However, although these rust-preventive pigments exhibit excellent rust-preventing properties for metals, they are toxic and their use has been gradually restricted due to demands for environmental purification.

定せず、しばしば塗料がゲル化する問題点がある。[0005] However, among these rust preventive pigments according to the prior art, zinc phosphate-based pigments, which are considered to be non-polluting white, have insufficient rust-preventive power, and phosphite-based pigments do not. Although relatively good results are obtained in terms of (1), the pigment properties when formed into a paint are generally deteriorated due to the tendency to become large particles, and there is a drawback that the rust prevention power varies. Besides,
There is a practical disadvantage that the manufacturing cost is high. Similarly, potassium phosphite phosphite-based rust preventive pigments using an organic phosphonic acid compound having chelating ability do not have stable pigment properties, and often have a problem that the paint gels.

On the other hand, the wet method is a method in which a slurry in which zinc oxide is dispersed in water is applied to a strong shearing dispersion device such as a colloid mill, a homogenizer, or a bead mill, and then an organic phosphonic acid having a chelating ability is reacted. In the wet method, phosphonic acid can be used as an alkali salt or an ammonium salt. After completion of the reaction, the reaction product is separated by filtration, washed with water as necessary, dried and pulverized to obtain a product.
