摘要：
The present invention relates to a crumple-resistant security sheet comprising fibers; an anionic polymer in a proportion lying in the range 5% to 45% by dry weight relative to the total dry weight of the fibers, and presenting a glass transition temperature greater than 40° C.; and a main cationic flocculation agent in a quantity lying in the range 1% to 5% by dry weight relative to the total dry weight of the fibers.
