A continuous book binding process and a book comprising a backbone made by the process. The process comprises forming a book block, applying a wet coating of a primer composition to the spine area of the block, thermally drying said coating to remove a substantial amount of water to provide a flexible film having a uniformly irregular surface, and applying a coating of a hotmelt adhesive over the film, wherein the primer composition comprises an adhesive latex and an amount of ungelatinized granular starch effective to complex the latex water so that it is evaporated in a diffuse manner during the drying step. The layer of hot melt adhesive is not disturbed by the evaporation of residual water from the primer film. |
