Definitions

  • composition for the impregnation of fibers, fabrics and nettings imparting a protective activity against pests
  • the present invention relates to an insecticide composition for application to a nonliving material, which insecticide composition comprises a mixture including at least one N-arylhydrazine derivative, and at least one polymeric binder; an impregnated nonliving material comprising at least one N-arylhydrazine derivative, and at least one polymeric binder; a process for impregnation of a non-living material, a process for coating of a non-living material and the use of the insecticide composition of the present invention for impregnation of a non-living material.
  • Infectious diseases cause huge damages by debilitating or even killing humans and animals in many countries, especially in tropical countries.
  • Many of these diseases e.g. malaria, dengue and yellow fever, lymphatic filariasis, and leishmaniasis
  • insects Since many medical methods like vaccination or medical treatments are either impossible or too expensive or have been rendered ineffective due to spreading resistance against drugs, efforts have been concentrated on controlling the transmitting insects.
  • Methods to control these insects comprise treating surfaces of huts and houses, air spraying and impregnation of curtains and bednets. The latter treatment is up to now mostly done by dipping the textile material into emulsions or dispersions of insecticides or spraying them onto the nets.
  • WO 01/37662 discloses impregnated nettings or fabrics for insect or tick killing and/or repellent of an insect or tick comprising an insecticide and/or a repellent, and a film forming component reducing the wash off and degradation of the insecticide compo- nent from the netting or fabric by forming a water- and optionally an oil-resistant film.
  • the film forming component preferably comprises one or more components selected from paraffin oil or wax derivatives, silicon derivatives, silicon oils or wax derivatives, and polyfluorocarbon derivatives.
  • the netting or fabric is impregnated by adding a solu- tion or a water emulsion of an insecticide and/or repellent and a film forming component successively (in two steps) or in one process step.
  • WO 01/37662 is the insecticide and/or repellent dissolved in an organic solvent in the process for impregnation of a fabric or a netting.
  • Preferred insecticides are according to WO 01/37662 from the group of pyrethroid compounds.
  • WO 03/034823 discloses an insecticide composition for application to a fabric material, which composition comprises a mixture including an insecticide, a copolymeric binder, that, after drying and while the fabric material is dry, imparts hydrophobicity to the insecticide, and a dispersing agent, that, after application of the composition to a fabric and upon wetting the fabric, reduces the hydrophobicity imparted to the insecticide by the binder to permit limited insecticide release.
  • the copolymeric binder is prepared as a copolymer emulsion that is derived by an emulsion polymerization technique from monomers selected from at least one of the groups including a) vinyl esters of aliphatic acid having 1 to 18 carbon atoms, such as vinyl acetate and vinyl versatate; b) acrylic and methacrylic esters of an alcohol having 1 to 18 carbon atoms, such as butyl acry- late, 2-ethylhexylacrylate, and methyl acrylate; and c) mono- and di-ethylenically unsaturated hydrocarbons, such as styrene, and aliphatic diens, such as butadiene.

  • the preferred copolymeric binder is prepared by emulsion polymerisation of two different monomers.
  • the insecticide composition of WO 03/034823 is applied to the fabric or netting by dipping, spraying, brushing, and the like. According to the examples the insecticides have to be dissolved in organic solvents before applying the insecticide composition to a fabric material.
  • Suitable insecticides are according to WO 03/034823 pyrethroids and non-pyrethroids such as Carbosulphan.
  • US 5,631 ,072 discloses the manufacture of fabric intended to be made into washable garments, more specifically to the placement of an insecticide such as permethrin in the fabric by impregnation with polymeric binders and a cross-linking agent, or by surface coating with a polymeric binder and a thickening agent to improve the efficiency as an insect repellent and retention of the permethrin in the fabric as an effective insec- ticide through successive washings of the garments.
  • suitable binders are acrylic binders and polyvinylacetate binders, which are not further specified.
  • the amount of insecticide in the solutions for impregnation of the fabric is very high (1250 mg insecticide per m 2 ).
  • pyrethroid As insecticide permethrin, a synthetic pyrethroid, is used.
