Urethane resin composition, and moisture-permeable film |
abstract |
The problem which this invention is going to solve is providing the urethane resin composition excellent in moisture permeability and film strength using a biomass raw material. The present invention is a urethane resin composition comprising a polyol (A) containing a polyol (a1) having an oxyethylene group, and a urethane resin (X) containing polyisocyanate (B) as essential raw materials, wherein the polyol (A) This biomass-derived glycol (i) and crystalline polybasic acid (ii) further contain polyester polyol (a2) as raw materials, and the hydroxyl equivalent of the polyol (A) is in the range of 400 to 600 g/eq. It is to provide a urethane resin composition, characterized in that. Further, the present invention provides a moisture-permeable film formed of the urethane resin composition. |
