A magnetic body, a curable composition comprising the same, and a method for manufacturing the same are disclosed herein. In some embodiments, a magnetic body includes magnetic particles, and a surface treatment agent bonded to the surface of the magnetic particles, wherein the magnetic particles comprise crystals having a size in a range of 10 nm to 40 nm, wherein the magnetic particles have an average particle diameter in a range of 20 nm to 300 nm, and wherein the magnetic particles have a particle diameter variation coefficient in a range of 5% to 30%. The magnetic body may have an excellent calorific value, and at the same time, may maintain the calorific value uniformly. In the magnetic body, the calorific value characteristics may be freely adjusted. The curable composition of the present application can be easily cured by using a magnetic body that satisfies all the characteristics.

A composition for use as a drier in auto-oxidizable coatings or as an accelerator in unsaturated polyester resins comprises a manganese-bearing polymer having a manganese dicarboxylate repeating unit and at least one nitrogen-containing donor ligand. Such compositions offer excellent drying performances. They ensure a strongly reduced leachability of manganese compared to that of known manganese-bearing driers.

A golf ball of one aspect of the present invention includes a spherical core, one or more cover members to cover the core, and a coating layer to coat a cover member configuring an outermost layer of the one or more cover members. A plurality of dimples is formed in the cover member. Shore-D hardness of the cover member is equal to or larger than 50. A 10% modulus of the coating layer is equal to or smaller than 160 kgf/cm.sup.2. Roughness is produced on a surface of the coating layer after applying a coating material over the cover member of the outermost layer A maximum height Rz of the coating layer is equal to or larger than 3 μm.

An object of the present invention is to provide a golf ball having excellent color development stability. The present invention provides a golf ball comprising a core and a cover covering the core, wherein the cover is formed from a resin composition containing a first base resin and a fluorescent pigment, and the fluorescent pigment has a number-based cumulative median size of 2.5 μm or more.

A multilevel antimicrobial polymeric colloidal particle includes a polymer scaffold and at least one antimicrobial polymer carried on the polymer scaffold, where the polymer scaffold and the at least one antimicrobial polymer form a hollow colloidal particle. An antimicrobial core may be received within the hollow colloidal particle. The multilevel antimicrobial polymeric colloidal particles may be incorporated into an optically clear acrylic material to form an antimicrobial coating. The antimicrobial coating may be coated and ultraviolet cured onto a glass, metal or plastic substrate or the like to form a screen for electronic devices or the like which has antimicrobial properties.
