A laminate including at least a heat-sensitive adhesive layer, a substrate layer, and a protective layer in this order, wherein the substrate layer has a thermoplastic resin film, the heat-sensitive adhesive layer contains a higher fatty acid amide, and the protective layer contains a silicone-based release agent. An in-mold label comprising this laminate. A molded body obtained by affixing this in-mold label. An in-mold label in the form of a roll obtained by winding this in-mold label. This invention provides an in-mold label that is less susceptible to dirt and scratches, excellent in decorativeness and visibility, less likely to cause friction when the labels are stacked on each other, and easy to handle, and has strong adhesive strength to a molded body.

Laminate, in-mold label, labeled molded body, rolled in-mold label, and stacked in-mold labels

A heat-sensitive label that can achieve both sufficient adhesive strength and high recyclability is provided. A heat-sensitive label comprising a substrate layer and a heat sealing layer (A) on the substrate layer, wherein the heat sealing layer (A) comprises a heat sealing resin and a carboxylic anhydride-modified polyolefin resin (h); and a product MCh of an acid value M (mgKOH/g) of the carboxylic anhydride-modified polyolefin resin (h) and a content Ch (% by mass) of the carboxylic anhydride-modified polyolefin resin (h) in the heat sealing layer (A) is 1.5 to 6.0.
