SELF-PHOTOINITIATING WATER-DISPERSABLE ACRYLATE IONOMERS AND SYNTHETIC METHODS

The invention detailed herein comprises a family of novel multifunctional acrylate ionomeric resins, which are water-dispersible, and have built-in photoinitiator. The inventive resins are made self-photoinitiating by their reaction with beta-keto esters (e.g., acetoacetates), beta-diketones (e.g.,...

Beschreibung
Zusammenfassung:	The invention detailed herein comprises a family of novel multifunctional acrylate ionomeric resins, which are water-dispersible, and have built-in photoinitiator. The inventive resins are made self-photoinitiating by their reaction with beta-keto esters (e.g., acetoacetates), beta-diketones (e.g., 2,4-pentanedione), beta-keto amides (e.g., acetoacetanilide, acetoacetamide), and/or other beta-dicarbonyl compounds that can participate in the Michael addition reaction as "Michael donors." These water-dispersible resins cure under standard ultraviolet (UV) cure conditions to give tack-free coatings without the addition of traditional photoinitiators. The present invention further relates to the use of these resins in coatings.
