What are fluorescent dyes and fluorescent pigments? *A comprehensive explanation of the differences and how to choose them by a specialized manufacturer.

A comprehensive explanation of fluorescent dyes and fluorescent pigments widely used in products that require visibility, such as safety signs, fluorescent markers, clothing, and printing inks!

Fluorescent dyes and fluorescent pigments are coloring materials that achieve brighter and more vivid colors than conventional colorants by absorbing ultraviolet (UV) light and emitting visible light. 【Selection Points】 When transparency is needed: Fluorescent dyes (high permeability to liquids and fibers) When weather resistance is required: Fluorescent pigments (excellent for outdoor use and long-term durability) For coloring solids such as plastic molding: Fluorescent pigments (suitable for high-temperature processing and good dispersibility) ■ Applications in textiles and clothing Fluorescent dyes are suitable. They have good permeability to fabrics, providing vivid colors and flexibility. However, care must be taken to avoid fading from washing and sunlight. ■ Applications in plastic molded products Fluorescent pigments are suitable. They can withstand high temperatures during injection molding and blow molding, allowing for uniform fluorescent color throughout the molded product. ■ Applications in printing inks Different types are used depending on the application. ■ Offset printing: Fluorescent pigment-based Screen printing: Both fluorescent pigments and dyes, solvent-based inks: Fluorescent dyes, safety signs and warning displays → Fluorescent pigments are mainstream. Due to the demand for durability and high visibility in outdoor use, fluorescent pigments with excellent light resistance are chosen. *For more details, please download the PDF or contact us directly.
