Abstract: 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 period and be not ready to develop cracks and other defects, thus exhibiting a excellent long-term antifouling performance. The composition contains an acrylic resin having at least one group represented by the following general formula (1): (wherein R1, R2 and R3 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.

Abstract: A substrate resin having pendant acid groups is produced by copolymerizing an acrylic or methacrylic ester of which alcoholic residue includes a bulky hydrocarbon radical or a soft segment. The substrate resin is then metallized together with an organic mobobasic acid so that both of the pendant acid group and the organic monobasic acid group are bount to the same metal atom. The resulting hydrolyzable metal-containing resin is incorporated into self-polishing antifouling paint formulations together with an antifouling pigment such as cuprous oxide.

Abstract: An antifouling paint containing a copolymer including a recurring unit of the formula: ##STR1## wherein R.sup.1 is hydrogen atom, methyl or an alkoxycarbonyl, R.sup.2 is hydrogen atom or an alkoxycarbonyl, A is an acid ion-terminated pendant group, M is a transitional metal ion, L is a monobasic organic acid ion, and m is the valency of the transitional metal M; and an amount of an organic ligand capable of coordinating to the transitional metal. The ion-association and reactivity of the metal in the copolymer may be retarded by complexing with the organic ligand in situ.

Abstract: A resin composition to be used as a resinous vehicle for an antifouling paint and a process for preparing the same, comprising reacting a mixture of(A) an acid group containing base resin having an acid value in the range of 25-350 mg KOH/g, selected from the group consisting of vinyl resin, polyester resin, alkyd resin and epoxy resin,(B) a metallic salt of low boiling organic basic acid having a boiling point in the range of 100.degree.-240.degree. C., the metal is selected from metals having a valence of 2 or more and a lesser ionization tendency than alkali metals, and(C) an organic monobasic acid having a boiling point of 20.degree. C. or more higher than said low boiling organic basic acid at an elevated temperature which is lower than the decomposition temperature of said metallic salt of said low boiling organic basic acid, while removing the formed low boiling organic basic acid out of the system. The subject composition provides superior antifouling coating compositions.
