ABSTRACT OF THE DISCLOSURE The present invention relates to an improved book- binding process comprising the use of an aqueous primer adhesive composition containing ungelatinized starch. A layer of the primer adhesive is coalesced to a resilient hinge by the application of a hot-covering adhesive without the need for an intermediate drying step. The coalesced film of primer adhesive provides a suitable underlying sub- strate for the adherent covering adhesive which binds the cover stock to the finished book.
