The purpose of the present invention is to improve surface scratch problems occurring in the manufacturing process and handling of an adherend on which stamping foil is applied, prevent a problem in which a transfer layer of stamping foil is separated at a portion that is bent when the adherend is folded, secure binding force in printing with various inks, and fundamentally prevent powder generated during cutting according to a product standard in a stamping foil manufacturing process. To this end, the stamping foil of the present invention comprises: (a) a base film which is removed after stamping transfer; (b-1) a wear-resistant release layer formed on the base film and containing a polyurethane-based release agent, an acrylic resin, and an ethene-based polymer additive, or (b-2) (i) a polyurethane-based release layer formed on the base film and (ii) a wear-resistant layer formed on the polyurethane-based release layer and containing an acrylic matrix resin and an ethene-based polymer additive; (c) a moisture penetration-preventing and metal-deposited heat-resistant cured coating layer; (d) a metal deposition layer formed on the moisture penetration-preventing cured coating layer; and (e) optionally, a thick film protective layer formed on the metal deposition layer, for preventing the corrosion of the metal deposition layer.

A nonwoven mat and a method of making a nonwoven mat are provided. The nonwoven mat includes reinforcing fibers and a binder composition that includes a polycarboxy polymer and polymer microspheres. The binder composition may also include low-density fibers, such as microfibrillated cellulose fibers. The polymer microspheres have a thermoplastic shell that encapsulates a blowing agent. The thermoplastic shell has magnesium hydroxide on its outer surface. The components of the binder composition interact with one another and/or the reinforcing fibers to form a nonwoven mat having a less permeable structure and a higher caliper.