  • Typical problems arising with the use of presently available public health pest control agents such as pyrethroids are e.g. resistance of pests or unfavorable environmental or toxicological properties.
  • Another problem encountered concerns the need to have available public health pest control agents which are effective against a broad spectrum of public health pests.

Composition for the impregnation of fibers, fabrics and nettings imparting a protective activity against pests
Description
The present invention relates to an insecticide composition for application to a nonliving material, which insecticide composition comprises a mixture including at least one N-arylhydrazine derivative, and at least one polymeric binder; an impregnated nonliving material comprising at least one N-arylhydrazine derivative, and at least one polymeric binder; a process for impregnation of a non-living material, a process for coating of a non-living material and the use of the insecticide composition of the present invention for impregnation of a non-living material.
Infectious diseases cause huge damages by debilitating or even killing humans and animals in many countries, especially in tropical countries. Many of these diseases (e.g. malaria, dengue and yellow fever, lymphatic filariasis, and leishmaniasis) are transmitted by insects. Since many medical methods like vaccination or medical treatments are either impossible or too expensive or have been rendered ineffective due to spreading resistance against drugs, efforts have been concentrated on controlling the transmitting insects. Methods to control these insects comprise treating surfaces of huts and houses, air spraying and impregnation of curtains and bednets. The latter treatment is up to now mostly done by dipping the textile material into emulsions or dispersions of insecticides or spraying them onto the nets. Since this provides only a loose adhesion of the insecticide molecules on the surface of the fibers, this treatment is not wash-permanent and has to be repeated after each washing. Studies have proven long-lasting insecticide-treated nets (LLINs) to be more reliable in preventing carrier-borne diseases in comparison with conventional nets, which have to be re- impregnated with insecticide after each washing. Experience shows, however, that washed nets are not re-treated in many cases leaving them without any biological ac- tivity. WHO, UNICEF and global relief organisations therefore recommend pre-treated, long-lasting insecticide-treated nets which are wash-permanent as an effective means for the containment of deadly tropical diseases, especially malaria and dengue fever. This is not only comfortable for the user but gives him an economic advantage as well, saving the costs for the repeated impregnation. It is an ecological advantage as well, since the permanent treatment is done under controlled conditions in textile finishing plants.
WO 01/37662 discloses impregnated nettings or fabrics for insect or tick killing and/or repellent of an insect or tick comprising an insecticide and/or a repellent, and a film forming component reducing the wash off and degradation of the insecticide compo- nent from the netting or fabric by forming a water- and optionally an oil-resistant film. The film forming component preferably comprises one or more components selected from paraffin oil or wax derivatives, silicon derivatives, silicon oils or wax derivatives, and polyfluorocarbon derivatives. The netting or fabric is impregnated by adding a solu- tion or a water emulsion of an insecticide and/or repellent and a film forming component successively (in two steps) or in one process step. According to the specification of WO 01/37662 is the insecticide and/or repellent dissolved in an organic solvent in the process for impregnation of a fabric or a netting. Preferred insecticides are according to WO 01/37662 from the group of pyrethroid compounds.
WO 03/034823 discloses an insecticide composition for application to a fabric material, which composition comprises a mixture including an insecticide, a copolymeric binder, that, after drying and while the fabric material is dry, imparts hydrophobicity to the insecticide, and a dispersing agent, that, after application of the composition to a fabric and upon wetting the fabric, reduces the hydrophobicity imparted to the insecticide by the binder to permit limited insecticide release. The copolymeric binder is prepared as a copolymer emulsion that is derived by an emulsion polymerization technique from monomers selected from at least one of the groups including a) vinyl esters of aliphatic acid having 1 to 18 carbon atoms, such as vinyl acetate and vinyl versatate; b) acrylic and methacrylic esters of an alcohol having 1 to 18 carbon atoms, such as butyl acry- late, 2-ethylhexylacrylate, and methyl acrylate; and c) mono- and di-ethylenically unsaturated hydrocarbons, such as styrene, and aliphatic diens, such as butadiene. The preferred copolymeric binder is prepared by emulsion polymerisation of two different monomers. The insecticide composition of WO 03/034823 is applied to the fabric or netting by dipping, spraying, brushing, and the like. According to the examples the insecticides have to be dissolved in organic solvents before applying the insecticide composition to a fabric material. Suitable insecticides are according to WO 03/034823 pyrethroids and non-pyrethroids such as Carbosulphan.
