Abstract:
The dirt pickup resistance of substrates, in particular coatings, is improved by the incorporation of small amount of certain layered double hydroxide particles. Methods for the preparation of effective, readily intercalated, layered double hydroxide particles and compositions comprising them, such as architectural coatings, in particular water based architectural coatings, are provided.
