Polymer for light-assisted curing of coatings and method for producing it |
摘要 |
A process of preparing a coating for application to substrates which are exposed to ultraviolet light is described which comprises mixing a vinyl polymer having acetoacetyl functional groups with an amount of ammonia or primary amine sufficient to convert the acetoacetyl groups to enamine, storing the mixture for a period sufficient to allow the reactants to equilibrate, adding a sufficient amount of ammonia or primary amine to raise the pH to about 9, and maintaining the pH at about 9 until the coating is applied to the substrate. |
