This type of paper is offered under the trademark YOU’RE SAFETM and uses as security feature the chemical protection. Shortly, when such paper comes into contact with a chemical substance, on that place appears an irreversibly spot of colour that reveals the fraud or counterfeiting attempt. Ceprohart provides papers with protection against over 70 different chemicals.
Chemical protection can be:
– chemical protection against acids
– chemical protection against bases
– chemical protection against oxidizing (bleach)
– chemical protection against organic solvents
– chemical protection against potassium permanganate
A security paper can present chemical protection to one or more chemical agents and it can be produced in combination with any other security features depending on customer needs.
Applications
It is used for documents where counterfeiting is usually made by modifying the existing text, or documents which authenticity can be immediately verified (checks, bank payment documents, etc.). Basically, when it is trying to erase by chemical means a text from a secured document, an irreversible colour spot occurs on the test site that downgrades the document.
Instruments and verification techniques
Chemical protection verification kit – is used to test the chemical protection paper. The substance, either oxidizer, acid, base or solvent, applied on the chemical protection paper surface will irreversibly colour it.
