Document Type and Number:
Japanese Patent JP5566276
Kind Code:
B2
Abstract:
The invention relates to self-crosslinking aqueous polyurethane dispersions containing a crosslinking agent I selected from diamones I1 and dihydrazides I2, and polyurethanes comprising structural elements derived from polyisocyanates A, polyols B having a number average molar mass Mn of at least 400 g/mol, compounds D comprising at least two groups which are reactive compared to isocyanate groups and at least one group able to form anions, low-molecular polyols E that carry no other reactive groups compared to isocyanate groups, compounds F containing at least one group which is reactive compared to isocyanate, and at least one aldehyde-type or ketone-type carbonyl group, and compounds G that are monofunctional compared to isocyanates or contain active hydrogen with different capabilities of reaction and are different from the compounds E. The invention also relates to methods for the production of said dispersions, and coating agents containing the same.
