ABSTRACT:
The curable resin having a number average molecular weight of 600 to 6000 and at least two hydrolyzable silyl groups which is prepared by reacting an aliphatic polyester resin having acryloyl group and alcoholic hydroxyl group with an isocyanate silane compound: ##STR1## reacting the obtained reaction product with an aminosilane compound: ##STR2## and reacting the obtained reaction product with a monofunctional isocyanate: OCN-R.sup.5 and/or a polyfunctional isocyanate; and the composition containing the resin. The curable resin and the composition are excellent in acid resistance such as acid resin resistance, scratch resistance, solvent resistance, flexibility, and the like.
