Abstract
A high-opacity cellulose-free synthetic paper is formed from a wet-laid nonwoven web of thermoplastic fibers, all or most of which fibers are made of a predetermined polymeric material. The wet-laid web is dried to remove excess water, drying being carried cut at temperatures below the melting temperature of the predetermined polymeric material. The dried nonwoven web is saturated on at least one side with a pigmented binder forming a continuous coating thereon. The binder is cured at temperatures below the melting temperature of the predetermined polymeric material.
