AN ADHESIVE COMPOSITION, A PROCESS OF PRODUCING THE ADHESIVE COMPOSITION, A BONDING METHOD USING THE ADHESIVE COMPOSITION, AND A STRUCTURE HAVING THE ADHESIVE COMPOSITION APPLIED THERON
The present invention has for its object to provide an adhesive composition that is based on a naturally occurring material less likely to have adverse influences on the human body and has a tensile shear strength (adhesive strength) of at least 1 MPa with respect to a variety of adherends. The present invention provides an adhesive composition comprising at least a first pack and a second pack, wherein the first pack contains a tannic acid derivative in which a hydrogen atom in at least some hydroxyl group of tannic acid is substituted by a chain hydrocarbon group having at least one hydroxyl group, and the second pack contains a hydrocarbon having at least two cyanate groups or a derivative of the hydrocarbon.
