ABSTRACT:
The instant invention pertains to a curable resin composition comprised of A) 100 parts by weight curable resin, and B) 0.1-500 parts by weight of an organopolysiloxane having organic groups that contain epoxy groups, which is expressed by the formula: ##STR1## wherein R.sup.1 is a univalent hydrocarbon group excluding alkenyl groups, R.sup.2 is a hydrogen atom or a univalent hydrocarbon group excluding alkenyl groups, R.sup.3 is an alkoxysilylalkyl group or an organic group that contains epoxy groups, a is 0 or a positive integer, b is a positive integer and c is a positive integer, where a/c has the value of 0 to 4, b/c has the value of 0.05 to 4 and (a+b)/c has the value of 0.2 to 4. The curable resin composition of the instant invention has superior flowability that produces a hardened resin with superior flexibility and adhesion.
