摘要: Disclosed is a process for the production of a photochromic object, composed of a polymer and containing at least one spirooxazin compound, having the following process steps: an acrylate monomer or a methacrylate monomer, respectively a mixture of a multiple thereof is utilized as the polymerizable monomer, the photochromic dyes as well as a polymerization initiator are mixed in the polymerizable monomer, the mixture yielded thereby is placed in a casting mold, polymerized and hardened. The present invention is distinguished by, in order to obtain a neutral gray, neutral brown or green photochromic tint of the polymerizable mixture, several photochromic dyes being added of which at least one is not a spirooxazin, and by the concentration of the spirooxazin compound(s) amounting to no more than 0.045 weight percent relative to the mass of the utilized monomer, and that of the polymerization initiator(s) amounting to more than 1 weight percent relative to the mass of the utilized monomer.

摘要: A high refractive index, curable, synthetic resin composition comprising a core resin composition composed of a mixture of ethylenically unsaturated compounds, and an initiation system containing both photo and thermal initiators, particularly a photochromic resin composition which further includes at least one photochromic dye. Also a curing process, which includes a combination of multi-step radiation curing and thermal annealing. Articles produced of cured composition exhibit superior physical and, in appropriate cases, photochromic properties and can be easily mass produced on a commercial scale due to short processing time and use of readily available chemicals.

摘要: A photochromic compound suitable for use as a single substance for photochromic tinting of a transparent plastic article so that the tinted article has a neutral gray or brown color in the excited state, is made by fusing at least two non-identical photochromic sections to an aromatic structure. The photochromic sections are selected so that the different absorption wavelengths of the excited photochromic sections give rise to a neutral gray or brown color in the plastic material and are selected from the group consisting of oxazines and pyrans. At least one of the photochromic sections is not an indolino spiropyran. The aromatic structure to which the photochromic sections are fused is selected from the group consisting of benzene, biphenyl, naphthalene, anthracene and phenanthrene. The positions of fusion of the photochromic sections on the aromatic structure are directly adjacent to the oxygen atom of the pyran or the oxygen or nitrogen atom of the oxazine.
