With the improvement of social progress and people's awareness of environmental protection, water-based ink in the field of packaging printing ink has attracted much attention.Water-based ink is more widely used in the fields of paper, food, medicine, packaging and printing because it has very low organic volatile matter (VOCs) and green environmental protection. However, in the field of gravure printing based on polyvinyl chloride (PVC) plastic film material, it has just begun to develop.This is mainly because water-based ink in PVC and other plastic surface packaging printing still has poor color fastness to light poor adhesion poor dry slow packaging printing dark gloss and easy to appear small white spots and other shortcomings, resulting in not all aspects of application and promotion.

Water-based ink is water as a solvent or dispersant of the ink, which is mainly composed of linking pigment and additives known as ink heart water-based ink connecting material is the technical key to deal with the above problems.Water-soluble resin linker is the universal linker of water-based ink, which usually selects synthetic resin with high acid value, and then neutralizes into salt through volatile amine reagent.At this stage the study of water-based ink connection material mainly gathered in the synthesis of modified this aspect, such as using butyl acrylate, methyl methacrylate acrylic hydroxyl propyl acrylate and diacetone acrylamide as monomer, adipic acid hydrazide as crosslinking agent, according to the indoor temperature since the crosslinking reactions used in water-based ink water-based acrylic resin was synthesized.The water-based ink prepared from this resin was printed on polyethylene (PE) plastic substrate. The results show that it has the characteristics of low water absorption and good film forming ability and high fastness to adhesion.In addition, there are also many scholars on the thermal stability of water-based ink connectors, water fastness, drying rate, resolubility, hardness, impact resistance, solvent resistance and other properties carried out research.

The water-based polyurethane with high solid content was prepared by using small molecular chain extender of diisocyanate and polyester polyol with symmetrical structure, which achieved good water resistance, drying rate, thermal stability and fastness to adhesion.From the current literature, there is little research on the influence of water-based ink connectors on color fastness to light in plastic printing.Although the influence of water-based ink on color fastness to light in PVC edge-sealing strip printing was studied, the factors affecting color fastness to light were not analyzed, and the water-based ink bonding material was not further explored.Therefore, it is of great significance to study the influence of water-based ink connectors on the color fastness to light of PVC plastic printing.
