Fluorescent pigments and dyes play a crucial role in today's security measures, serving diverse industries and sectors such as government, retail, manufacturing, banking, aircraft, and ID verification. With over two decades of experience, iSuoChem has established itself as a reputable manufacturer of fluorescent pigments and dyes. In an effort to enhance understanding of these chemical substances, we have created a comprehensive guide covering the following topics:

What Are Fluorescent Pigments and Dyes?

Pigments and dyes are chemical substances used for coloring materials, often referred to as colorants. Fluorescent pigments and dyes are a special category of colorants that absorb light energy at a specific wavelength, such as invisible ultraviolet light (UV), and then emit light at a longer wavelength, resulting in a distinct color.

Another way to describe the process of fluorescence is that higher energy light, with shorter wavelengths, excites the fluorescent material to emit lower energy visible light, characterized by longer wavelengths. Depending on their physical and chemical properties, fluorescent materials can emit various colors across the visible color spectrum.

For more in-depth information on fluorescence, as well as its relation to Phosphorescent pigments, we invite you to explore our blog post titled "What are Fluorescent Pigments? " At the end of the blog, you will get some explanations.

Two Main Types of Fluorescent Pigments &Dyes

1. Visible Fluorescent Pigments and Dyes (Daylight type)

Visible fluorescent pigments and dyes are colorants that exhibit enhanced brightness when stimulated by light. These colors, often referred to as daylight-fluorescent colors, amplify the visible color reflected by the material, creating an intense glow.

The standout feature of daylight-fluorescent materials is their remarkable visibility, making them ideal for applications such as:

Advertising board

Safety products (Road safety and Protective clothing)

In addition, daylight fluorescent pigments and dyes are also widely used in textile printing, garment dyeing, pad dyeing, paper coatings, leather, plastic (PE/PP/PVC/EVA), rubber and plastic(TPR/TPE/TPU/TPV) , paint ink, Consumer products (toys, paints, highlighter pens, tags, and labels) and other fields.

2. Invisible Fluorescent Pigments and Dyes (UV Anti-fake type)

Invisible fluorescent pigments and dyes are colorants that appear nearly colorless under standard white light. They only emit a visible color when exposed to light of a shorter wavelength, such as invisible ultraviolet light (UV). The emitted color is visible only as long as the material remains under excitation. Once removed from the excitation light, the production of visible color ceases.

Furthermore, certain materials exhibit different colors depending on the specific wavelength of the UV light. This characteristic makes invisible fluorescent pigments and dyes exceptionally suitable for applications that require hidden or covert features, including:

Anti-fake

Document security

Brand protection

Identification verification

Process control

Defect detection

Additionally, invisible fluorescent materials find extensive use in medical and scientific research applications.

Tips: In addition to UV fluorescent anti-counterfeiting pigments, iSuoChem is also making infrared fluorescent anti-counterfeiting pigments.

Fluorescent pigments and dyes offer a wide range of benefits across various industries, from enhancing visibility and attracting attention to enabling covert features for enhanced security and control.
