PEELABLE COATING COMPOSITION

摘要

PURPOSE: To provide a peelable coating composition having an excellent film- forming property, water resistance and the like as well as being capable of exhibiting performances of coating by drying at an ordinary temperature without needing a heating process. CONSTITUTION: This peelable coating composition of the present invention contains a core/shell copolymer formed by multi-step polymerization wherein the composition is constituted of: an acrylic copolymer portion A having a glass transition temperature in the range of 30 to 70 deg.C and an acrylic copolymer portion B having a glass transition temperature in the range of 5 to -30 deg.C ; A is present in an amount of 5 to 40 wt.% and 60 to 95 wt.% for B, based on the total weight of A and B; the acrylic copolymer parts A and B include units of the same hard and soft monomers; and the total amount of the units of the hard and soft polymers in each polymer is 70 wt.% or more.