US 5,631 ,072 discloses the manufacture of fabric intended to be made into washable garments, more specifically to the placement of an insecticide such as permethrin in the fabric by impregnation with polymeric binders and a cross-linking agent, or by surface coating with a polymeric binder and a thickening agent to improve the efficiency as an insect repellent and retention of the permethrin in the fabric as an effective insec- ticide through successive washings of the garments. According to the examples, suitable binders are acrylic binders and polyvinylacetate binders, which are not further specified. The amount of insecticide in the solutions for impregnation of the fabric is very high (1250 mg insecticide per m2). As insecticide permethrin, a synthetic pyrethroid, is used. Typical problems arising with the use of presently available public health pest control agents such as pyrethroids are e.g. resistance of pests or unfavorable environmental or toxicological properties. Another problem encountered concerns the need to have available public health pest control agents which are effective against a broad spectrum of public health pests. Accordingly, there is a need to provide a new and improved ways of public health pest control It is an object of the present invention to provide an insecticide composition (in the following also: composition) for application to a non-living material, wherein the public health pest control agent is not washed out and in which the bioavailability of the public health pest control agent for killing insects is maintained after multiple washes or multiple contacts with water.lt is a further object of the present invention to provide a composition comprising alternative public health pest control agents, preferably exhibiting an enhanced pesticidal spectrum of action.
It is a further object of the present invention to provide impregnated and/or coated non- living materials comprising atemative public health pest control agents which are not washed out and in which the bioavailability of the public health pest control agent for killing insects is maintained after multiple washes or multiple contacts with water.
According to the present invention there is provided an insecticide composition for ap- plication to a non-living material which composition comprises a mixture including

The N-arylhydrazine derivatives of formula I of the insecticide compositions of the present invention are known from and can be prepared according to preparation methods described or referenced in EP-A 604 798. This document relates to plant protection in the agricultural field and discloses the insecticidal and acaricidal activity of compounds of fomula I and other compounds against crop pests of the Coleoptera, Lepidoptera and Acarina orders.
Further, the use of the N-arylhydrazine derivatives of formula I for combating non-crop pests is disclosed in application PCT/EP/04/013687 having the title " The use of N- arylhydrazine derivatives for combating pests" which has been filed on December 2, 2004, which is fully incorporated by reference.
Activity of a compound against pests for plant protection in the agricultural field, that is, against crop pests, does not generally suggest activity of that compound against public health pests. Crop pest control always is a part of plant protection. Public health pest control, on the contrary, relates to protection of non-living organic materials, or hygiene and disease prevention.
It has now been found that a certain group of N-arylhydrazines, namely the compounds of formula I, exhibit broad spectrum activity against public health pests. It has further been found that insecticide compositions comprising component A (at least one N- arylhydrazine derivative of formula I) as well as component B (at least one polymeric binder) provide a very good wash resistance while permitting a continuous release of the N-arylhydrazine derivative at a controlled rate.
The insecticide composition of the present invention may be in form of a solid or an aqueous formulation, wherein the aqueous formulation is preferred.
The insecticide composition of the present application provides wash resistance while permitting continuous release of the N-arylhydrazine derivative at a controlled rate, in order to provide the required bioavailability of the N-arylhydrazine derivative. Further, the insecticide emission to the environment is decreased by using the composition of the present invention which is applied to a non-living material.
In the context of the present invention the non-living material is preferably a textile material or plastics material selected from the group consisting of yarn, fibers, fabric, knit- goods, nonwovens, netting material, foils, tarpaulins and coating compositions. The netting material may be prepared by any method known in the art, for example by circular knitting or warp knitting, or by sewing parts of a netting to obtain the desired net- tings.
