%, but the research on offset color-changing inks is almost zero. At the same time, the existing color-changing inks contain a large amount of volatile solvents, whic...
