Abstract: A sport ball is provided with an outer ball surface which has portions having a roughness higher than the portions of the surface. These rougher portions are obtained by applying, using a serigraphic process, a coating composition comprising a binder and an inorganic builder, the latter advantageously including a combination of substances having hydrophilic and hydrophobic properties.
