<p>The present invention provides phenolic resin-based adhesives which do not produce waste water and industrial wastes and which have good adhesive force, especially after being exposed to thermal history. That is, the present invention provides a phenolic resin-based adhesive composition which contains a polyvinyl butyral, a novolak type phenolic resin or a novolak type phenolic resin and a resol type phenolic resin, and hexamethylenetetramine and which is obtained by uniformly melt-mixing these components, or a phenolic resin-based adhesive composition which contains a polyvinyl butyral, an epoxy resin, a novolak type phenolic resin or a novolak type phenolic resin and a resol type phenolic resin, and hexamethylenetetramine and which is obtained by uniformly melt-mixing these components.</p> |
