Abstract
A multi-ply paper product. One or both of the plies may have embossments protruding towards and contacting the other ply. The plies are adhesively joined, preferably at such embossments. The adhesive is selected from a composition that advantageously provides a minimum wet ply bond strength and a dry ply bond strength which falls within a particularly desired range.
