Independent Claim
55 words
An animal collar having ectoparasiticidal activity, which comprises a plastic composition comprising from 75 to 98% by weight of a hydrophobic polyurethane which is not swellable in water and from 2 to 25% by weight of an ectoparasiticidal carbamate having a vapor pressure of from 10 -4 to 10 -6 mm Hg at 20° C.
Claim 2
Dependent Claim
55 words
An animal collar having ectoparasiticidal activity, which comprises a plastic composition comprising from 75 to 98% by weight of a hydrophobic polyurethane which is not swellable in water and from 2 to 25% by weight of an ectoparasiticidal carbamate having a vapor pressure of from 10 -4 to 10 -6 mm Hg at 20° C.
Claim 3
Dependent Claim
14 words
An animal collar according to claim 1 wherein the polyurethane is a thermoplastic polyurethane.
Claim 4
Dependent Claim
77 words
An animal collar comprising a member selected from the group consisting of a textile material, leather, imitation leather or a flexible plastic material, said material being impregnated and/or coated with a plastic composition comprising from 75 to 98% by weight of a hydrophobic polyurethane which is not swellable in water and from 2 to 25% by weight of an ectoparasiticidal carbamate having a vapor pressure of from 10 -4 to 10 -6 mm Hg at 20° C.
Claim 5
Dependent Claim
77 words
An animal collar comprising a member selected from the group consisting of a textile material, leather, imitation leather or a flexible plastic material, said material being impregnated and/or coated with a plastic composition comprising from 75 to 98% by weight of a hydrophobic polyurethane which is not swellable in water and from 2 to 25% by weight of an ectoparasiticidal carbamate having a vapor pressure of from 10 -4 to 10 -6 mm Hg at 20° C.
Claim 6
Dependent Claim
15 words
An animal collar according to claim 3, wherein the polyurethane is a cold-curing two-component system.
Claim 7
Independent Claim
70 words
A method of protecting or freeing an animal from ectoparasites which comprises fitting the animal with a collar having ectoparasiticidal activity, which comprises a plastic composition comprising from 75 to 98% by weight of a hydrophobic polyurethane which is not swellable in water and from 2 to 25% by weight of an ectoparasiticidal carbamate having a vapor pressure of from 10 -4 to 10 -6 mm Hg at 20° C.
Claim 8
Independent Claim
70 words
A method of protecting or freeing an animal from ectoparasites which comprises fitting the animal with a collar having ectoparasiticidal activity, which comprises a plastic composition comprising from 75 to 98% by weight of a hydrophobic polyurethane which is not swellable in water and from 2 to 25% by weight of an ectoparasiticidal carbamate having a vapor pressure of from 10 -4 to 10 -6 mm Hg at 20° C.

Independent Claim
89 words
A method of protecting or freeing an animal from ectoparasites which comprises fitting the animal with a collar comprising a member selected from the group consisting of a textile material, leather, imitation leather or a flexible plastic material, said material being impregnated and/or coated with a plastic composition comprising from 75 to 98% by weight of a hydrophobic polyurethane which is not swellable in water and from 2 to 25% by weight of an ectoparasiticidal carbamate having a vapor pressure of from 10 -4 to 10 -6 mm Hg.
Claim 10
Independent Claim
89 words
A method of protecting or freeing an animal from ectoparasites which comprises fitting the animal with a collar comprising a member selected from the group consisting of a textile material, leather, imitation leather or a flexible plastic material, said material being impregnated and/or coated with a plastic composition comprising from 75 to 98% by weight of a hydrophobic polyurethane which is not swellable in water and from 2 to 25% by weight of an ectoparasiticidal carbamate having a vapor pressure of from 10 -4 to 10 -6 mm Hg.
Claim 11
Dependent Claim
30 words
The animal collar of claim 1 wherein said plastic composition comprises from 85 to 95% by weight of said polyurethane and from 5 to 15% by weight of said carbamate.
Claim 12
Dependent Claim
31 words
