Abstract

A hydrido-silicone resin is incompletely reacted with an olefin under hydrosilylation conditions to produce a partially substituted hydrido-silicone that is further reacted under hydrosilylation conditions with a vinyl containing silicone to consume the remaining hydride species to produce a composition that is useful as an anti-mist agent in the coating of flexible supports.
