A solvent-less hybrid curable composition is prepared from grafting polyesters or polyamides onto a (meth)acrylic copolymer backbone. Besides the many benefits of a solvent-less system, the hybrid curable composition forms strong adhesion to polar substrates, widens the use temperatures, and enables faster processing speeds than conventional hybrid curable compositions. The solvent-less hybrid curable composition forms an optically clear single phase that is suitable as tapes and labels, or in electronic, optoelectronic, OLED and photovoltaic devices, and the like.

Curable adhesive compositions and use thereof

The present technology relates generally to aqueous dispersion or emulsion compositions that include a polymeric binder resin and an ether amine. Specifically, the polymeric binder resin includes acid functional groups, at least a portion of which are neutralized by the ether amine such that the polymeric binder resin is dissolved or dispersed in the water, provided that the polymeric binder resin is not a polyurethane and the ether amine is a compound of formula I: wherein Rand Rare independently C-Calkyl or C-Ccycloalkyl group; or Rand R, together with the nitrogen to which they are attached, form a C-Cmembered heterocycloalkyl ring; A is a C-Calkylene or C-Ccycloalkylene ring; and Ris C-Calkyl or C-Ccycloalkyl group; provided that the compound of formula I contains no more than 10 carbons.
