Abstract
Treated articles with improved water sheeting and soap scum repellency result from forming hydroscopic films on the surfaces of hydrophobic polymeric substrates treated with compositions, kits and methods that employ water-soluble or water-dispersible copolymers having: (i) a first monomer that is capable of forming a cationic charge on protonation; (ii) a second monomer that is acidic and that is capable of forming an anionic charge in the compositions; (iii) optionally, a third monomer having an uncharged hydrophilic group; and (iv) optionally, a fourth monomer that is hydrophobic. Treated articles exhibit a Water Sheeting Index of greater than 6. Treated articles may further exhibit improved soap scum repellency behavior compared to untreated articles.
