TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Adhesive: The polyurethane adhesive is an adhesive agent composition formed by adding 1-50 wt.pts of compound (A) with respect to 100 wt.pts of composition containing polyol (A) and crosslinking agent. Alternatively, the polyurethane adhesive is adhesive agent composition formed by adding 1-50 wt.pts of compound (A) with respect to 100 wt.pts of composition containing crosslinking agent and polyol (B, C, D, E or F). Preferred Compound: The compound (A) is chosen from carbodiimide compound, an oxazoline compound and epoxy compound. Preferred Composition: The polyol (A,F) is polyester polyol or polyester urethane polyol which has chain extension with an isocyanate compound having two or more functional groups. The polyol (B) is polycarbonate polyol or polycarbonate urethane polyol which has chain extension with isocyanate compound having two or more functional groups. The polyol (C) is an acryl polyol having hydroxyl group in its side chain. The polyol (D) contains 1-50 wt.% of polyol (A) and 50-99 wt.% polyol (B and C). The polyol (E) is a copolymerization type polyol which contains 1-50 wt.% of polyol (A) and 50-99 wt.% polyol (B and C).
