    摘要: Provided are: an outdoor urethane adhesive agent which has excellent initial adhesion properties, exhibits excellent adhesion properties after being cured, can be cured into a coating film having excellent flexibility, and preferably has superior weather resistance; a solar cell back sheet which is produced using the adhesive agent; and a solar cell module which is produced using the solar cell back sheet. An outdoor urethane adhesive agent (A) comprising a urethane resin (A) produced by the reaction of an isocyanate compound (a1) with a polyol (a2) having an ester bond, wherein the isocyanate compound (a1) comprises at least one compound selected from aliphatic isocyanates and alicyclic isocyanates, and the polyol (a2) comprises both a polyester polyol (a2-1) and an acrylic polyol (a2-2). The adhesive agent has excellent initial adhesion properties, exhibits excellent adhesion properties after being cured, and can be cured into a coating film. having excellent flexibility. When the adhesive agent additionally contains a hydroxyphenyltriazine-type compound, the adhesive agent can rarely undergo the change in color and can have superior weather resistance.
