VATTENDISPERSIONER AV FLUORESCERANDE PIGMENT

摘要

An aqueous dispersion of a fluorescent pigment comprising: a water insoluble polymer; fluorescent dye; emulsifiers; and water. The polymer comprises: a water insoluble vinyl monomer free of polar groups; vinyl nitrile; a vinyl monomer containing sulfonate groups; and a polar vinyl monomer from the group consisting of: polar acrylate esters; vinyl acetate; polar methacrylate esters and a substituted acrylamide containing hydroxyl or carboxylic ester groups. The invention also relates to a fluorescent pigment and method for preparing the dispersion and pigment.
