摘要：Provided are a polyester polyol which exhibits a high adhesion strength after being cured in a case of being used as a main agent for an adhesive for lamination, an excellent temporal stability in which the adhesion strength is not deteriorated in a heat and moisture resistance test, and an excellent appearance after being subjected to a lamination processing, a resin composition using the same, a two-part adhesive for lamination which contains the resin composition, and a back sheet for a solar cell. Specifically, as a main agent for the two-part adhesive for lamination, a polyester polyol which has a resin structure obtained by reacting a branched alkylene diol, a long-chain aliphatic dicarboxylic acid having 8 to 20 carbon atoms, and an aromatic tricarboxylic acid, and has a weight average molecular weight (Mw) of 10,000 to 100,000 and a molecular weight distribution (Mw/Mn) of 3.0 to 4.7 is used.
