An antifouling paint composition comprising a binder resin composition containing a biodegradable resin being obtained by polymerizing a cyclic lactone compound with at least two active hydrogen groups of a compound containing at least two active hydrogen groups in one molecule, and an antifouling additive being mixed with the binder resin composition in a weight ratio of the binder resin composition to the antifouling additive from 1:2 to 7:1, the binder resin composition having a gel fraction of not more than 5% by weight.

Biodegradable resin composition ADN antifouling paint composition

Disclosed is an organic polymer microparticle which is obtainable from copolymerization of (a) an ethylenically unsaturated amine polymer obtained by reacting an amine polymer having at least two primary amino groups with 0.01 to 0.99 molar equivalents based on the amount of the primary amino group, of an unsaturation introducing monomer having at least one functional group which is reactive with the primary amino group and an ethylenic double bond with (b) 10 to 99000 parts by weight based on the total amount (100 parts by weight) of the amine polymer and the unsaturation introducing monomer, of a matrix forming ethylenically unsaturated monomer, in an aqueous medium. A process for producing the organic polymer microparticle is also disclosed.

Organic polymer microparticle and process for producing the same

The present invention provides a toner which substantially excludes off set and blocking of the toner particles, and a process for preparing the toner. The toner is prepared by dispersion-polymerizing a vinyl monomer in the presence of a dispersion polymerization stabilizer, a polymerization initiator and silicone-containing organic resin microparticles in a dispersion medium which dissolves said vinyl monomer, dispersion polymerization stabilizer and polymerization initiator and which does not dissolve said silicone-containing organic resin microparticles and resulting toner particles.

Method of producing a toner comprising silicone containing organic resin

The invention relates to a novel hydrolyzable silicone resin composition comprising a polysiloxane having at least one polyvalent metal ester group represented by either one of the following formulae:
