AQUEOUS SOLUTIONS OR DISPERSIONS OF OLIGORUETHANES CONTAINING (METH)ACRYLOYL GROUPS, A PROCESS FOR THEIR PRODUCTION AND COATED SUBSTRATES PREPARED THEREFROM

The present invention relates to aqueous solutions or dispersions of oligourethanes having a pH of 6.0 to 8.5 wherein the dissolved or dispersed oligourethanes contain carboxyl groups at least partially neutralized with ammonia and have i) a double bond content in the form of (meth)acryloyl groups (...

Beschreibung
Zusammenfassung:	The present invention relates to aqueous solutions or dispersions of oligourethanes having a pH of 6.0 to 8.5 wherein the dissolved or dispersed oligourethanes contain carboxyl groups at least partially neutralized with ammonia and have i) a double bond content in the form of (meth)acryloyl groups (expressed as C=C, molecular weight 24) of 3 to 15% by weight and ii) a content of carboxyl groups, including the carboxyl groups neutralized with ammonia, which corresponds to an acid value of 20 to 100. The present invention also relates to a process for the preparation of these aqueous solutions or dispersions of oligourethanes and to their use for the preparation of coated substrates.
