At present, with the rapid development of ink industry, the quality and grade of ink products are getting higher and higher, and people's requirements on the appearance of products are becoming more and more demanding. Fluorescent whitening agent is also essential for ink manufacturers, but which whitening agent is suitable for ink use? Let's take you to know about it.

Ink mainly expresses characters or patterns on the substrate by printing or inkjet printing. Now, most of the inks are made of environmentally friendly materials, which are generally divided into water-based ink and oily ink in solvents. Different solvent-based inks use different whitening agents. Today, we mainly talk about oil-soluble ink whitening agents.

Oil-soluble ink is used in our common food, beverage, tobacco and alcohol, packaging and printing of daily necessities that come into contact with human body, etc. The packaging of these products will have higher requirements for ink, so there will be certain requirements for choosing fluorescent whitening agents. As the fluorescent whitening agent that can meet the printing requirements, we suggest to choose the oil-soluble ink fluorescent whitening agent OB.

How does fluorescent whitening agent OB brighten ink? We should know the principle of fluorescent whitening agent. It is an optical effect. Its fluorescence mainly comes from ultraviolet light. It absorbs the invisible ultraviolet light in sunlight, and then emits it in a bright and gorgeous fluorescent form in the blue-purple visible light region. This kind of blue-violet light can be mixed with yellow light in white ink to get white light, so that the ink we see will be white and bright.

The fluorescent whitening agent OB is mainly used for oil-soluble inks, such as paints, hot melt adhesives and inks, whitening and brightening. Its appearance is white powder, and its dosage is small. Only 200g is added to a ton of ink products, and the whitening and brightening effect of the products will be very obvious, which does not increase any cost.
