ABSTRACT:
A monosecondary amine containing blocked primary amine groups is provided by reacting a monosecondary amine containing at least one primary amine group (such as diethylene triamine) with a ketone which is hindered to prevent reaction with secondary amino hydrogen atom (such as methyl isobutyl ketone) while removing water. This product disperses in water with the aid of a solubilizing acid to provide a solution which will emulsify a liquid polymer dispersed therein. The water hydrolyzes the blocked primary amine groups to restore reactivity. This product can also be reacted with 1,2-oxirane or isocyanate-functional polymers to provide products which are dispersible in water with a solubilizing acid. These dispersions will electrodeposit at the cathode.
