Abstract
Abstract An improved sheet material for corrosion inhibition of the surfaces of packaged ferrous metal products which comprises a sheet material substrate having a vapor phase corrosion inhibitor composition applied as a printed pattern of uniformly distributed spaced - areas of predetermined size occupying about 25% of the total area of the treated sheet and consisting of a total dried weight of about 0.226 to 0.302 grams of the inhibitor composition per square foot of the treated sheet.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
90 words
In an article for inhibiting corrosion of ferrous metal surfaces, a sheet carrier over-printed with a pattern of uniformly spaced areas of predetermined size formed of a vapor phase corrosion inhibiting composition applied with a printed density such that the dried weight of the said composition contained on each square foot of the printed area of the carrier is within the range of 0.2268 to 0.302 grams and the pattern of uniformly spaced inhibitor printed area occupies about 25 to 30 percent of each square foot of the printed carrier.
Claim 2
Dependent Claim
90 words
In an article for inhibiting corrosion of ferrous metal surfaces, a sheet carrier over-printed with a pattern of uniformly spaced areas of predetermined size formed of a vapor phase corrosion inhibiting composition applied with a printed density such that the dried weight of the said composition contained on each square foot of the printed area of the carrier is within the range of 0.2268 to 0.302 grams and the pattern of uniformly spaced inhibitor printed area occupies about 25 to 30 percent of each square foot of the printed carrier.
Claim 3
Dependent Claim
26 words
An article according to claim 1 wherein the dried weight of the said composition contained by each square foot of the printed carrier is 0.272 grams.
Claim 4
Dependent Claim
25 words
An article according to claim 1 wherein the inhibitor printed spaced area pattern occupies substantially 26.7 percent of each square foot of the printed carrier.
Claim 5
Dependent Claim
21 words
An article according to claim 3 wherein the inhibitor printed spaced-area pattern is composed of solid shapes of any suitable kind.
