Are you familiar with VantaBlack?
Hi, I'm Teppei, the person-in-charge of KoPro.
Are you familiar with VantaBlack?
Known as "The darkest artifact in the world," it was developed by a British company, Surrey Nanosystems. It is a coating of carbon nanotubes, and is expected to be used in various industrial applications.
"Ultimate black" seems to attract people in terms of visual aspect. An artist named Anish Kapoor of Great Britain has acquired exclusive rights over artistic use of VantaBlack.
Another artist developed another black paint "Black 2.0" to compete against VantaBlack. It is blacker than any other art item, except VantaBlack, and can be used by any artist except Anish Kapoor.
Introduction of Anti-reflective paint
Our company deals with anti-reflective materials, so we definitely want to verify their performance. For this test, I would like to verify anti-reflective materials with interesting background stories, "VantaBlack" and "Black 2.0".
Unfortunately, I cannot obtain "VantaBlack" casually. The first thing I would need to do is to contact the development source, Surrey NanoSystems. Just asking for a sample (an aluminum sheet painted with VantaBlack) requires an explanation of purpose and a description of it in a licensed document based on the UK export control law. I am sorry but it will be very difficult to proceed with this test using VantaBlack.
Next, I tried obtaining "Black 2.0". Black 2.0 is also made in UK, but it can be purchased with a single click from a Japanese distributor at Amazon Japan.
The price was a little less than 4000 yen for 150 ml. It is quite a price, but I bought it.
If you look at the product's photos of Black 2.0 (from Amazon), you may sense a strong rivalry with VantaBlack. The paint was coated on a crumpled aluminum foil similar to VantaBlack. However, every photo is black and it is a little difficult to tell how dark it is.
Next is a Japanese representative! Turner's Acrylic Gouache Jet Black. This is an acrylic paint, but it is a famous paint that is well known to people in the camera industry as a DIY antireflective paint. For example, the inner surface of an inexpensive mount adapter is sweetened with anti-reflection treatment, so there are many who paint it there. It is only 540 yen for 40 ml. Incredible!
The last is a black acrylic paint purchased at a 100yen shop. It is solely for the comparison.
Let's begin the test
Since it absorbs water when it is applied to drawing paper, I decided to apply it on a poly plate which is as a flat resin plate.
First, apply masking tape to set boundary and apply paint (we are using the acrylic paint bought from the 100yen shop in this photo).
Next, apply Black 2.0 on the side.
Just drip a certain amount of the product and spread it over the desired area. The viscosity has almost the same feeling as an ordinary acrylic paint.
As you can see, the result here is that Turner's Jet Black is blacker than Black 2.0. This is to be as expected as Turner products are well-known in the camera crazed world. I think the blackness and “matte”ness of Turner's Jet Black is better than Black 2.0. Up until now, it's been a mystery to how Black 2.0 has been advertised as the world's most matted black ink.
However, Turner's Jet Black also has its drawbacks. Especially its lack of abrasion resistance.
Even by touching it lightly, marks will become evident. If touched even by a single finger, it will absorb the skin oil, or a clear white mark will retain on the surface. The matte surface after painting is very delicate and is difficult to operate unless it is not touched at all. Please be careful.
The powder fall problem (with the camera) is not so serious in this case. I didn't get any powder on my hands when I touched it.
The matte surface of Black 2.0 has a slightly rough touch, and the trace is less noticeable even if touched. Perhaps the matte layer is made of microbeads. In addition, I can feel that the concealability is very good because I can not see the ground even in the thin film part.
(By the way, when I compared the reflection prevention processing of the lens hood inside of Nikon, it was the same level as Black 2.0.)
Conclusion : Turner's Jet Black is blacker than Black2.0!! (But never touch it!)
In that case, how does KOYO's antireflective material compare against Turner's Jet Black?
Further conclusion! If you want even more black, USE FineShut! (You can even touch it without any worry!)
Our product is of great success. And we hope that our FineShut will help you for various purposes. Thank you very much for reading to the end!
We will begin sales of our black paint "Musou Black" soon! This is the blackest water-based acrylic paint in the world! It has a light absorption rate of 99.2% in the visible light range, which is equivalent to that of our black material, FineShut KIWAMI.
