素が存在し、耐アルカリ性が悪いという欠点を有する。The above composition is applied to a substrate and fired, but if the firing temperature is low, the hardness of the coating will be insufficient, and if the firing temperature is high, the hydrocarbon groups will break off and the shrinkage rate will increase, causing cracks and pinholes to prevent corrosion. Sexuality decreases. Furthermore, silicon dioxide is present in the coating, which has the disadvantage of poor alkali resistance.

Finely powdered alumina with a diameter of 1O-6 to I+ is colloidally dispersed in water, and the shape of the fine alumina powder may be granular or fibrous. . The pH of the aqueous dispersion is preferably acidic and 3 to 7, since alumina will aggregate if it is alkaline. In addition, the larger the amount of aluminum dispersion, the more likely it is to aggregate, so 6 to 1
Preferably, the amount is 5 wt%.

However, as the alumina component increases, the alkali resistance decreases, and conversely, as the zirconium component increases, the water resistance decreases. Ajt 01 because acid resistance etc. decreases.
The converted value of ZrO3 is preferably 9=1 to 1:9, more preferably 8:2 to 5:5.

．． After ultrasonic cleaning with acetone (φ600Vf machining, BA finish), it was immersed in the obtained coating composition and washed for 10 minutes.
It was bowed at a speed of 0c+++/- and dried for one day at room temperature. Next, the temperature was increased to a predetermined baking degree shown in Table 1 at a rate of 50° C./br, and then baked for 2 hours to obtain a stainless steel plate with a coating layer formed thereon. The thickness of the obtained coating layer was measured and the appearance was visually observed, and the results are shown in Table 1. In addition, pencil hardness (JIS K 54
