Discoloration of Historical Plastic Objects: New Insight into the Degradation of β -Naphthol Pigment Lakes

Light is a determining factor in the discoloration of plastics, and photodegradation processes can affect the molecular structures of both the polymer and colorants. Limited studies focused on the discoloration of heritage plastics in conservation science. This work investigated the discoloration of...
