<P>PROBLEM TO BE SOLVED: To provide an adhesive composition, which is used as an adhesive agent for optical parts without including an organic solvent in consideration of environmental conservation and safety and satisfies durability, peelability and stress relaxation characteristics required for optical purposes. <P>SOLUTION: The preparation process of an adhesive composition of a dispersed aqueous type for optical parts comprises the steps of: polymerizing 100-1,500 pts.wt. of monomers containing an alkyl (meth)acrylate as a major component of an acrylate component based on 100 pts.wt. of a urethane component in an aqueous dispersion of the urethane component without sustantially containing an emulsifier to form a polymer containing 30-80 wt.% of a solvent-insoluble portion comprising the urethane component and the acrylic component; and incorporating 100pts.wt. of the above prepared polymer with 0.01-1 pt.wt. of a silane coupling agent. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
