Abstract:
An adhesive composition comprising:(a) a polymerizable (meth)acrylate compound having a phosphate group,(b) a thiol compound selected from the group consisting thiol compounds containing a silicon atom and isocyanuric acid compounds having a R'--SH group bonded to each of the three nitrogen atoms thereof,(c) a polymerizable compound having a double bond and having no phosphate group, and(d) a photopolymerization initiators,wherein said thiol compound (b) is present in an amount so that the molar ratio of the mercapto group or groups contained in the thiol compound (b) to the hydroxyl group or groups of the phosphate group or groups of said polymerizable (meth)acrylate compound (a) is in the range of 0.3:1 to 10:1, andwherein said polymerizable (meth)acrylate compound (a) is present in an amount of 0.1-5% by weight based on the total weight of said polymerizable (meth)acrylate compound (a) and said polymerizable compound (c).
