The present invention relates to substrates and coating compositions disposed thereon containing improved ultraviolet degradation resistance. Specifically, these coating compositions can contain multiple UV protectants and can advantageously be used in transparent, semi-transparent, and/or translucent coatings on substrates, particularly opaque or semi-opaque substrates such as wood, e. g. , in order to inhibit, to reduce, and/or to minimize UV degradation of said substrates.

The present invention relates to an aqueous coating composition comprising a treated latex polymer dispersion with less than about 50 ppm of unreacted monomers. The latex polymer dispersion can be treated by various means, including stripping and chasing, to remove unreacted monomers from the dispersion. Unreacted monomers significantly contribute to paint odor. In an innovative aspect of the present invention, the synergistic combination of the treated latex dispersion with pigments and other low or zero-VOC additives results in an aqueous coating composition with de minimis levels of volatile emissions, low odor, and paint performance comparable to premium latex paints.

The present invention relates to water soluble open time extenders, which are mixed with an architectural coating, such as aqueous latex paints, to increase the coating's open time and crosslink to the architectural coating upon drying. The open time extender comprises neutralized water soluble polymers with hydrophobic, hydrophilic and cross-linkable monomers, and at least one crosslinking agent. The open time extender also comprises water and the total solid content of the open time extender is less than about 25% by weight.

The present invention is directed to an aqueous architectural composition comprising a low Tg (less than about −10 C. and higher than about −50 C.) acrylic emulsion polymer with at least one cross-linkable moiety, and solid polyutherane (PU) or polybutylacrylate microspheres having a mean weight diameter of less than about 40 microns and a Tg of less than about 0 C., wherein the solid PU spheres make up about 10% to about 20% by weight of the composition. The solid acrylic polymer without water and the PU spheres make up about 30% to about 40% by weight of the aqueous composition. A dried paint film formed by the inventive aqueous architectural composition can withstand at least about 500 cycles on the scrub test, and a gloss value at 60 of less than about 2.5 GU.

Water-borne cross-linking polymeric compositions and related embodiments, such as methods of making and using the compositions, as well as products formed with said compositions are described. The water-borne composition may comprise one or more polymers formulated from one or more monomers of which at least one is a monomer that yields acetaldehyde as a hydrolysis product, and incorporating cross-linking functionality such as, but not limited to, carbonyl or epoxy functionality, and a blocked cross-linking agent, for example, a hydrazone. Neither the cross-linking functionality nor the acetaldehyde reacts with the blocked cross-linking agent; however, the blocked cross-linking agent is capable of conversion to an alternative form cross-linking agent such as, but not limited to, a hydrazide, to yield a cross-linked polymer. The alternative form cross-linking agent may be formed in an equilibrium reaction including the blocked cross-linking agent.

The present invention is directed to a coating composition comprising a vinyl acrylic copolymer latex wherein said copolymer latex has a water contact angle of about 60 or higher on the dried latex film surface, wherein said copolymer latex further has a specific water vapor permeability of about 0.5 mg/cm/mm/24 hr. The invention is also directed to the copolymer latex itself. Further, the invention is a method of improving a coating's ability to withstand a high humidity environment comprising adding a vinyl acrylic copolymer latex to the coating composition wherein said copolymer latex has a water contact angle of about 60 or higher on the dried latex film surface, and wherein said copolymer latex further has a specific water vapor permeability of about 0.5 mg/cm/mm/24 hr.
