Composite particles and a method of preparing the composite particles are provided. The composite particles contain titanium dioxide particles with adsorbed two-phase polymer particles. The two-phase polymer particles have a soft polymer phase and a hard polymer phase in which the weight ratio of the hard polymer phase to the soft polymer phase is in the range of 10:1 to 1:5. The composite particles containing the two-phase polymer particles have improved aqueous stability and provide coatings with improved scrub resistance.
