ABSTRACT:
Room temperature curable latices can be produced by copolymerizing ketimine derivative ethylenically unsaturated monomers with conventional ethylenically unsaturated monomers in an emulsion process at a controlled pH greater than about 7.2 to produce a coagulum-free latex containing blocked amine (--NH.sub.2) groups. In use, the pH of the latex can be adjusted to acidic below 7 to generate unblocked reactive amino groups which can be cured or cross-linked at about room temperature with water-dispersed polymers such as epoxy, double bond or isothiocyanate containing polymers.
