Multilayer body

Abstract

Provided is a multilayer body having good print readability and removability. A multilayer body (1) is for a laser marking label and includes a first layer (10) allowing laser light to pass through, a second layer (20) developing a color by laser light, and a third layer (30) having adhesiveness, which are stacked in this order. The second layer (20) consists of a resin composition containing an acrylic-based copolymer, an isocyanate-based crosslinking agent, a color development pigment, and a white pigment. The isocyanate-based crosslinking agent is selected from (i) an aromatic-aliphatic isocyanate-based crosslinking agent or (ii) a mixture of an aliphatic or alicyclic isocyanate-based crosslinking agent and an aromatic isocyanate-based crosslinking agent. A contained amount of the isocyanate-based crosslinking agent is 5-40 parts by mass with respect to 100 parts by mass of the acrylic-based copolymer. The second layer (20) is in contact with the first laver (10).
