Acrylharpiks og antifouling-belægning

摘要

The present invention has for its object to provide an antifouling coating improved in such a manner that the coating film formed therefrom may retain a steady polishing rate over a long time period and be not ready to develop cracks and other defects, thus exhibiting a excellent long-term antifouling performance. An acrylic resin having at least one group represented by the following general formula (1): (wherein R<1>, R<2> and R<3> may be the same or different and each represents a hydrocarbon residue of 1 to 20 carbon atoms) in its side chain and additionally at least one group represented by the following general formula (2): (wherein X is a group represented by the formula: n is equal to 0 or 1; Y represents a hydrocarbon; M represents a divalent metal; and A represents a monobasic organic acid residue)in its side chain.
