3D-GRAM® CONTRUST Security Patch for the 100/50 Nobelists House Note

3D-GRAM® CONTRUST is the newest photopolymer feature in the KRYPTEN 3D-GRAM® series. 3D-GRAM® CONTRUST is a photopolymer security patch with a colour-changing effect. When the element is rotated by 180°, the colour of the images switches from red to green and vice versa. Such dynamic colour-changing effect captivates the public while an unambiguous colour contrast leaves no doubt about the banknote authenticity.


3D-GRAM® CONTRUST security patch is the outcome of intensive work by KRYPTEN R&D team to create innovative photopolymer-based security features. This is a striking and catchy element with an incredibly simple and unambiguous identification. Realistic images, pure colours and the dynamic colour-changing effect of 3D-GRAM® CONTRUST are the essential ingredients for a security feature you can trust.

The patch can be applied both on paper and polymer-based banknotes.

The 100/50 Nobelists House Note Design

The house banknote commemorates two significant events for holographic science. 50 years ago, in 1971, the Hungarian physicist Dennis Gabor received the Nobel Prize “For his invention and development of the holographic method”. And 100 years ago, in 1921, the greatest scientist of our time, Albert Einstein, became the winner of the Nobel Prize in physics. The prize was awarded to Einstein for the discovery of the law of the photoelectric effect.

The 100/50 Nobelists note has a vertical orientation and mirrored portraits of Gabor and Einstein on the obverse. Such a design composition, featuring portraits of two great scientists, breaks the stereotypes of banknote graphics and singles out the 100/50 Nobelists design concept from conventional standards.

3D-GRAM® CONTRUST Patch Design

The patch design depicts contour portraits of scientists and the anniversary dates of the Nobel Prize. The concise design and mirror composition of the elements emphasize the colour-changing effect of the new security feature. When the banknote is rotated 180° a contrasting colour change of the images appears. The colours of the elements change places from red to green and vice versa.
