PROBLEM TO BE SOLVED: To provide an outer wall material capable of improving weatherability, and capable of also improving an antifouling property, by restraining the thermal deterioration in an inkjet printing layer, without confining heat on the inside.SOLUTION: An outer wall material comprises a base material 1, a light-colored coating layer 3 formed in the base material 1, an inkjet printing layer 4 formed in the light-colored coating layer 3, a heat-ray shielding layer 6 formed in the inkjet printing layer 4 and a functional layer 7 formed in the heat-ray shielding layer 6. The inkjet printing layer 4 is formed by inkjet printing. The heat-ray shielding layer 6 is constituted so as to transmit a visible light ray and also to reflect or absorb an infrared ray. The functional layer 7 is constituted so as to transmit the visible light ray and also to have hydrophilicity or water repellency. |
