发明名称 Weather-resistant adhesive composition
摘要 The present invention is to provide a weather-resistant adhesive which achieves adhesive property, moist heat resistance and weather resistance in a practical level by means of aging at low temperature and for short time. There is provided a weather-resistant adhesive composition, characterized in containing (A) a polyester polyol having an acid value of 30 to 150 equivalents/106 g and (B) a polyisocyanate compound comprising an aliphatic polyisocyanate compound and/or an alicyclic polyisocyanate compound. Also, there is provided a layered product, characterized in being prepared by laminating films using said composition.
