COMPOSITION FOR PEELABLE COATING |
摘要 |
A composition for peelable coating, which composition exhibits excellent properties such as film-formability and water resistance and can be dried at ambient temperature without any particular heating, to thereby provide excellent coating performance. The composition contains a core/shell copolymer including an acrylic copolymer portion A having a high glass transition temperature of 30.degree.C-70.degree.C and an acrylic copolymer portion B having a low glass transition temperature of 5.degree.C to -30.degree.C and being formed through multi-step polymerization. The core/shell copolymer is made up of 5-40 wt.% of the acrylic copolymer portion A and 60-95 wt.% of the acrylic copolymer portion B, on the basis of the total amount of the portion A and the portion B. The acrylic copolymer portion A and the acrylic copolymer portion B contain the same hard-polymer-providing monomer unit and soft-polymer-providing monomer unit. Each copolymer portion contains a hard-polymer-providing monomer unit and a soft-polymer-providing monomer unit in a total amount of 70 wt.% or more.
