Modified water soluble polymer crosslinking agents can be used by themselves or in combination with conventional crosslinking agents, other crosslinkable base polymers, and/or hardeners. The dried composition is redispersible in water prior to crosslinking, but is stable to water after crosslinking, also offering improved stain resistance.
