Problems solved by technology

However, due to the limitations of the design and synthesis of resins (also known as oligomers), so far, under the premise of not adding solvents, such resins that can be cured quickly, have higher hardness or higher flexibility are often difficult to have lower Viscosity, which further restricts the formulation design and use, making it difficult for the traditional pure radical curing system to meet the above requirements

Abstract

The invention relates to the field of optical anti-counterfeiting, and discloses a protective ultraviolet light curing coating composition with 100% solid content and its coating and application, wherein, based on the total weight of the coating composition, the coating composition includes 58 ‑88wt% cationically curable component not containing hydroxyl groups, 5‑20wt% cationically curable component containing hydroxyl groups, 2‑12wt% free radical curable component, 1‑6wt% free radical curable Cured surface modification components, and a compound initiation system of 2-10wt% cationic initiator and free radical initiator; the coating composition has the characteristics of low viscosity and fast curing speed. The formed protective coating can significantly improve the chemical resistance, bending resistance, scratch resistance and stain resistance of optical anti-counterfeiting products, thereby prolonging the circulation life of optical anti-counterfeiting products.

Description

Technical field [0001] The present invention relates to an optical anti-counterfeiting element or an optical anti-counterfeiting product having the optical anti-counterfeiting element, in particular a 100% solid content, in particular a 100% solid content, a protective ultraviolet curable coating composition, and a coating thereof. Background technique [0002] In order to prevent the use of the forgery, banknotes, bank notes and other high-security or high value-of-value prints produced by scanning and copying, and have been widely used in optical anti-counterfeiting technologies, and very good results have been made. In banknote anti-counterfeiting, such optical anti-counterfeiting elements (such as holographic, dynamic light) often form an optical anti-counterfeiting product having specific optical features in a non-counterwell, anti-counterfeiting, anti-counterfeiting line, and plastic banknotes. However, during circulation, various disadvantages in the environment will deter...
