Abstract

La presente invención se refiere a una dispersión acuosa que comprende partículas poliméricas modificadas con alcohol polivinílico catiónico, a materiales acuosos de electrorrecubrimiento que contienen dichas dispersiones y a un proceso para producir un sustrato recubierto, al menos parcialmente, utilizando dicho material acuoso de electrorrecubrimiento. La dispersión acuosa puede prepararse haciendo reaccionar un intermedio que comprende al menos una cadena polimérica de alcohol polivinílico con un compuesto que comprende al menos un grupo epóxido y al menos dos grupos amino primarios bloqueados. Las composiciones acuosas de recubrimiento que comprenden dicha dispersión acuosa dan como resultado mejores propiedades de nivelación durante la formación de la película, así como una mejor protección de los bordes del sustrato sin influir negativamente en la rugosidad y adhesión de la superficie, así como en las propiedades de deposición.
