Toray’s film works due to the use of a wrinkled nanometer surface, known as a wet coating, that makes it difficult for fingerprints to stick to. That is further enhanced by coating the surface with an oil-repelling material. The end result is a film that picks up far fewer fingerprint marks, or at the very least presents them as less visible as the image below demonstrates:
"Previously, there were mainly two types of fingerprint-resistant technology - oil-attracting and oil-repelling types. But there's a trade-off with those, either a lot of finger grease sticks to the film, or the marks are highly visible. By contrast, the aim of Toray's technology is to provide the ultimate option, which is that not only do fewer fingerprints stick to the film, but they're also less noticeable."
"Let me explain using this acrylic panel with film on it. If you leave an oily fingerprint, it's like applying a stamp with oil. With previous films, the oil sticks fast. With this film, the fingerprint still leaves a trace, but it's very hard to see. That's a feature of the new film."
"We'd like this film to be used where it's important to prevent fingerprints, so for example, as a protective sheet for touchscreens, or a glossy decorative material. We're still at the R&D stage, so we'd like to get feedback from all kinds of users, to make this film even more effective."
