Beschreibung
Zusammenfassung:	The present disclosure relates to a color-changing composition comprising: a) a dye selected from the group consisting of metal complexes, wherein the metal complexes comprise: i. a central ion of a metal selected from the group consisting of iron, vanadium, chromium, manganese, cobalt, nickel and copper; and ii. chelate ligands having heteroaromatic structures; b) an adhesive composition; c) optionally, a curable polymer resin selected from the group consisting of epoxy resins, polyester resins, polyurethane resins, vinyl resins, and any combinations or mixtures thereof; wherein the color-changing composition has an initial color and is capable of changing color to a final color upon contacting a curable composition comprising one or more curing agents and a curable polymer resin; wherein the one or more curing agents are suitable to cure the curable polymer resin; and wherein the initial color is different from the final color.
