The present invention relates to an adhesive composition including organic silicon compound shown as below chemical formula 2. <chemical formula 2> R refers to a hydrolytic group, R′ refers to an alkyl group having one or more than one carbon and no more than four carbon. A refers to a straight-chain or branched-chain alkyl group having one or more than one carbon and no more than six carbon. X refers to an atom of oxygen or sulfur. Z refers to any one among NH-, oxygen or sulfur. M refers to any one among NH-, oxygen or sulfur. R4 through R7 respectively and independently refer to one among alkyl, alcoxy, fluoroalkyl or amino groups having one or more than one carbon and no more than six carbon. In this case, R5 and R6 can be directly bonded to form a double bond between the carbon atoms, where the above functional groups are bonded. Also, R4 and R7 can be used to form either an aliphatic or aromatic ring structure along with the carbon atoms in bond. Integer m ranges from one to three, while integer n ranges from zero to three. The organic silicon compound of the present invention contains an organic functional group having high coordination capability against an active proton such as hydroxyl group. The adhesive compound comprising the same is used to form hydrogen bonds between the active protons located on the side chains of base polymer and functional groups of silane coupling agent. As a result, reworking properties at initial state is excellent, and long-term durability is also excellent since adhesive force tend to increase at high temperature or at both high temperature and moisture. |
