The novel fast-drying pressure-sensitive adhesives comprise a polymer of a terminally unsaturated vinyl monomer such as isooctyl acrylate and an emulsifier monomer such as sodium styrene sulfonate plus a phosphate emulsifier, especially certain polyoxyethylene phosphates or salts thereof. Pressure-sensitive adhesive tapes comprise a backing and the novel adhesive. The novel tape is particularly useful as an automotive masking tape, because it both adheres strongly and can be cleanly removed from automotive paints after typical baking cycles. As compared to prior tapes the novel tapes have equal or better adhesive performance, with a faster drying adhesive layer. The tapes can therefore be produced more economically. Furthermore, there is no adhesive bubbling problem at commercially useful production rates as with the prior art when using a paper backing.
