Original Abstract
The principle of the self-adhesive printed foil with antiviral and antimicrobial function is a combination of organic biocides and special photosensitive substances that use light energy to produce reactive oxygen species. The key component in this printed layer is zinc phthalocyanine, a substance activated by sunlight or visible light in the 600 to 700 nm. Zinc phthalocyanine absorbs light, causing it to be excited to the triplet state. In the excited triplet state, phthalocyanine interacts with molecular oxygen. This interaction leads to quenching of the triplet state of phthalocyanine and energy transfer to the oxygen molecules. The transfer of energy to oxygen leads to the formation of singlet oxygen, a powerful oxidizing agent that destroys viruses and bacteria.
