Polyester-based masking sheet |
abstract |
The present invention relates to a polyester-based masking sheet including: a substrate; and a pressure-sensitive adhesive layer provided on the substrate, which contains a polyester resin obtained by condensation-polymerizing a plant-derived dicarboxylic acid with a plant-derived diol in a ratio such that a content of hydroxyl group in the diol is from 1.01 to 1.40 mol per 1.00 mol of carboxyl group contained in the dicarboxylic acid, and a tackifier in an amount of from 10 to 50 parts by weight per 100 parts by weight of the polyester resin, and is crosslinked by a crosslinking agent to have a gel fraction of 40 to 90%. |
