Organic substrate provided with a light absorptive antireflection film and process for its production
First Claim
1. An organic substrate provided with a light absorptive antireflection film, which comprises an organic substrate, and a light absorbing film and a low refractive index film formed in this order on the substrate, to reduce reflection of incident light from the low refractive index film side, wherein the organic substrate has a plasma-treated surface, and a layer made essentially of at least one member selected from the group consisting of silicon, a silicon nitride, a silicon oxide and a silicon oxy-nitride, is formed between the plasma-treated substrate surface and the light absorbing film.
