Due to its bright pink color and fluorescent properties, it is widely used in fields such as ink, textiles, and biological dyeing.

The application of ink is mainly reflected in the following aspects:

Characteristics of basic rhodamine b

-Bright color: presenting a bright pink or purple red color with high coloring power.

-Fluorescence effect: emits strong fluorescence under ultraviolet light, suitable for special visual effects.

-Solubility: Easy to dissolve in water and ethanol, and requires modification or emulsification treatment in oily media.

-Chemical stability: Moderate light resistance, relatively stable under acidic or neutral conditions, but may fade in strongly alkaline environments.

Application in water-based ink:

-Applicable fields: label printing, packaging paper, artistic creation, etc.

-Advantages: Directly utilizing its water solubility, environmentally friendly and low toxicity, suitable for light printing on food packaging.
