Abstract

"COMPOSTO NAFTOPIRâNICO E ARTIGO FOTOCRÈMICO". São descritos novos compostos reversíveis fotocrómicos de 2H-naftol[1,2-b]pirano, exemplos dos quais são compostos tendo certos substituintes no átomo de carbono de número 5 da porção nafto do naftopirâno e na posição 2 do anel de pirano. Certos substituintes podem também estar presentes nos átomos de carbono de número 6, 7, 8, 9 ou 10 da porção nafto do naftopirano. Também descritos estão materiais hospedeiros orgânicos que contêm ou que são revestidos com tais compostos. Artigos tais como lentes oftálmicas ou outras transparências plásticas que incorporam os novos compostos naftopirânicos ou combinações destes com compostos fotocrómicos complementares, p. e., compostos do tipo espiro(indolina), também são descritos.
