Versuchsvorschrift

An o-hydroxybenzylamine compound of the present invention composition was prepared according to the procedure of Example 1, except that 50 g of 4-t-butylphenol was employed in place of the Bisphenol-A, 20.1 g of ethanolamine was employed in place of the 2-(methylamino)ethanol, and that heating of the reactants was only begun after the formaldehyde addition was completed. A 0.5 g sample of the product was dissolved in 500 ml of ethanol/water (1:4 by volume) and the pH of the solution was adjusted to 3.0 with phosphoric acid.
