Abstract
The present invention relates to a pre-paint composite comprising an aqueous slurry of TiOparticles and attached and unattached polymeric binder, and a sufficient amount of a secondary alcohol ethoxylate of the formula CHO(CHCHO)H to give 35 to 90 weight percent attachment of polymeric binder to the TiOparticles, based on the weight of total polymeric binder in the pre-paint composite, where x is from 15 to 50; and the O(CHCHO)H group is bonded to a CH group on the CHchain. The present invention also relates to a coatings composition containing the composite as well as a process for preparing the pre-paint composite and the coatings composition.
