Abstract

DC60 (08/12/43) described as a photochromic compound. 2H-Naphtho [1,2-b] Piran New species with important characteristics With two adjacent groups that can be modulated with A group that gives the electrons that Forces at positions 8 and 9 or heterocyclic fuse groups produced by the combined displacement group Which is soft enough to moderate The group gave the electron at position 2 and gave a rate of at least 80 in the relative delta OD at the Saturation test The compounds also have a fixed group at position 5 and, by option, at position 6, of the naphtho compound part. May be represented by the following graphic structural formulas (chemical formulas) are also described as organic polymer materials that are composite or coated with these compounds. By choice of things Transparent visible matter, such as optical lenses or other plastic translucent materials that are compatible with new naphthopyran compounds, or the combination of them with photochromic compounds such as other naphthopyran. Of course, benzopyran and spirulina (Indo Line) compounds are also described.
