Abstract
The purpose of the present invention is to provide a hot-melt adhesive sheet for a stacked polishing pad wherein a polishing layer is resistant to detachment from a support layer even when high temperatures are produced by long periods of polishing. This hot-melt adhesive sheet is used to laminate a polishing layer to a support layer, and the hot-melt adhesive is a polyester-based hot-melt adhesive that, for each 100 weight parts of a polyester-resin base polymer, contains 2 to 10 weight parts of an epoxy resin that has at least two glycidyl groups per molecule.
