| 摘要 |
A UV screening composition is disclosed which comprises an effect coated particulate material having a substantially rutile crystal habit and an average particle size greater than or equal to 0.5 pm dispersed in a medium at a concentration within a range of 1% by volume to 40% by volume, based on the total volume of composition. The composition may be coloured or non-coloured and applied onto one or more surfaces of a substrate to provide UV light protection without also increasing UV light activated photocatalytic effects which are observed for some titanium dioxide compositions. |
