である。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a water-based pigment ink, and more particularly to a water-based pigment ink with excellent dispersion stability and corrosion resistance.
(従来の技術)
従来より、水性顔料インキは耐水性、耐光性に優れてお
り、各種用途に使用されている。(Prior Art) Water-based pigment inks have conventionally been excellent in water resistance and light resistance, and have been used for various purposes.
(発明が解決しようとする問題点)
然し乍ら筆記具用インキ等の低粘度での使用は顔料の分
散性が不安定で凝集しやすく、経時により筆記不能とな
るという問題があった。又。(Problems to be Solved by the Invention) However, when using a low viscosity ink for writing instruments, etc., there is a problem that the dispersibility of the pigment is unstable and tends to aggregate, making it impossible to write with the ink over time. or.
金属製のペン先等の金属部材を使用した場合。When using metal parts such as metal pen nibs.
インキ中に含まれる腐食成分のため金属部材が腐食し、
筆記不能となるという問題があった。Metal parts corrode due to the corrosive components contained in the ink,
There was a problem that it became impossible to write.
(問題を解決する為の手段)
本発明者等は上述せる水性顔料インキの分散性及び耐腐

部材を腐食させることがなくなるということを見い出し
本発明を完成したものである。即ち本発明は顔料と、下
記一般式(I)で示されるスチレン−アクリル酸共重合
物と、ベンゾトリアゾールと、水溶性有機溶剤と、水と
から少なくともなる水性顔料インキを要旨とするもので
ある。(Means for Solving the Problem) The present inventors conducted various studies to improve the dispersibility and corrosion resistance of the water-based pigment ink described above, and as a result, the following general formula (I
The present invention was completed based on the discovery that the combined use of the styrene-acrylic acid copolymer shown in ) and benzotriazole stabilizes the dispersibility and prevents metal members from corroding. That is, the gist of the present invention is an aqueous pigment ink comprising at least a pigment, a styrene-acrylic acid copolymer represented by the following general formula (I), benzotriazole, a water-soluble organic solvent, and water. .
(作用)
本発明の水性顔料インキが何故分散安定性及び耐腐食性
忙優れるかは以下の様に推察される。(Function) The reason why the aqueous pigment ink of the present invention has excellent dispersion stability and corrosion resistance is surmised as follows.
ベンゾトリアゾールは鋼糸の腐食防止剤として公知のも
のであるが、水性顔料インキに使用した場合、顔料の分
散系をくずしてしまいインキが凝集するため使用できな
かった。しかし。Benzotriazole is known as a corrosion inhibitor for steel threads, but when used in water-based pigment inks, it could not be used because it would destroy the pigment dispersion system and cause the ink to coagulate. but.
前記一般式(I)で示されるスチレン−アクリル酸共重
合物と併用することにより顔料の分散系をくずすことな
く腐食防止作用を示す。これは顔料表面に前記一般式(

し、その外側にベンゾトリアゾールが化学的に吸着して
いるためと思われる。When used in combination with the styrene-acrylic acid copolymer represented by the general formula (I), it exhibits corrosion-inhibiting action without destroying the pigment dispersion system. This is because the general formula (
1) This is probably because the styrene-acrylic acid copolymer shown in c-adsorbs and the benzotriazole is chemically adsorbed on the outside thereof.
