Structural Color Inkjet Technology Adopted in the Exterior of the “DYNAMIC EQUILIBRIUM OF LIFE”, One of the Signature Pavilions of Expo 2025 Osaka Japan
With a sophisticated aesthetic appeal which is reminiscent of living organism, the pavilion embodies the theme Quest of Life
April 10, 2025
Tokyo, April 10, 2025 – FUJIFILM Business Innovation announces that its Structural Color Inkjet Technology has been implemented to paint on the exterior of one of the signature pavilions called "DYNAMIC EQUILIBRIUM OF LIFE" at the Expo 2025 Osaka, Japan (hereinafter: Expo 2025), which will be held from April 13 to October 13, 2025.
Structural Color Inkjet Technology is Fujifilm's proprietary decorative technology that uses inkjet printing to create a structural color, a coloration phenomenon that occurs through the reflection of light, without using pigments or dyes, making it possible to achieve an unprecedented level of aesthetic appeal. The sophisticated aesthetic appeal of Structural Color Inkjet Technology that reminisces living things was highly evaluated and selected to paint the pavilion which themed as “Quest of Life”.

The Signature Pavilions are located at the center of the Expo 2025 site, and serve as the starting point for the Signature Project (Brilliance of Life Project) pavillion developed by eight leading professionals in various fields, each of them has a different theme. One of these pavilions is called DYNAMIC EQUILIBRIUM OF LIFE, which is being developed by Shin-Ichi Fukuoka, a biologist, under the theme of Quest of Life.

About Structural Color Inkjet Technology
The structural colors inspired by nature have been used in decorative items since ancient times. Fujifilm Group's molecular control technology is applied to Structural Color Inkjet Technology to create fine structures in the ink that is ejected onto a film base material, causing it to produce the color. By preparing multiple types of ink that produce structural colors with different hues, and by adjusting the combination and density of the inks, it is possible to dye in many structural colors and gradients to achieve a high level of aesthetic appeal.
Furthermore, Structural Color Inkjet Technology can be combined with a variety of light sources to create a wide range of color expressions so that it is suitable for decorating transparent resins and glass. These characteristics are apparent in the exterior of the pavilion.
In addition to the watch faces, art pieces, and ornaments that have been decorated with this technology so far, it can also be used for interior and exterior design. Also, because it can be controlled the reflection and transmission of light, it can be applied to spatial design, such as decorating solar panels and displays.
In the future, we plan to leverage the aesthetic appeal of this technology and expand its applications across a wide range of purposes by combining it with new processing technologies.
Features of Structural Color Inkjet Technology
Full-color structural color
①Expression of full-color structural color
By combining multiple inks that produce structural colors of different hues, it is possible to express full-color structural colors ranging from red to blue, depending on the wavelength of light.
Examples of structural color patterns
②Expression of structural color patterns and gradients
Since structural colors using inkjet printing can be freely depicted, it is possible to express patterns in a variety of hues and gradients with varying color densities.
In addition to being able to reproduce the colors of morpho butterflies, jewel beetles, and other colorful lifeforms that exist in nature using printing, it is also possible to create structural colors from the design data of choice. An unprecedented level of aesthetic appeal are possible, including structural colored wood grain patterns that do not exist in the natural world.
The color of the same printed materialchanges depending on the angle of view
③The color changes depending on the angle of view
The hue of the same printed material changes depending on the angle of view.
④Controlling light reflection and transmission
The hue also changes depending on the background color. When structural color is added to a black background, the transmitted light is absorbed and the reflected color of the structural color is visible. But on a white background, the transmitted light is not absorbed and the complementary color becomes visible.
Comparison between dyes/pigments colors and structural colors
By combining such features, Structural Color Inkjet Technology has the potential to create decorative expressions that make use of light. It also enables combining of functions and designs that make use of light in novel and original ways. Furthermore, this technology enables on-demand printing of structural colors that do not exist in nature, expressed through various file formats. This feature creates a completely new level of aesthetic appeal.
