But, in recent years from the viewpoint of save global environment from damage, in flexible packing material market, owing to environmental pressure can be caused to increase from the airborne release of the solvent vapour of solvent based ink liquid, therefore it is regarded as problem gradually. Therefore, significantly to cut down for the purpose of solvent usage quantity, advancing the Water-borne modification of ink liquid.
On the other hand, in the packaging towards the health product such as washing composition, soap, these product compositions etc. can contact with printed patterns, and be considered to water dispersible aqueous acrylic acid series emulsion that is comparatively good and that use as the tackiness agent etc. of printing ink liquid before this and there is no alkali resistance, can produce problem that printed pattern dissolved is damaged. Therefore, it is proposed have employed the manufacture method (such as patent documentation 1 and 2) of the water-based printing of the ethylene-acrylic copolymer that can obtain the good film of resistance to chemical reagents ink liquid, coordinate the ink composition (such as patent documentation 3) of special tensio-active agent (acetylenediol class) in identical resinous principle and pigment with specific ratio. But, in addition by the operation of pigment dispersion, use in operation that ink composition makes ink liquid, also can be different and produce the precipitation, floating etc. of gelation, solid part because of immiscible between raw material along with the kind of pigment. In addition, when utilizing tensio-active agent by pigment dispersion, to the worsened wettability of the low polarity plastic film substrate such as polyethylene, it becomes easily cause the printings such as print concentration reduction bad, there is the problem of infringement as the performance of printing ink liquid.
