Abstract
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.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
124 words
A sport ball having an external surface which is locally covered at a plurality of sites which are widely distributed over said surface, by an adhering coating composition, and which remains uncoated by said coating composition throughout a remainder which is interspersed between and among said sites; said coating composition comprising a binder having mixed therein at least one inorganic particulate builder which is a hydrophilic material, said hydrophilic material having a surface area of more than 40 m 2 /g and a specific gravity of less than 100 g/l; said coating composition protruding from said surface as bumps and providing said sport ball with a greater surface roughness at said sites than does said external surface on said remainder of said external surface.
Claim 2
Dependent Claim
124 words
A sport ball having an external surface which is locally covered at a plurality of sites which are widely distributed over said surface, by an adhering coating composition, and which remains uncoated by said coating composition throughout a remainder which is interspersed between and among said sites; said coating composition comprising a binder having mixed therein at least one inorganic particulate builder which is a hydrophilic material, said hydrophilic material having a surface area of more than 40 m 2 /g and a specific gravity of less than 100 g/l; said coating composition protruding from said surface as bumps and providing said sport ball with a greater surface roughness at said sites than does said external surface on said remainder of said external surface.
Claim 3
Dependent Claim
42 words
The sport ball of claim 1, wherein: said coating composition further comprises at least one builder which is a hydrophobic material mixed into said binder, said hydrophobic material having a specific gravity of about 0.1 to less than 0.4 kg/dm 3 .
Claim 4
Dependent Claim
26 words
The sport ball of claim 1, wherein: said binder is at least one compound selected from the group consisting of polyurethane, styrene-butadiene, butadiene-acrylonitrile, polyacrylate and polymethacrylate.
Claim 5
Dependent Claim
19 words
The sport ball of claim 1, wherein: said hydrophilic material has a particle size of about 4-50 nm diameter.
Claim 6
Dependent Claim
26 words
The sport ball of claim 4, wherein: said hydrophilic material is at least one inorganic compound selected from the group consisting of glass and pyrogenated silica.
Claim 7
Dependent Claim
30 words
The sport ball of claim 5, wherein: said hydrophilic material is present in a said binder at a ratio of hydrophilic material to binder of about 30 to 70 g/kg.
Claim 8
Dependent Claim
20 words
The sport ball of claim 2, wherein: said hydrophobic material has a particle size of about 10-200 microns in diameter.
Claim 9
Dependent Claim
35 words
The sport ball of claim 7, wherein: said hydrophobic material is air filled and is at least one inorganic material selected from the group consisting of air-filled microspherules of glass and air-filled microspherules of silica.
Claim 10
Dependent Claim
19 words
The sport ball of claim 8, wherein: said glass in an alkaline or alkaline earth silicate or borosilicate glass.
Claim 11
Dependent Claim
29 words
The sport ball of claim 8, wherein: said hydrophobic material is present in said binder at a ratio of hydrophobic material to binder of about 10 to 50 g/kg.
Claim 12
Dependent Claim
41 words
The sport ball of claim 1, wherein: each said site has a width of about 20-200 microns, each said bump projects outwards about 15-100 microns from said external surface, and said bumps are spaced from one another by about 2-5 mm.
Claim 13
Dependent Claim
12 words
The sport ball of claim 1, wherein: said binder is substantially transparent.
Claim 14
Dependent Claim
38 words
The sport ball of claim 1, wherein: said coating composition further comprises a die mixed into said binder, whereby said coating composition is provided with a color which is visually distinctively different from that of said external surface.
Claim 15
Dependent Claim
20 words
The sport ball of claim 1, wherein: said coating composition further comprises a stabilizer against photochemical decay of said binder.
Claim 16
Dependent Claim
11 words
The sport ball of claim 1, configured as a soccer ball.