The textile material or plastics material may be made form a variety of natural and synthetic fibers, also as textile blends in woven or non-woven form, as knit goods, yarns or fibers. Natural fibers are for example cotton, wool, silk, jute or hamp. Synthetic fibers are for example polyamides, polyesters, polyacryl nitriles, polyolefines, for example polypropylene or polyethylene, Teflon, and mixtures of fibers, for example mixtures of synthetic and natural fibers. Polyamides, polyolefins and polyesters are preferred. Polyethylene terephthalate is especially preferred.

The nettings are for example used as bed nets for example mosquito nets, or for covering or as nets in agriculture and viniculture. Other applications are movable fences for the protection of humans and animals against air-borne low-flying insects. Fabrics or nettings may be used for packages, wrapping sacks, containers for food, seeds and feed thus protecting the material from attack by insects but avoiding direct contact with the insecticide- treated nets or fabrics.
Treated foils or tarpaulins can be used on all human premises which are permanently or temporarily inhabited such as refugee camps.
It is further possible to use the treated nettings in dwellings having mud walls. A treated netting is pressed into a fresh, wet wall mud before it dries. The mud will ooze into the holes in the net but the yarn of the net will not be covered. When this wall covering is dried the insecticide and/or repellent of the treated net is slowly released and can repell or kill pests that come into contact with the wall.
Further, the non-living material may be in the form of cellulose-containing materials e.g. wooden materials such as houses, trees, board fences, or sleepers and also paper; and also construction materials, furniture, leathers, animal, plant and synthetic fibers, vinyl articles, electric wires and cables .
The insecticide composition of the present invention is particularly suitable for application to polyester nettings as used for mosquito nets.
The insecticide composition of the present invention may be applied to the non-living material, for example to textile material or plastics material, before their formation into the desired products, i.e. while still a yarn or in sheet form, or after formation of the desired products.

The acrylic binder of the present invention is preferably obtainable by emulsion polymerization of the monomers mentioned before. Suitable process conditions are known by a person skilled in the art.
The monomers are polymerized under usual conditions of temperature and pressure, i.e. at from atmospheric pressure to 10 bar and in general at temperatures of from 20 to 100 0C, preferably 50 to 85 0C, depending on the initiator used. Usually the polym- erization is carried out in a stirred reaction vessel under an inert atmosphere.
The copolymerization is generally carried out in water. However, it is also possible to add before, within or after the polymerization process up to 80 % by weight, relating to the aqueous phase, of a lower alcohol like methanol, ethanol or isopropanol or a lower ketone like acetone. Preferably the copolymerization is carried out in water without addition of further solvents.
The polymerization process may be carried out continuously or batch-wise, and it is possible to employ the usual methods of batch-wise polymerization, e.g. mixing all po- lymerization components at once or feeding emulsified monomers and catalysts from one or more metering vessels to a batch containing a portion of a monomer. It is possi- ble to add polymer seed to the polymerization mixture to adjust the particle size of the emulsion polymers obtained.
The emulsion polymerization is preferably carried out in the presence at least one ini- tiator which form radicals under the polymerization conditions. Suitable initiators are for example all common peroxy compounds or azo compounds.
Suitable peroxides are for example alkali metal peroxodisulfates, for example sodium peroxodisulfate, ammonium peroxodisulfate; hydrogen peroxide; organic peroxides, for example diacetyl peroxide, di-tert-butyl peroxide, diamylperoxide, dioctanoyl peroxide, didecanoyl peroxide, dilauroyl peroxide, dibenzol peroxide, bis-(o-toloyl)peroxide, suc- cinyl peroxide, tert-butyl peracetate, tert-butyl permaleinate, tert-butyl perpivalate, tert- butylperoctoate, tert-butyl perneodecanoate, tert-butyl perbenzoate, tert-butyl peroxide, tert-butyl hydroperoxide, cumene hydroperoxide, tert-butyl-peroxy-2-ethylhexanoate, and diisopropyl peroxodicarbamate. Further suitable initiators are azo compounds, for example azobis isobutyronitrile, anzobis(2-amidopropane)dihydrochloride, and 2,2'-azobis(2-methylbutyronitrile).
