ABSTRACT:
A pressure-sensitive adhesive composition comprises, as pressure-sensitive adhesive components thereof, an acrylic-based polymer and a silane compound having at least two alkoxysilyl groups in its molecular. The silane compound is a compound which is represented by the following general formula (I).
[General Formula (I)] ##STR1## (In this general formula, "A" is a group having a chain structure and/or a ring structure containing 1 to 12 carbon atom(s), R.sub.1 and R.sub.4 are respectively an alkyl group containing 1 to 5 carbon atom(s), and R.sub.2, R.sub.3, R.sub.5 and R.sub.6 are respectively an alkyl group or alkoxyl group containing 1 to 5 carbon atom(s).)
The amount of the silane compound to be contained is preferably 0.001 to 10 parts by weight with respect to the pressure-sensitive adhesive composition of 100 parts by weight. Thus formed pressure-sensitive adhesive composition can sufficiently and effectively relieve a stress concentration which is caused by shrinkage of the base material under the high temperature and high moisture condition.
