COMPOSITION FOR CATIONIC ELECTRODEPOSITION PRIMER

Title:

COMPOSITION FOR CATIONIC ELECTRODEPOSITION PRIMER

Document Type and Number:

Japanese Patent JPS5911378

Kind Code:

A

Abstract:

PURPOSE: To provide the titled composition which improves interlaminar adhesion to topcoats, prepared by adding an organic acid salt of Mn, etc. to a resin having a specified reactive group.

CONSTITUTION: A reactive group-containing resin is prepared by interaction of (A) a compd. having a cathionic group (e.g. Epon 828 made by Shell Chemical Co.), (B) a compd. having a non-conjugated carbon-carbon unsaturated bond (e.g. liquid polybutadiene with a molecular weight of about 400W4,000 and an iodine value of about 50W600) and (C) a compd. having a blocked isocyanate group (e.g. 2-ethylhexanol-blocked toluene diisocyanate). The composition for cationic electrodeposition primer is prepared by adding an organic acid salt of Mn, Co, Ce and/or Fe (e.g. manganese naphthenate) to the above resin in an amount of 0.02W0.5wt% of the solid content of the resin.
