Abstract
Abstract A method for repelling animals and birds consists of applying to an area being protected a composition consisting essentially of an aqueous solution or dispersion of a carboxylated hydrophilic acrylic copolymer, a cross-linking agent for the carboxylated hydrophilic copolymer, a stabilizingly effective amount of an ultraviolet-absorbing agent and an animal or bird repelling compound.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
78 words
A method for repelling animals or birds from a grassy, wooded or paved area consisting of applying to a locus to be protected an animal- or bird-repelling amount of a composition consisting essentially of an aqueous solution or dispersion of a carboxylated hydrophilic acrylic copolymer, a cross-linking agent for the carboxyl of the carboxylated hydrophilic acrylic copolymer, and a stabilizingly effective amount of an ultraviolet-absorbing agent and an animal- or bird-repelling amount of an animal or bird repellant.
Claim 2
Independent Claim
78 words
A method for repelling animals or birds from a grassy, wooded or paved area consisting of applying to a locus to be protected an animal- or bird-repelling amount of a composition consisting essentially of an aqueous solution or dispersion of a carboxylated hydrophilic acrylic copolymer, a cross-linking agent for the carboxyl of the carboxylated hydrophilic acrylic copolymer, and a stabilizingly effective amount of an ultraviolet-absorbing agent and an animal- or bird-repelling amount of an animal or bird repellant.
Claim 3
Dependent Claim
27 words
The method of claim 1, wherein the composition contains from about 0.0005% to about 0.30% by weight of the aqueous solution or dispersion of the ultraviolet-absorbing agent.
Claim 4
Dependent Claim
18 words
The method of claim 1, wherein the ultraviolet-absorbing agent absorbs from about 2700 A to about 3300 A.
Claim 5
Dependent Claim
29 words
The method of claim 1, wherein the carboxylated hydrophilic acrylic copolymer and the cross-linking agent together comprise from about 3% to about 30% of the aqueous solution or dispersion.
Claim 6
Dependent Claim
21 words
The method of claim 1, wherein the aqueous solution or dispersion is applied at a rate of 1-10 gallons per acre.
Claim 7
Dependent Claim
40 words
The method of claim 1, wherein the carboxylated acrylic copolymer contains monomer units from at least one C 1 -C 4 alkyl acrylate or methacrylate and from about 5% to about 20% by weight of at least one carboxylic monomer.
Claim 8
Dependent Claim
39 words
The method of claim 1, wherein the carboxylated hydrophilic acrylic copolymer contains monomer units from at least one C 1 -C 4 alkyl acrylate or methacrylate and from about 5% to about 20% by weight of acrylic acid monomer.
Claim 9
Dependent Claim
22 words
The method of claim 1, wherein the cross-linking agent is a diglycidyl or triglycidyl ether or a low molecular weight epoxy resin.
Claim 10
Dependent Claim
19 words
The method of claim 1, wherein the cross-linking agent is a methylolated melamine or low molecular weight melamine-formaldehyde resin.
Claim 11
Dependent Claim
17 words
The method of claim 1, wherein the cross-linking agent is a multivalent inorganic salt, oxide or hydroxide.
Claim 12
Dependent Claim
19 words
The method of claim 1, wherein the cross-linking agent is zinc oxide, zinc carbonate or an ammoniacal complex thereof.
Claim 13
Dependent Claim
38 words
The method of claim 1, wherein the cross-linking agent is mixed with the aqueous solution or dispersion of carboxylated hydrophilic acrylic copolymer and the animal- or bird-repellant and ultraviolet-absorbing agent immediately before application to the locus being protected.
Claim 14
Dependent Claim
40 words
The method of claim 1, wherein the amount of ultraviolet-absorbing agent is from about 0.0005% to about 0.30% by weight of the aqueous solution or dispersion and wherein the ultraviolet-absorbing agent absorbs from about 2700 A to about 3300 A.
Claim 15
Dependent Claim
24 words
The method of claim 1, wherein the animal- or bird-repelling composition also contains a herbicide, fungicide, insecticide, nematocide, plant growth regulator, fertilizer or colorant.
Claim 16
Dependent Claim
55 words
The method of claim 1, wherein the carboxylated hydrophilic acrylic copolymer contains monomer units from about 56% by weight of methyl methacrylate, about 30% by weight of ethyl methacrylate and about 14% by weight of acrylic acid, wherein the cross-linking agent is a diglycidyl or triglycidyl ether and wherein the ultraviolet-absorbing agent is 2-ethoxyethyl p-methoxycinnamate.
Claim 17
Dependent Claim
19 words
The method of claim 1, wherein the amount of animal- or bird-repellant is 0.5-5% by weight of the dispersion.
Claim 18
Dependent Claim
12 words

Claim 19
Dependent Claim
13 words
The method of claim 1, wherein the animal repellant is bone tar oil.
Claim 20
Dependent Claim
12 words

Claim 23
Dependent Claim
30 words
The method of claim 1, wherein the carboxylated hydrophilic acrylic copolymer contains monomer units from about 90% by weight of ethyl acrylate and about 10% by weight of acrylic acid.
Claim 24
Dependent Claim
20 words
The method of claim 22, wherein the cross-linking agent is glycerine triglycidyl ether and the ultraviolet-absorbing agent is 2-ethoxyethyl p-methoxycinnamate.
