    摘要: This invention relates to a multilayer coating system derived from Titanium dioxide free aqueous coating compositions. The multilayer coating system comprises at least two layers including a layer of base coating which provides good hiding function for substrates and a second layer of clear top coating which provides surface protection functions for the coating system. The base coating composition comprises an opaque (co)polymer having at least one void per (co)polymer particle. The top coating composition comprises a duller (co)polymer chosen from a multi-stage (co)polymer, a single stage crosslinked (co)polymer, and mixtures thereof.

    摘要: The present invention relates to an aqueous copolymer dispersion comprising an emulsion copolymer and two hydrophobic aromatic ketones, wherein the aromatic ketones are, based on the dry weight of the copolymer, from 0.1 to 3 wt % benzophenone and from 0.1 to 4 wt % a benzophenone derivative; wherein the dispersion comprises 0 or less than 0.1 wt % hydrophilic aromatic ketone. The copolymer dispersion is suitable for preparation of aqueous coating compositions which yields a relatively hard surface to provide not only short term but also long term dirt pick up resistance effects, after exposure to ultraviolet radiation.
