An invisible photonic crystal (PC) pattern encrypted at the dry state and decrypted by solvent is a new anticounterfeiting material system. but its diversity and complexity in response are still required to be increased to enhance the anticounterfeiting effect. Herein. a triple‐state invisible pattern encrypted in hollow‐silica/polyurethane (h‐SiO2/PU) film with two decryption mechani... https://parlorcityfurniturers.shop/product-category/workstation/
