  • Method for dyeing a transparent article made of a polymeric substrate with gradient tint
    Patent number: 10201944
    Abstract: A method for dyeing a transparent article made of a polymeric substrate with gradient tint comprising: a) a first step of photodegrading the polymeric substrate (1) of the transparent article, by irradiation (3) of at least one first surface of the article to UV radiations to produce a gradiently photodegraded surface layer of the polymeric substrate, and b) a second step of dyeing said first face of the article with a dyeing agent so as to diffuse said dyeing agent into the gradiently photodegraded surface layer of the polymeric substrate.
