Vorschrift

0.1 M zinc nitrate and 1 M monobasic sodium phosphate were mixed while stirring to allow precipitates to be produced by heating at 80° C. twice. Centrifugal separation (2000 ppm, for 5 min) and washing with water were repeated five times to produce a zinc phosphate paste. The zinc phosphate paste was adjusted to give a solid content concentration of 20 parts by weight and to include methyldiethanolamine at 1 part by weight, and dispersion was made similarly to Example 1. The treatment liquid for surface conditioning was obtained by preparing it from the resulting concentrated dispersion liquid, in a similar manner to Example 1.
