Abstract
Abstract An improved method for inhibiting fungal (e.g., mold) growth formation in an organic coating, e.g., emulsion latex paint, exposed to fungi growing conditions is disclosed. The improvement comprises utilizing in said coating an amount effective (e.g., from about 0.03% to about 1.0% percent by weight of the coating) to inhibit fungal growth of an aluminum salt of acrylic acid.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
40 words
A METHOD FOR THE CONTROL OF FUNGI IN AN EMULSION-TYPE LATEX PAINT EXPOSED TO CONDITIONS WHICH PROMOTE FUNGAL GROWTH FORMATION WHICH METHOD COMPRISES UTILIZING IN SAID PAINT AN AMOUNT EFFECTIVE TO CONTROL FUNGI OF AN ALUMINUM SALT OF ACRYLIC ACID.
Claim 2
Independent Claim
40 words
A METHOD FOR THE CONTROL OF FUNGI IN AN EMULSION-TYPE LATEX PAINT EXPOSED TO CONDITIONS WHICH PROMOTE FUNGAL GROWTH FORMATION WHICH METHOD COMPRISES UTILIZING IN SAID PAINT AN AMOUNT EFFECTIVE TO CONTROL FUNGI OF AN ALUMINUM SALT OF ACRYLIC ACID.
Claim 3
Dependent Claim
33 words
The method of claim 1 wherein said aluminum salt of acrylic acid is present in said coating in an amount of from about 0.03 to about 1.0 percent by weight of the coating.
Claim 4
Dependent Claim
30 words
The method of claim 2 wherein said aluminum salt of acrylic acid is present in an amount of from about 0.05 to about 0.2 percent by weight of the coating.
Claim 5
Dependent Claim
34 words
A fungal growth inhibiting composition comprising an emulsion-type latex paint which is adapted to promote fungi growth therein and a minor amount of an aluminum salt of acrylic acid effective to inhibit fungal growth.
Claim 6
Dependent Claim
34 words
A fungal growth inhibiting composition comprising an emulsion-type latex paint which is adapted to promote fungi growth therein and a minor amount of an aluminum salt of acrylic acid effective to inhibit fungal growth.
Claim 7
Dependent Claim
33 words
The composition of claim 4 wherein said aluminum salt of acrylic acid is present in said coating in an amount of from about .03 to about 1.0 percent by weight of the coating.
Claim 8
Dependent Claim
45 words
A mold inhibiting composition adapted to be utilized in mold growth promoting conditions, said composition comprising an organic paint susceptible to the growth of fungi therein, said paint containing therein a minor amount effective to inhibit mold growth of an aluminum salt of acrylic acid.
Claim 9
Dependent Claim
45 words
A mold inhibiting composition adapted to be utilized in mold growth promoting conditions, said composition comprising an organic paint susceptible to the growth of fungi therein, said paint containing therein a minor amount effective to inhibit mold growth of an aluminum salt of acrylic acid.
Claim 10
Dependent Claim
58 words
In an organic coating material susceptible to the growth of fungi therein, the improvement which comprises incorporating in said organic coating material selected from the group consisting of naturally occuring coating materials, varnishes, oil stains, epoxy resin base coatings, polyurethanes, and alkyd resin coatings an amount effective to inhibit fungi growth of an aluminum salt of acrylic acid.
