Abstract
Coated particulate materials comprise water-soluble particulate materials as cores and a coating deposited on the surface of the particulate materials and formed preponderantly of a copolymer of cyclopentadiene type oligomer and an unsaturated fatty acid oil. Said coated particulate materials are manufactured by coating the surface of water-soluble particulate materials with a copolymer composition of a cyclopentadiene type oligomer and an unsaturated fatty acid oil and subsequently curing the resultant coating.
