Abstract
Abstract A laminated product comprising substrate (7) and a thin layer (11, 12) of a dielectric compound formed from the oxide or the suboxide of gallium antimonide or indium antimonide, an optical information carrier containing such a thin layer, whereby said thin layer, dependent upon the oxygen content, may function as a recording layer 11 or as a transparent distance layer 12, as well as the suboxide of gallium antimonide or indium antimonide used in the laminated product.
