Title: ITEM HAVING OPTIMIZED ADHESIVE PROPERTIES AND COMPRISING A SILICON ORGANIC LAYER
Abstract:
The invention relates to an item including a substrate having at least one main surface coated with an interference coating including: a layer A that has a refractive index less than or equal to 1.65 and is obtained via vacuum deposition assisted by an ion source made of at least one organosilicon compound A and making direct contact with said layer A, a layer B that has a refractive index greater than 1.65 and is obtained via vacuum deposition assisted by an ion source made of at least one metal oxide and at least one organosilicon compound B, said layer B containing at least one metal oxide having a refractive index greater than or equal to 1.8, or a layer C that includes a silicon oxide, has a thickness less than or equal to 15 nm, and makes direct contact with a layer E that includes at least one metal oxide having a refractive index greater than or equal to 1.8.
