Compound webs with improved absorption and pliancy are described. The compound web includes: (a) protrusions in each ply at a frequency greater than 10 protrusions/cm.sup.2 and with the surface of the peaks of the protrusions of each ply being greater than 5% of the surface of the ply, and (b) at least one of the plies being embossed in the form of an artistic pattern wherein the distances and the directions of an arbitrary protrusion relative to adjacent protrusions are varied. The pattern is selected in such a manner that at least 25% of the protrusions of the ply take part in effective bonding with the coinciding protrusions of the other ply and the total bonded surface of the protrusion peaks of the ply that take part in bonding is at least 15% of the total surface of the peaks of the protrusion of the ply regardless of the relative positions of the patterns of the two plies.

[ It is claimed:] [1.]1. A compound web comprising at least two plies of absorbent paper and having a specific surface weight of 10 to 40 g/m.sup.2, said at least two plies being embossed by calendering into patterns, said patterns comprising protrusions which are mutually bonded between plies at peak surfaces of coinciding protrusions, wherein(a) density of protrusions in each ply of said at least two plies is between 10 and 30 protrusions/cm.sup.2 and the surfaces of the peak protrusions of each ply exceed 5% of total surface of said each ply, and(b) at least one of the at least two plies is embossed with an artistic pattern wherein distances and directions of any protrusions to adjacent protrusions are varied, said artistic pattern being selected so that from 25% to 70% of the protrusions of said at least one ply effectively bond with coinciding protrusions of another ply and so that total surface of protrusion peaks being effectively bonded of said at least one ply is at least 15% of total surface of protrusion peaks of said at least one ply regardless of relative positions of each artistic pattern of the at least two plies.
