Abstract
In the construction of a hard cover book or in the hinge application of a soft book cover or another graphic arts construction of this invention can be manufactured more efficiently with substantial resistance to cold flow or creep through the use of a single adhesive. The adhesive of choice for this application has an enhanced resistance to cold flow or creep, sufficiently high bond strength, and a viscosity that is controllable through a temperature range permitting it to be used for a variety of graphic arts construction applications.
