Abstract:
A composition comprising:(1) at least one polymer (A) chosen such that a film obtained by drying a mixture of said at least one polymer (A) and at least one solvent chosen from ethanol and water, at room temperature and at a relative humidity level ranging from 45% to 55%, exhibits a mechanical profile defined by at least: (i) a degree of elongation at break (&egr;b) of greater than or equal to 300%; and (ii) a degree of recovery at 300 seconds (R300) of greater than or equal to 45%; with the proviso that when said degree of recovery at 300 seconds ranges from 45% to 60%, said degree of elongation is less than 1300%; and (2) at least one film-forming polymer (B), different from said at least one polymer (A), chosen from anionic film-forming polymers, cationic film-forming polymers, and amphoteric film-forming polymers.
