1. Optical variable pigment can be used for Security material?
Yes. Our Optical variable Pigment has quite complicated manufacturing process. Many high technology fields are involved
in our manufacturing line, such as fine chemicals, ultrafine pulverization, optical technology, vacuum coating technology, and nano-
technology.
So our pigments are also often used to High technology application fields, such as Currency, Passport, ID card, Tax Stamp, Certificates,
and Cheques, etc. Some packagings of Tobacco, alcohol, agricultural products also need our Pigment to do the anti-fake printings.
