Abstract
Abstract A novel acrylic-siloxane paint binder resin that is crosslinkable with vinyl monomers by exposure to an electron beam is produced in a two step reaction wherein (1) a siloxane having two or more hydroxy or alkoxy functional groups per molecule is reacted with a hydroxy functional copolymer of acrylic monomers, and (2) the siloxane-comprising reaction product of the first reaction step is reacted with a C5 - C12 monohydroxy acrylate, e.g., the monoester of a C2 - C8 diol and acrylic or methacrylic acid.
