Abstract
Abstract Flock-coated metal sheet with excellent corrosion resistance and fabricability produced by applying an anticorrosive synthetic resin containing an anticorrosive pigment on the surface of a metal sheet such as a steel sheet to obtain an anticorrosive synthetic resin layer with a dried film thickness of 2 to 20 microns, coating said synthetic resin layer partially or completely with an elastic adhesive with a dried film thickness of 50 to 500 microns, and electrostatically flock-coating synthetic resin pile on said adhesive layer.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
103 words
A flock-coated metal sheet with excellent corrosion resistance and fabricability, comprising (a) an anticorrosive synthetic resin layer containing 2 to 30 parts by weight of an anticorrosive pigmemt per 100 parts by weight of the resin with a thickness of 2 to 20 microns as a dried film on the surface of a metal sheet, (b) an elastic adhesive layer with a thickness of 50 to 500 microns as a dried film on a partial or the entire surface of said anticorrosive synthetic resin layer, and (c) flock-coated synthetic resin pile on said adhesive layer, applied by means of an electrostatic flock-coating machine.
Claim 2
Dependent Claim
103 words
A flock-coated metal sheet with excellent corrosion resistance and fabricability, comprising (a) an anticorrosive synthetic resin layer containing 2 to 30 parts by weight of an anticorrosive pigmemt per 100 parts by weight of the resin with a thickness of 2 to 20 microns as a dried film on the surface of a metal sheet, (b) an elastic adhesive layer with a thickness of 50 to 500 microns as a dried film on a partial or the entire surface of said anticorrosive synthetic resin layer, and (c) flock-coated synthetic resin pile on said adhesive layer, applied by means of an electrostatic flock-coating machine.
Claim 3
Dependent Claim
51 words
A flock-coated metal sheet according to claim 1, in which the anticorrosive synthetic resin layer comprises at least one resin selected from the group consisting of epoxy resin, phenol resin, polyester resin, urethane resin, and at least one anticorrosive pigment selected from the group consisting of zinc chromate and strontium chromate.
Claim 4
Dependent Claim
47 words
