N-acyl aminomethylene phosphonates and their use in waterborne coating compositions |
摘要 |
N-acyl aminomethylene phosphonates are provided having a group defined by the following general formula: <IMAGE> wherein R1 is hydrogen, an aliphatic radical having 1 to 25 carbon atoms, or an aromatic radical having 6 to 25 carbon atoms; R2 is hydrogen, an aliphatic radical having 1 to 25 carbon atoms, or an aromatic radical having 6 to 25 carbon atoms; and R3 is a group remaining after reaction of a hydroxyl group-containing or epoxy group-containing polymer with an acidic hydrogen of a <IMAGE> group. Also provided are waterborne coating compositions containing metallic pigments which are normally reactive with water or moisture to release hydrogen gas, stabilized against gassing by incorporation of these N-acyl aminomethylene phosphonates into the waterborne coating compositions.
