Abstract
A polyol composition includes a first polyol (A-I) having a number average molecular weight of 1000 to 10000; and 35 to 60% by weight of a core-shell polymer (B) including a core layer and a shell layer. The core-shell polymer is uniformly dispersed in the first polyol (A-I) and has a volume average particle diameter of 0.01 to 0.6 μm. A polymer constituting the shell layer has a solubility parameter of 9.30 to 10.20 (cal/cm)and comprises at least 25 to 90% by weight of an alkyl (meth)acrylate unit having a linear or branched alkyl group of 4 to 10 carbons.
