Layer A can include an aliphatic polyester selected from polyhydroxyalkanoate, poly(lactic acid), polycaprolactone, copolyesters and polyesteramides. Layer A can include a polyolefin. Layer A can include a co- or ter-polymer that includes ethylene or styrene monomer, an unsaturated anhydride-containing monomer, epoxide-containing monomer, or carboxylic acid-containing monomer, and a (meth)acrylic ester monomer. Layer B can include a polyolefin and a polyester. Layer B can include a co- or ter-polymer that includes an ethylene or a styrene monomer, an unsaturated anhydride-containing monomer, epoxide-containing monomer, or carboxylic acid-containing monomer, and a (meth)acrylic ester monomer.

A composite material combininga precious metal or an alloy containing a precious metaland a boron-based ceramic having a melting point greater than that of said precious metal and a density at most equal to 4 g/cm3.

A selective dyeing method is used for dyeing a substrate, selectively within a first exposed surface portion of said substrate. For this purpose, the substrate consists of a material that is impervious to a dye with the exception of the first portion of the exposed surface. In particular, the impervious material can form a layer which covers a base portion of the substrate in a second portion of the exposed surface. The substrate is heated such that the dye penetrates a pervious material which constitutes the first portion of the exposed surface. The method is particularly useful for eliminating light diffused by the walls of a multilayer structure which is supported by means of ocular glass.
