A pressure sensitive adhesive emulsion comprises a disperse silicone phase emulsified in a continuous water phase in the presence of a surfactant. The disperse silicone phase comprises 40-80 percent by weight of a silicone pressure sensitive adhesive, which is the product of mixing a silanol-terminated polydiorganosiloxane of Tg below −20° C. with a silanol-containing silicone resin of Tg above 0° C., dispersed in 60-20 percent by weight of a volatile silicone fluid having a boiling point below 300° C. The emulsion is substantially free of any non-silicon atom containing volatile organic material.
