Abstract

A polymer composition providing improved curl benefits is disclosed. The composition includes a first weakly charged anionic polymer and a second weakly charged cationic polymer. When the polymer composition is applied to a Leneta card, the card has a minimum contraction of 10% as described by the “Contraction Test,” when the Leneta card is kept at a temperature in the range of 22 to 28° C. and at a relative humidity in the range of 40% to 50% to measure the contraction. Also, the first and second polymers are either water soluble or water dispersible and comprise from about 40% to about 99% identical chemical structure based on monomers in each polymer.
