An object of the present invention is to provide an antifouling paint composition which shows an excellent antifouling effect in seawater for a long period of time, and has excellent adhesion and recoating properties to a substrate. The present invention relates to an antifouling pain composition comprising a copolymer which is obtained by polymerizing a monomer mixture comprising silicon-containing polymerizable monomer (a) having two (meth)acryl end groups, and which contains bivalent metal atom. The copolymer is also obtained by polymerizing a monomer mixture comprising silicon-containing polymerizable monomer (b) having one (meth)acryl end group, and metal atom containing polymerizable monomer (c,) having two unsaturated groups and metal atom selected from Mg, Zn, and Cu.

Antifouling paint composition

A metal-containing monomer dissolved mixture comprising a reaction product of an inorganic metal compound with a carboxyl group-containing radical polymerizable monomer, an organic solvent including at least an alcohol-based solvent, and water, wherein the water content is from 0.01 to 30% by weight; a metal-containing resin obtained by copolymerizing the metal-containing monomer (A) in this dissolved mixture with the other radical-polymerizable unsaturated monomer (B); an antifouling paint composition obtained by using this metal-containing resin; and an antifouling paint composition comprising a divalent metal-containing resin (C), a compound (D) of R &mdash;SH (wherein, R represents an organic group having 1 to 30 carbon atoms.), and copper oxide (E), are disclosed.

Thermosetting coating composition

A floppy disk in which the binder for fixing a magnetic substance in the recording layer of the magnetic disk is a polyester polyurethane and the liner of the jacket contains an acrylic fiber and in addition a fiber treating agent having a surface tension in a specific range. The floppy disk is excellent in workability, can be prepared in high yields because the number of dusts generated upon its preparation is small, and also is excellent in the permanence of recording performance.

Floppy disk

Insectproofing fibers are disclosed in which the surface of the fibers is coated with a mixture of an organic insectproofing agent, an organic insectproofing agent included in a monomer-trimer type cyclodextrin having an average molecular weight of 3000 or less and an organopolysiloxane, and the interior of the fibers is also impregnated with the mixture. The insectproofing fibers have an insectproofing effect against bugs for a long period of time and the effect is durable.
