Embodiment 1-4
[0259] Examples 1-4 were carried out on substrate 1 as 0.5 μl droplets on partially overlapping lines using a contact angle dispenser (Dataphysics OCA 50, DataPhysics Instruments GmbH, Germany). The center of the applied droplet was about 1-2 mm (over a distance of about 1 cm). The prepared samples were examined by SEM imaging.
Embodiment 1
[0260] Example 1 (comparison)
[0261] Substrate 1 was treated with Treatment Composition A. No water-insoluble pattern formation was detected by SEM imaging (see figure 1 ).
Embodiment 2
[0262] Example 2 (comparison)
[0263] Substrate 1 was treated with Treatment Composition B. No water-insoluble pattern formation was detected by SEM imaging (see figure 2 ).

Abstract
The present invention relates to a method for producing a water-insoluble pattern on and / or in a substrate, a substrate obtainable by said method, a product comprising said substrate and the use of said substrate in different applications.
Description
technical field [0001] The present invention relates to a method of producing a water-insoluble pattern on and / or in a substrate, a substrate obtainable by said method, a product comprising said substrate and the use of this substrate in different applications. Background technique [0002] Logos, imprints or identifying images are used in a wide variety of products in visible or hidden form for marking, identification or anti-counterfeiting purposes. [0003] The possibility of producing more complex patterns or images with modern printing and coating technologies that have become more accessible and affordable in recent years has created a need for unusual and unique patterns for commercial applications, advertising and branding Increasing. However, rapid advances in printing and coating technologies have also paved the way for potentially easier counterfeiting or duplication of brands, products, banknotes, and more. [0004] Furthermore, in recent years, advances in mic...
