摘要: An optically transparent photochromic plastic material is described which is comprised of materials with a sulphur content and which via polymerization processes contains photochromic organic compounds as solid ingredients, which possess at least two ring systems linked via carbon atom and whose photochromic tint is based on a reversible bond rupture to the spiro-C atom.
