Coated resin particles and method for producing coated resin particles

A coated resin particle comprising:

• a water-absorbent resin particle;
• and
• a coating layer that coats at least a part of a surface of the water-absorbent resin particle,
• wherein the coating layer is chemically and/or physically bonded to the surface of the water-absorbent resin particle,
• the coating layer contains a water-soluble component in which a solubility in 100 g of water is in a range of 1.0 g or more and 5 g or less at 25° C., and an organic water-insoluble component with a solubility in 100 g of water of less than 1.0 g at 25° C.,
• the water-absorbent resin particle contains a crosslinking polymer having a monomer unit derived from an ethylenically unsaturated monomer, and
• the ethylenically unsaturated monomer contains at least one selected from the group consisting of (meth) acrylic acid and a salt thereof, and the degree of neutralization of the acid group in the ethylenically unsaturated monomer is 50 to 90 mol %,
• the organic water-insoluble component comprises a copolymer of an alkene and a water-soluble ethylenically unsaturated monomer, wherein the alkene is at least one selected from ethylene, propylene, and butene, and
• the water-soluble component comprises a compound that is at least one selected from the group consisting of polyalkylene oxide, polyalkylene glycol, polyoxyalkylene alkyl ether, and a copolymer of monomers constituting these polymers.
