From the aspect of printing adaptability, flowed based on solvent-borne type black liquid.However, in recent years from the viewpoint of earth environment is saved from damage,
In flexible packing material market, since the air discharge of the solvent vapour from solvent-borne type black liquid can cause environmental pressure to increase, because
This is gradually considered as problem.Therefore, for the purpose of significantly cutting down solvent usage amount, the Water-borne modification of black liquid is being promoted.
On the other hand, in the packaging towards health products such as detergent, soap, these product compositions etc. can scheme with printing
Case contacts, and is considered the water soluble acrylic acid that water dispersible is better and is used as adhesive for printing black liquid etc. before this
It is that lotion does not have alkali resistance, the problem of damaging printed pattern dissolved can be produced.Therefore, it is proposed to employ can obtain it is resistance to
The water-based printing black liquid of the ethylene-acrylic copolymer of the good film of medicine manufacture method (such as patent document 1 and
2) black liquid of special surfactant (acetylenediol class), is coordinated with specific ratio in identical resin component and pigment
Composition (such as patent document 3).However, black liquid is made in the operation for disperseing pigment, using ink composition in addition
Operation in, can also it is different with the species of pigment and because produced immiscible between raw material gelation, solid part precipitation,
Floating etc..In addition, in the case where being disperseed pigment using surfactant, to the profit of the low polar plas film base material such as polyethylene
Moist variation, the printing such as become easily to cause printed article concentration to reduce are bad etc., there is performance of the infringement as printing black liquid
The problem of.
