| abstract |
The invention relates to an amorphous, structured, transparently-coloured, UV-light absorbing film made from a crystallisable thermoplastic, the thickness of which lies in the range from 30 to 1000 mu m and a method for the production and use thereof. The film contains at least one dyestuff and one UV-absorber, both of which are soluble in the thermoplastic and is characterised by good optical properties, a high light transmission in the wavelength range >/= 400 nm, preferably 420 800 nm, an economical thermoformability and the absorption of short wave UV-light in the wavelength range = 380 nm. |
