<p><P>PROBLEM TO BE SOLVED: To provide a rear surface protective sheet for a solar cell module at low cost by using a method of forming a weatherproof coating layer on an outermost layer thereof, the rear surface protective sheet having a colored appearance such as white color and including excellent weatherproofness. <P>SOLUTION: In a rear surface protective sheet 6 for a solar cell module, a coating layer 61 formed on a base material layer 60 of the rear surface protective sheet 6 is formed by sequentially laminating an intermediate coating layer 611 excellent in adhesiveness with a base material layer resin and an outermost coating layer 612 specifically excellent in solvent resistance and weatherproofness. The coating layer is manufactured by optimizing an NCO amount and a hydroxyl value of each layer within a region which is different for each layer. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
