Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
84 words
In a precoated metal sheet comprising a metal sheet and an acrylic resin coating, the improvement which comprises an acrylic resin coating comprising a dispersion of a granular rubbery material in an acrylic-based resin matrix which resin matrix contains monomer units having functional groups which cross-link upon heating and which resin matrix is glassy at room temperature, said resin coating comprising from 70 to 99 wt. percent of said acrylic-based resin matrix and from 1 to 30 wt. percent of said granular rubbery material.
Claim 2
Dependent Claim
84 words
In a precoated metal sheet comprising a metal sheet and an acrylic resin coating, the improvement which comprises an acrylic resin coating comprising a dispersion of a granular rubbery material in an acrylic-based resin matrix which resin matrix contains monomer units having functional groups which cross-link upon heating and which resin matrix is glassy at room temperature, said resin coating comprising from 70 to 99 wt. percent of said acrylic-based resin matrix and from 1 to 30 wt. percent of said granular rubbery material.
Claim 3
Dependent Claim
20 words
The pre-coated metal sheet of claim 1, wherein the thickness of said acrylic resin coating is 20 to 200 μ.
Claim 4
Dependent Claim
22 words
The pre-coated metal sheet of claim 1, wherein said monomer units range from 1 to 30 wt % of said resin matrix.
Claim 5
Dependent Claim
45 words

Claim 7
Dependent Claim
23 words
The pre-coated metal sheet of claim 1, wherein the rubbery material is selected from the group consisting of acrylic rubbers and diene rubbers.
Claim 8
Dependent Claim
21 words
The pre-coated metal sheet of claim 1, wherein the size of said granular rubbery material is 0.05μ to 15μ in diameter.
