 Fluorescent whitening agent is a kind of colorless, special powder, organic matter can absorb ultraviolet wavelength of 300 nm, which absorbs 300-400 nm uv light wave, and will absorb the energy conversion, and the radiation under 500 nm visible light (blue or purple fluorescent). When objects do not reflect purple light, colour and lustre is yellow. If join the fluorescent whitening agent, and expose it to the more than 300 nm under uv light, can emit visible fluorescent purple, this is not reflected in the matrix can make up for blue or purple wavelength to hide the yellow visible light waves. That adding a small amount of blue color and white product is expected to achieve the principle of "cover yellow" different, fluorescent whitening agent is increase the amount of light reflection or transmission plays a role of "light", and plus "reduced" light blue tooth whitening effect is different, so that the products surface brightness enhancement. When the "light" strong, can make the reflectivity considerably more than 100%.
