Abstract (en)
[origin: WO2012041945A1] The invention pertains to a method for detecting and measuring the permeation of a fluid through a layer having a first surface (S1) and a second surface (S2), wherein said fluid is contacted with said first surface (S1) and wherein a coating composition comprising a reactive dye is applied to said second surface (S2) to yield a reactive dye coating onto said surface (S2), wherein said reactive dye coating undergoes a colour change when contacted with said fluid, said method comprising: - obtaining an image of at least a portion of said second surface (S2); - applying RGB colour model to said image to determine the red (R ), green (G) and blue (B) coordinates of at least one point of said image; - comparing RGB coordinates of said point to the RGB coordinates of a reference colour; and - correlating said comparison to the concentration of permeating fluid on the surface (S2).
