A laminate including a substrate, an antibacterial agent-containing layer on a surface of the substrate, and a moisture triggering layer on the antibacterial agent-containing layer is provided, wherein the antibacterial agent-containing layer contains a volatile antibacterial agent, and the moisture triggering layer contains a hydrophilic polymer such as polyvinylpyrrolidone. The laminate releases a relatively large amount of gaseous anti-bacterial agent in a humid environment in comparison with a dry environment.一種包含一基材,位於該基材的一表面上的含抗菌劑層,及位於該含抗菌劑層上的一濕度啟動層的積層產品被揭示,其中該含抗菌劑層含有一揮發性的抗菌劑,該濕度啟動層含有一親水性高分子(例如聚乙烯吡咯烷酮)。該積層產品於高濕度環境下相對於乾燥環境下會釋放出較大量的氣態該揮發性的抗菌劑。
