WEATHER-RESISTANT FILM FOR THE YELLOW COLORATION OF RETRO-REFLECTIVE MOULDED BODIES

The invention relates to a film, comprising at least one PMMA layer that has been coloured using a yellow anthraquinone dye. According to the invention, the PMMA layer comprises colour co-ordinates (x;y) that lie within the ranges 0.4 = x = 0.54 and 0.44 = y = 0.54, as defined according to the CIE 1...

More Information
Summary:The invention relates to a film, comprising at least one PMMA layer that has been coloured using a yellow anthraquinone dye. According to the invention, the PMMA layer comprises colour co-ordinates (x;y) that lie within the ranges 0.4 = x = 0.54 and 0.44 = y = 0.54, as defined according to the CIE 1931 Standard Colorimetric System. The concentration of the yellow dye of the PMMA layer is at least 3 wt. %, in relation to the total weight of the PMMA layer.
