Abstract
A hot-melt web has a buffer adhesive layer of a thermosetting resin on a light transmissive, heat resistant resin support. The hot-melt web has the advantages of light transparency, heat resistance, weather resistance, controlled entrainment of bubbles and easy removal of bubbles during thermocompression bonding, provides a sufficient bonding force, and effectively corrects random deformations of a module sheet. The hot-melt web is suitable for use in the bonding, joining and laminating steps in the manufacture of optical discs such as DVD and flat panel displays, is easy to eliminate bubbles, and is effective for improving the quality of an associated product. A laminate using the hot-melt web and a method for preparing the laminate are also provided.
