A two-phase acidic aqueous composition for use as a neutralization layer is generally comprised of a water soluble aqueous phase and a water insoluble particle phase. The particle phase generally comprises a copolymer having recurring units of an organic acid monomer and an organic ester monomer. The aqueous phase comprises a water soluble polymer having recurring units of at least an organic acid monomer. The organic acid monomers selected for the aqueous phase polymer are capable of interacting with the particle phase polymers such that the particle phase polymers are brought into stabilizing, intimate association with the aqueous phase.
