行わしむるECD組成物に関するものである。[Detailed Description of the Invention] The present invention improves the contrast of pattern display and efficiently performs electrode reactions by displaying a white background or a color background in an electrochromic display (hereinafter referred to as ECD). The present invention relates to ECD compositions.

電極が見えるという不都合が生じる。 Typical electrochromic (hereinafter referred to as EC) substances that have been proposed include organic compounds such as viologen derivatives and inorganic compounds such as tungsten oxide (WO 3 ) and molybdenum oxide (MoO 3 ). When these ECD material layers are used in a solution state, the solution is transparent, and the colored EC material deposited on the display electrode alone does not provide sufficient contrast.
The disadvantage is that the material precipitates and the colored counter electrode is visible through the transparent solution layer.

る。 Conventionally, in order to improve these drawbacks, a porous separator was provided between the display electrode and the counter electrode to hide the counter electrode, and a pigment such as TiO 2 or an emulsion solution was used to create an ECD composition. A method was used in which the counter electrode was hidden by making it opaque. However, with the method of installing a separator, ECD
The cell structure became complicated, and there were also problems such as coloration of the separator due to interaction between the separator and the ECD composition. When using pigments such as TiO 2 , there is a problem in that the hiding rate decreases over time due to aggregation of dispersed particles. In the method using emulsion solution,
The decline in hiding rate over time can be suppressed, but when coloring
Emulsion particles are incorporated together with EC substances,
There was a problem that the color density decreased. This point is also a problem when using pigments such as TiO 2 .

る。 The ECD composition according to the present invention uses a colloidal particle emulsion solution charged with the same polarity as the polarity of the display electrode during coloring in order to improve display contrast and hide the counter electrode. This is due to electrostatic repulsion between the display electrode and colloid particles during coloring.
This is to reduce the density of colloidal particles near the interface of the ECD composition, and to prevent the adhesion of the colloidal particles to the display electrode and the reduction in coloring density due to the colloidal particles being incorporated into the coloring layer.

In order to control the charge of colloidal particles, an anionic surfactant is added to the EC substance that is colored at the cathode, and an anionic surfactant is added at the anode.
A cationic surfactant was used for the EC substance.

In particular, for the production of negatively charged emulsions, it is also effective to bond anions to the ends of the resin.

化させる効果をもつ。 The emulsion solution contains a supporting electrolyte and an EC
There are some substances whose dispersion state changes depending on the charge of the substance. In this case, it is necessary to appropriately select the concentrations of the supporting electrolyte, EC substance, emulsion resin and surfactant. Depending on the degree of coagulation and hydration of colloidal particles in the emulsion solution, the emulsion solution changes into a cream-like or gel-like state. In this case, it does not affect the EC effect, but has a particularly stabilizing effect on changes in concealment effect over time.
