Conditions

Temperature: 60 °C

Procedure

The same classes of materials were also prepared by using appropriate metal alkoxides and hydroxysulfonic or sulfocarboxylic acids in water. Thus, aluminum isopropoxide was mixed with 5-sulfophthalic acid in 2:3 molar ratio and the mixture was heated to about 60° C. for about ½ hr. Aluminum isopropoxide was hydrolyzed and the salt was obtained as aqueous solution and was used as such for inkjet coatings. Magnesium ethoxide was similarly hydrolyzed from its mixture with the same acid in 1:2 molar ratio to obtain magnesium sulfophthalate in aqueous solution.
