<p>The network made of crossed interwoven wires for constitution of a light attenuating screen and for forming an openworked grid with determined opening factor (5% or 3%). The interwoven wires are coated with a composition (5-15% m/m) having a polymeric binder (4-14% m/m) and an organic photochromic pigment (0.09-0.3% m/m). The photochromic organic pigment comprises Photosol(RTM: Photochromic dye), Variacrol(RTM: Photochromic dye) or Reversacol(RTM: Photochromic dye). The network made of crossed interwoven wires for constitution of a light attenuating screen and for forming an openworked grid with determined opening factor (5% or 3%). The interwoven wires are coated with a composition (5-15% m/m) having a polymeric binder (4-14% m/m) and an organic photochromic pigment (0.09-0.3% m/m). The photochromic organic pigment comprises Photosol(RTM: Photochromic dye), Variacrol(RTM: Photochromic dye) or Reversacol(RTM: Photochromic dye). The polymeric binder has a flexibility characterized by an elongation at break measured according to standard DIN 53504 >= 600%. The composition comprises an anti-ultraviolet stabilizing agent (0.09-0.3% m/m) and antioxidative agent (0.2-1% m/m). The interwoven wires are associated by weaving, and are made of glass. Independent claims are included for: (1) a screen or curtain; and (2) a process of fabricating a network.</p> |