The initiators are added in usual amounts, for example in an amount of 0.05 to 5 % by weight, preferably 0.05 to 2 % by weight, based on the total weight of monomers.
If the polymerization is carried out at low temperature, use may be made of conventional redox catalysts. For example, it is possible to use, in addition to the peroxide catalysts of the above kinds, from 0.05 to 2 % by weight, based on the total of mono- mers, of reducing agents such as hydrazine, soluble oxidizable sulfoxy compounds such as alkali metal salts of hydrosulfites, sulfoxylates, thiosulfates, sulfites, and bisul- fites, which may be optionally activated by the addition of traces of heavy metals, e.g. salts of Ce, Mo, Fe, and Cu, in the usual manner. Preferred redox catalysts are redox catalysts of acetone disulfite and organic peroxides like tert-C4Hg-OOH; Na2S2O5 and organic peroxides like tert-C4-Hg-OOH; or HO-CH2SO2H and organic peroxides like tert-C4Hg-OOH. Further preferred are redox catalysts like ascorbic acid and hydrogen peroxide.
The initiator may be added completely at the beginning of the polymerization, but it is also possible to add the initiator in the course of the emulsion polymerization process in a continuous or stepwise way. The way of adding the initiator is known in the art.
The polymerization process is carried out until a conversion of at least 95 % by weight of the monomers is reached. For removal of the residual monomer at the end of the emulsion polymerization initiator may be added for chemical deodoration. The emulsion polymerization is carried out by adding emulsifiers or mixtures of emulsi- fiers known in the art. The emulsifiers generally used are ionic (anionic or cationic) and/or non-ionic emulsifiers such as polyglycolethers, sulfonated paraffin hydrocarbons, higher alkylsulfates such as oleyl amine, lauryisulfate, alkali metal salts of fatty acids such as sodium stearate and sodium oleate, sulphuric acid esters of fatty alcohols, ethoxylated C8-i2-alkylphenols, usually having from 5 to 30 ethylene oxide radicals, and their sulfonation products, and also sulfosuccinic acid esters. The emulsifier or mixtures of emulsifiers are usually employed in an amount of 0.05 to 7 % by weight, preferably 0.5 to 4 % by weight, based on the total weight of monomers.
In some cases there is added a co-solvent or a mixture of co-solvents to the emulsifiers. Preferred co-solvents are aliphatic d- to C3o-alcohols which are linear or branched, alicyclic C3- to C3o-alcohols and mixtures thereof. Examples are n-butanol, n-hexanol, cyclohexanol, 2-ethylhexanol, i-octanole, n-octanole, n-decanole, n- dodecanole, stearyl alcohol, oleyl alcohol or cholesterol. Further possible co-solvents are alkane diol, ethylene glycol alkyl ethers, N-alkyl pyrrolidones, and N-alkyl and N1N- dialkyle acid amides like ethylene glycol monobutyl ether, diethylen glycol monoethyl ether, tetraethylen glycol dimethyl ether, N-methyl pyrrolidone, N-hexyl pyrolidone, diethyl acid amide or N-octyl acid amide. The co-solvents or mixture of co-solvents is added in an amount of 0 to 20 % by weight, preferably 1 to 5% by weight.
In many cases use is also made of a protective colloid, examples of which are polyvinyl alcohol, partially saponified polyvinyl acetates, cellulose derivatives, copolymers of methyl acrylate with acrylic amide and methylacrylic amide or vinyl pyrrolidine polymers in amounts of from 0.5 to 10 % by weight and in particular 1.0 to 5 % by weight of the weight of the monomers.
