A case or cover for a hard bound book is formed by bonding the formed by bonding the cover boards to the book cover stock using a hot melt pressure sensitive adhesive composition comprising:

Toughened hot melt adhesive composition for book casemaking

Thus, the present invention is directed to hot melt adhesive compositions suitable for bookbinding application comprising tackifying resins, at least one wax diluent and a substantially radial styrene-butadiene block copolymer, the copolymer having a styrene content greater than about 35% by weight, a modulus at 300% elongation of at least 4.5 MPa and a solution viscosity less than about 1000 cps.

Remoistenable hot melt adhesives are prepared from a poly(alkyloxazoline), a diluent and, optionally, a tackifier, plasticizer, stabilizer and non-block additive.

Remoistenable hot melt adhesives

A hot-melt adhesive especially useful in the construction of disposable diapers contains a vinyl polymer of 40-90% by weight of a C.sub.1 -C.sub.12 alkyl acrylate and 10-60% by weight of an alpha-olefin of C.sub.20 -C.sub.40, wherein the alkyl acrylate may be partially replaced with vinyl acetate or with a C.sub.6 -C.sub.12 olefin or with mixtures thereof, provided that the polymer contain at least 10% by weight of the alkyl acrylate. The adhesive may also contain a tackifying resin, a wax, an oil or a stabilizer depending on the specific end-use desired. In a preferred embodiment the polymer contains 20-45% by weight of the alpha-olefin.
