- 摘要：
PURPOSE: To form a clear coated film having resistance to printing by treating a substrate with an aqueous composition containing an aqueous dispersion of copolymer particles which have at least two mutually incompatible phases and an average particle size of 20-70 nm. CONSTITUTION: An aqueous dispersion of copolymer particles which have at least two mutually incompatible phases and an average particle size of 20-70 nm is prepared. A clear coated film having resistance to printing and excellent in appearance is formed by coating a substrate with the aqueous dispersion of the copolymer particles and drying the resultant substrate. The copolymer having a Tg lower than 35 deg.C is suitable as the copolymer used in the outer phase of the copolymer particle and the copolymer having a Tg higher than 45 deg.C is suitable as the copolymer used in the inner phase of the copolymer particle. The suitable weight of the copolymer used in the outer phase is in the range of 20-95 wt.% based on the total particle weight.
