YTBELAGD PAPPERSPRODUKT

摘要

In a copolymer latex for use as a binder in paper coatings the copolymer prepared from ethylenically unsaturated monomers consisting of a monovinyl aromatic hydrocarbon monomer, an aliphatic conjugated diene hydrocarbon and an unsaturated mono- or di-carboxylic acid is modified by reaction with an epoxide prior to addition of any other colloidal water-dispersible polymer or fillers and/or pigments to produce a coating composition which has controlled viscosity and reactive groups as sites for additional crosslinking if necessary.