Further, it is possible to add in general up to 10 % by weight, preferably 0.05 to 5 % by weight of mono- or di-olefinically unsaturated monomers containing reactive or cross- linking groups. Examples of such monomers are in particular the amides of α ,β - olefinically unsaturated C3-5-carboxylic acids, particularly acryl amides, methacryl amides and maleic diamides, and their N-methylol derivatives such as N-methylol acrylic amide, N-methylol methacrylic amide, N-alkoxy methyl amides of α,β -monoolefinically unsaturated C3-s-carboxylic acids such as N-methoxy methacrylic amide and N-n- butoxymethylacrylic amide, vinyl sulfonic acid, monoesters of acrylic and methacrylic acids with alkanediols such as glycol, butanediol-1 ,4, hexane diol-1,6, and 3- chloropropanediol-1 ,2, and also allyl and methallyl esters of α,β-olefinically unsaturated mono- and di-carboxylic acids such as diallyl maleate, dimethyl allyl fumarate, allyl acrylate and allyl methacrylate, diallyl phthalate, diallyl terephthalate, p-di-vinyl ben- zene, methylene-bis-acrylamide and ethylene glycol di-allylether. The solids content of the aqueous dispersions of polymers obtained in the emulsion polymerization is usual 15 to 75 % by weight, preferably 25 to 50 % by weight. To obtain high space time yields of the reactor dispersions having a high solids content are preferred. To obtain solids contents of more than 60 % by weight a bi- or polymodal particle distribution should be adjusted, because otherwise it is not possible to handle the dispersion, because of the high viscosity. New particle generations (for obtaining bi- or polymodel particle size distributions) are for example formed by addition of seed (EP-A 0 810 831), addition of an excess of emulsifier or addition of mini-emulsions. The formation of new particle generations may be carried out at any time and is de- pending on the desired particle size distribution for a low viscosity.
The molecular weight of the non crosslinked emulsion polymers obtained is in general 40,000 to 250,000 (determined by GPC). The molecular weight is usually controlled by the use of conventional chain stoppers in conventional amounts. Conventional chain stoppers are for example sulfoorganic compounds.
The acrylic binder of the present invention is obtained in form of its aqueous dispersion and is preferably employed in the insecticide compositions of the present invention in form of the aqueous dispersion.

The aqueous formulation or the melt preferably comprises the insecticide composition as disclosed in the present invention, which is preferably employed in form of an aqueous formulation.
In the context of the present invention "impregnation" is a process for applying the insecticide composition. This process may include a process for curing the applied insecticide composition to achieve a coating onto the non-living material, if desired. An "impregnated non-living material" is a material onto which the insecticide composition is applied. The "impregnated non-living material" may be coated by curing the applied insecticide composition, if desired.
The insecticide composition of the present invention may also be applied onto the nonliving material by transfer printing, inkjet printing, a screen process, and powder print- ing.
Suitable non-living materials are mentioned before. It is possible to impregnate the non-living material, for example the textile or plastics material, in form of its finished product (end of line treatment, discontinuous treatment). In this case no further pass is necessary after impregnation. However, it is also possible to impregnate the non-living material, for example the textile or plastics material, in form of a yarn or fibers, which have to be further processed after impregnation to obtain the desired finished product (in line treatment). Preferred N-arylhydrazine derivatives of formula I used are also defined before as well as preferred polymeric binders.
The discontinuous treatment may be performed in factories, in local treatment centers (local factories) or even with mobile equipment which is e.g. mounted on trucks or pickups (e.g. in re-treatment antimalaria campaigns). The discontinuous treatment may be done on new (untreated non-living materials, for example textile materials or plastics materials, preferably nettings, in use or made-up form (preferably as nets)) or on used non-living materials, for example textile materials or plastics materials (preferably nets), preferably after washing.
It is one advantage of the present invention that the impregnation is carried out in an aqueous formulation or in a melt. It is not necessary to add any organic solvents. In a preferred embodiment of the present invention the treatment bath is an aqueous formulation which does not comprise any further solvents, especially no organic solvents.
It is advantageous to avoid the use of organic solvents because the non-living material, for example the textile material or plastics material of the present invention may be used in close contact to the human body. The non-living material, for example textile material or plastics material, impregnated by the method of the present invention does not comprise any organic solvent residue which is beneficial both from a human toxico- logical and an ecological point of view.
The aqueous formulation or the melt employed in the impregnation process may further comprise one or more ingredients selected from the group consisting of preservatives, detergents, stabilisers, agents having UV-protecting properties, spreading agents, anti- migrating agents, foam-forming agents, wetting agents, anti-soiling agents, thickeners, further biocides, plasticizers, adhesive agents, fragrance, pigments and dyestuffs.
