欧稳德防伪油墨红外线吸收剂家族新成员-----NIR-788

New member of OMNISTAB infrared absorber for anti-counterfeiting ink——NIR 788

近红外光（Near Infrared，NIR）是介于可见光（ⅥS）和中红外光（MIR）之间的电磁波，按ASTM（美国试验和材料检测协会）定义是指波长在780～2526nm范围内的电磁波，习惯上又将近红外区划分为近红外短波（780~1100nm）和近红外长波（1100~2526nm）两个区域。近红外区域是人们最早发现的非可见光区域。

Near Infrared (NIR) is an electromagnetic wave between visible and middle infrared light. According to ASTM, it refers to the electromagnetic wave with a wavelength of 780 ~ 2526nm.Conventionally,near infrared region is divided into two regions: near infrared short wave (780~1100nm) and near infrared long wave (1100~2526nm).The near infrared region was the first non-visible region to be discovered.

红外线吸收剂是近年来新兴的一种添加剂，其应用范围十分广泛，其中十分重要的一项就是应用在防伪油墨中。近红外吸收防伪油墨是通过把一种或几种近红外吸收材料加入到油墨中的方式制成。近红外吸收剂通常是一种有机功能染料，它在近红外区域有吸收，最大吸收波长700nm-1100nm，且震荡波长落在近红外区。添加了近红外吸收材料的油墨可以吸收红外线，如在印品的某一局部用这种油墨，在日光下无任何痕迹，但在检测仪器下，可观察到相应的信号或者暗纹。

Infrared absorber is a new additive in recent years, its application range is very wide, one of the most important application is used in anti-counterfeiting ink. we can get near-infrared absorption anti-counterfeiting ink by adding one or more nir absorbing materials into the ink. Nir absorber is an organic functional dye, which can absorb in the nir region. Its maximum absorption wavelength is 700nm-1100nm, and its oscillation wavelength falls in the near infrared region. The ink added infrared absorbing material can absorb infrared rays. If this ink is used on a part of the print, we can see nothing under daylight, but the corresponding signal or dark streak can be observed under the detector.

通常情况下，近红外吸收材料是有机高分子材料，其在高温下合成，生产加工工艺复杂，技术难度高，生产成本昂贵，因此近红外吸收防伪油墨耐高温、耐光照、性能稳定并且防伪效果好，仿造难度高。

In general, NIR is an organic functional dye. It is synthesized at high temperature, and its production and processing process is very complicated. It also has high technical difficulty level and production cost. Therefore, the infra-red fluorescent inks can withstand high temperature and long periods of light, it also has stable performance, good anti - counterfeiting effect, high imitation difficulty level.

红外防伪油墨的优点众多：防伪技术强，技术难度大，使用简单，几乎不受任何印刷条件的限制，可以印刷任何防伪图案，而且可用任何印刷方式，适用于票据、证券、钞票、商标等的防伪印刷。

The infra-red fluorescent inks has many advantages：it has strong anti-counterfeiting technology, high technical difficulty level and can be easy to use. It is almost free from any printing conditions. It can also be used for printing any security pattern. Besides, it can be printed in any way. And it is suitable for security printing , such as bills, securities, banknotes, trademarks, etc.

根据油墨对红外线有不同吸收能力的特点，还可以匹配制成无吸收红外防伪油墨和近红外防伪油墨。无吸收红外防伪油墨就是对近红外线不具有吸收作用的印刷油墨。使用时可以由近红外吸收油墨和无吸收红外防伪油墨组成一对。将近红外吸收防伪油墨印刷的防伪图案或信息隐藏在无吸收红外防伪油墨下，因此防伪功能更隐蔽，防复制功能更强，防伪效果也更好。

Because different inks have different absorption capacity of infrared, we can also make no absorption infrared anti-counterfeiting ink and near-infrared anti-counterfeiting ink. No absorption infrared anti-counterfeiting ink is a printing ink that does not absorb infrared rays. We can use the near infrared absorption ink and non - absorption infrared anti - counterfeiting ink into a pair. We can put near infrared absorption anti-counterfeiting ink printing anti-counterfeiting patterns or information hidden in the non-absorption infrared anti-counterfeiting ink, so anti-counterfeiting and anti-replication effect is better.

青岛德达志成化工有限公司在以色列设有研发中心，依托耶路撒冷大学先进的实验设备，经过多年的潜心研发，终于研制出了一款吸收峰狭窄且吸收率很高的新红外线吸收剂---OMNISTAB NIR-788。

Deltachem(Qingdao) Co.,ltd has a R&D center in Israel which rely on the advanced experimental equipment of the university of Jerusalem. After many years of research , we finally developed a new infrared absorber with narrow absorption peak and high absorption rate ——OMNISTAB NIR-788.

欧稳德NIR-788是一种特别适用于防伪油墨的红外线吸收剂，其自身的吸收范围窄，且吸收效率高，在防伪过程中表现出高度的灵敏性。

OMNISTAB NIR-788 is a special infrared absorber used for anti - counterfeiting ink , its own absorption range is narrow and it has high absorption efficiency , it also shows high sensitivity in the anti - counterfeiting process.
