Acid Yellow 110 is a stilbene-class acid dye specifically valued for its very good lightfastness on polyamide fibres. It gives a neutral to slightly reddish-yellow shade and is particularly effective for dyeing nylon where colour durability against light exposure is a key requirement. This dye demonstrates good build-up and exhaustion properties in an acidic dyeing medium. Its applications are focused on high-quality nylon textiles and certain specialty paper grades where lightfastness is a primary concern.
