POLYUREA FILM AND METHOD OF FORMING THE SAME

摘要

It is an object of the invention to prepare a polyurea film with excellent transparency, light resistance and mass-scale productivity on a substrate of a resin-molded article by a method of vacuum deposition polymerization. A polyurea film obtained by vacuum deposition polymerization of an aromatic alkyl-, alicyclic- or aliphatic diisocyanate monomer and an aromatic alkyl-, alicyclic- or aliphatic diamine monomer, where the diisocyanate monomer and the diamine monomer are selected from diisocyanate monomers and diamine monomers in a relation such that the difference in the activation energy required for the elimination from a substrate between these monomers is 10 kJ or less.
