The base material protective layer is a raw material cured article containing a polyester resin or an acrylic resin, and a curing agent. The polyester resin or the acrylic resin has a reactive group that reacts with the curing agent in a terminal or a side chain, or in both. The curing agent contains an isocyanate other than an alicyclic isocyanate, and an alicyclic isocyanate, and the ratio of the weight [a] of the isocyanate other than the alicyclic isocyanate to the weight [b] of the alicyclic isocyanate ([a]/[b]) is 99/1-80/20. |
