Abstract:
1. An adhesive composition comprising a polyisocyanate component and a polyol component, wherein the polyol component includes polyester polyamide polyol and/or polyurethane polyester polyamide polyol, the polyester polyamide polyol comprises a polyester unit formed by reaction between polybasic acid and/or alkylester thereof and polyol, and a polyamide unit which comprises an amide bond formed by reaction between dimer acid and polyamine as an essential component; wherein said polyamide unit is formed by reaction between polybasic acid and polyamine, the polyurethane polyester polyamide polyol is formed by reaction between the polyester polyamide polyol and polyisocyanate, and wherein an elution test using gas chromatograph-flame ionization shows the concentration of a cyclic compound, formed during the formation of said polyester unit and said polyamide unit, is 0.5 ppb or less based on a dibutyl phthalate standard in a solution eluted from 0.5 mL/cm
