- the present invention relates to a coating composition that can provide protection from exposure to ultra violet (“UV”) light or UV and visible light having wavelengths from less than 200nm and up to 500 or 550 run.
- UV ultra violet
- the present invention relates to a coating composition that can be applied to containers that are used for storage of products that are light sensitive.
- products include, but are not limited to, foods, beverages, and pharmaceuticals.
- Uncoloured clear containers are known to fail to protect light sensitive contents of the containers from the deleterious effect of UV light or UV and visible light.
- Fully opaque or deep amber coloured containers are less attractive than clear containers in situations where consumers wish to see and inspect the contents of the containers .
- a particular deleterious effect of UV and visible light on beverages such as beer or wine is the generation of off-flavours called "lightstrike” .
- the human nose is particularly sensitive to such off-flavours and therefore the use of containers with UV and visible light protection is important for such products.
- hops that are chemically modified so as to remove the chemical precursor of the molecules responsible for the off-flavours .
- these molecules are also the chemicals that contribute to the bitter flavour that is sought by beer drinkers.
- the resulting beer is considerably less attractive to many consumers .
- metal oxides can strongly absorb in the UV and visible regions of the light spectra.
- metal oxides have lacked the clarity and the transparency to be suitable for use as additives for coatings to be applied to containers where it is important to be able to view the contents of the containers.

- the pigment further includes nanoparticles of blue or green pigments that cause the coating composition to be a transparent blue or green colour.
- the pigment includes nanoparticles of yellow or red iron oxide absorber pigments and blue or green pigments that cause the coating composition surprisingly to be a transparent blue or green colour.
