FLUORINATED POLYURETHANE ACRYLATE COPOLYMER AND HARD COATING COMPOSITION COMPRISING THE SAME

摘要

A fluorinated polyurethane acrylate copolymer is provided to ensure excellent antifouling property and scratch resistance by using an polyurethaneacrylate oligomer with good hardness and a fluorinated acrylate monomer with low surface energy. A fluorinated polyurethane acrylate functional copolymer is a (meth)acrylate oligomer and a fluorinated (meth)acrylic monomer. The (meth)acrylate oligomer and a fluorinated (meth)acrylic monomer are included in a ratio of 60:40 ~ 50:50. The average molecular weight of polyurethane (meth)acrylate oligomer is 1000~3000. The hard coating liquid comprises the fluorinated polyurethane acrylate functional copolymer, binder and photoinitiator.
