Abstract
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.
