The present invention relates to a water-containing coating composition thickened with a hydrophobically modified alkali soluble emulsion, wherein the composition is neutralized by a combination of an alkali metal hydroxide or ammonium hydroxide and a low VOC alkanolamine.

Hase-thickened composition

Functional gel particle formed from a crosslinked polymeric network including a fraction of stable crosslinks and a second fraction of cleavable crosslinks are disclosed. Functional compounds may be chemically or physically encapsulated within and/or released from the gel particle by selective cleavage of the cleavable crosslinks. The functional compounds may be delivered and released to a pre-selected target site. Peripheral or other accessible functionality on the surface of the gel particle allows attachment of a surface reactive agent, thereby modifying one or more surface properties of the gel particle. Processes of preparing the gel particles and processes of delivering the functional compounds to a target site are also disclosed.
