Abstract
The present invention provides an adhesive composition that is useful as an energy-curable, one-part adhesive, suitable for bonding electronic components. The adhesive composition, preferably provided as an adhesive film, comprises the reaction product of an admixture of an effective amount of a curable cyanate ester resin, a thermoplastic polymer, and a curing catalyst. The catalyst may be, for example, thermally or photochemically activated.
