Abstract
Abstract Resinous compositions comprising an acrylic resin containing, as polymer constituting units, 20 to 55% by weight of tri-organic tin alpha , beta -unsaturated carboxylate, 0.1 to 25% by weight of hydroxy bearing (meth)acrylate and the remainder of another polymerizable unsaturated monomer are provided. The compositions are useful as resinous vehicles for antifouling paints, capable of being gradually hydrolyzed in sea water, thereby resulting in a smooth coating surface and liberating an antifouling agent by themselves.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
80 words
A resinous composition for an antifouling paint comprising an acrylic resin containing, as polymer constituting units, 20 to 55% by weight of a tri-organic tin α,β-unsaturated carboxylate, and 0.1 to 25% by weight of a hydroxyl bearing (meth)acrylate wherein the hydroxyl bearing (meth)acrylate is 2-hydroxyethyl methacrylate, 2-hydroxyethyl acrylate, hydroxypropyl acrylate or hydroxypropyl methacrylate, the remainder of the polymer constituting units being another different polymerizable unsaturated monomer selected from the group consisting of alkylacrylates, alkylmethacrylates, acrylamides, styrene, vinyl toluene and acrylonitrile.
Claim 2
Dependent Claim
80 words
A resinous composition for an antifouling paint comprising an acrylic resin containing, as polymer constituting units, 20 to 55% by weight of a tri-organic tin α,β-unsaturated carboxylate, and 0.1 to 25% by weight of a hydroxyl bearing (meth)acrylate wherein the hydroxyl bearing (meth)acrylate is 2-hydroxyethyl methacrylate, 2-hydroxyethyl acrylate, hydroxypropyl acrylate or hydroxypropyl methacrylate, the remainder of the polymer constituting units being another different polymerizable unsaturated monomer selected from the group consisting of alkylacrylates, alkylmethacrylates, acrylamides, styrene, vinyl toluene and acrylonitrile.
