A recently granted patent (Publication Number: US11926747B2) discloses an innovative ink formulation designed for use in security applications. The ink comprises a transparent matrix that is both UV curable and heat sealable, along with at least one pigment component. When cured under UV light, the ink exhibits a peel strength ranging from 6 to 8 N/cm, allowing it to act as a hot glue when subjected to pressure and heat during a lamination step. The matrix, which can be cured within a UV wavelength window of 320 to 420 nm, is composed of materials such as polyurethane or acrylate polymer, while the pigment component includes goniochromatic metal particles, typically platelet-shaped and oriented flat within the matrix.

The patented ink is intended for use in creating safety structures like passports, identity cards, and banknotes, where security features are crucial. By incorporating the UV-cured ink into a semitransparent layer of these structures, enhanced protection against counterfeiting and tampering can be achieved. The method for utilizing the ink involves silkscreen printing it onto a polymeric material surface, offering a versatile and efficient way to integrate the security features into various products. With the ability to achieve adhesiveness through lamination under pressure and heat, this ink formulation represents a significant advancement in the field of security printing and anti-counterfeiting measures.
