An aqueous emulsion comprising a bilayer copolymer is produced by polymerizing at least one aqueous vinyl monomer component (II) in the presence of a seed emulsion containing 10 to 50 wt% of (meth)acrylonitrile among comonomer components. The obtained emulsion is resistant to heat, solvents and blocking, and used in a primer of release paper, a back treatment, binders for diazo paper and offset master, and so forth. |
