WASHABLE WATERBORNE INK

摘要

The invention relates to a washable waterborne ink comprising a copolymer or a salt thereof of an aliphatic carboxylic acid-functional aliphatic monomer and an non-functional aliphatic monomer in a weight ratio between the carboxylic acid-functional aliphatic monomer and the non-functional aliphatic monomer, such that it allows water solubility and simultaneously imparts a good dye blocking effect.
