  • Patent number: 6136895
    Abstract: The present invention can provide a cationic electrocoating composition, comprising:(a) an acrylic resin functioning as a leveling agent, which has both an amino group and an acid group in one molecule and has a hydroxyl value of 50 to 200,(b) a base resin, and(c) a crosslinking agent,wherein the acrylic resin (a) is formulated in an amount of 0.1 to 20 percent by weight, based on the total weight of a mixture of the base resin (b) and the crosslinking agent (c), and the cationic electrocoating composition is substantially free from lead compound. The present invention also provides a method for preventing cratering or cissing on an electrocoated film formed from the cationic electrocoating composition.