In a further embodiment the aqueous formulations or the melts employed for impregnation of the non-living material comprise in addition to the at least one N-arylhydrazine derivative of formula I and the at least one polymeric binder at least one pigment and/or at least one dyestuff. These aqueous formulations or melts are suitable for impregnation of the non-living material with at least one N-arylhydrazine derivative and additionally coloring the non-living material at the same time. Many of the non-living material which are impregnated with at least one N-arylhydrazine derivative are preferably colored. With the process of the present invention it is possible to color and im- pregnate the non-living material with an N-arylhydrazine derivative at the same time. The method of the present invention is therefore very economical, because the coloring and impregnation with an N-arylhydrazine derivative is carried out in one step.
In a further embodiment of the present invention the present invention therefore relates to a process for impregnation of a non-living material as described before, wherein the dyeing of the non-living material is carried out simultaneously with the impregnation of the non-living material, wherein an aqueous formulation is formed further comprising at least one dyestuff and/or at least one pigment.
Suitable amounts of pigments are in general 0.01 to 20 % by weight, preferably 0.1 to 10 % by weight, more preferably 0.2 to 5 % by weight, based on the weight of the aqueous formulation used for impregnation. Suitable dyestuffs are employed in general in an amount of from 0.01 to 20 % by weight, preferably 0.1 to 10 % by weight, more preferably 0.2 to 5 % by weight, based on the weight of the aqueous formulation used for impregnation.
Step i) Forming an aqueous formulation comprising at least one N-arylhydrazine derivative of formula I and at least one polymeric binder and optionally further ingredients
The aqueous formulation is formed by mixing all ingredients necessary for impregnation of the non-living material with water. The aqueous formulation is generally formed at temperatures of from 10 to 70 0C, preferably 15 to 50 0C, more preferably 20 to 40 0C. Suitable aqueous formulations comprise an insecticide composition for application to a non-living material as described in the present invention.
Step H) Applying the aqueous formulation comprising at least one N-arylhydrazine derivative of formula I and at least one polymeric binder and optionally further ingredients to the non-living material
Step Ha)
The insecticide composition is applied by passing the non-living material through the aqueous formulation. This step is known by a person skilled in the art as padding. In a preferred embodiment the non-living material is completely submerged in the aqueous treatment liquor (aqueous formulation) either in a trough containing the liquor or passed through the treatment bath (aqueous formulation) which is held between two horizontally oriented rollers.
In accordance with the invention, the non-living material may either be passed through the aqueous formulation or the aqueous formulation may be passed through the nonliving material. These processes are preferred for impregnating open-width material, especially textile or plastics material, which is later tailored into nets. For small-scale production or re-impregnating of non-treated nets, use of a simple hand-held roller might be sufficient.
Step lib)
It is further possible to apply the aqueous formulation onto the non-living material by one-side only-coating applications methods. Suitable one-side only-coating application methods are for example knife-/doctor-blade-coating, roller coating or screen-printing. By this methods it is possible to impregnate only one side of the non-living material which is advantageous, if e.g. direct contact of the human skin with insecticide-treated material is to be avoided.
Knife-/doctor-blade-coating systems are for example knife-over-air-systems, knife-over- roller systems, knife-over-table systems or knife-over-rubber-belt systems. Further knife coating systems are for example commabar or Mayerbar knife systems.
Roller-coating systems are for example kiss-coating systems with one, two, three or more rollers, reverse-roll-coater systems and raster roll systems. In these roller-coating systems at least one roller is partly dipped into the aqueous formulation thus applying the aqueous formulation to the side of the non-living material in contact with the roller (kiss-rolling).
Screen-printing systems are for example rotary-screen printing systems and flat-screen printing systems. With these applications methods a dot coating or a full-surface coating can be applied to the non-living material, for example by using an additional whisper-blade behind the rotary-screen.
A person skilled in the art will adjust the viscositiy of the aqueous formulation used by applying thickeners where appropriate.
Step Hc)
It is further possible to apply the aqueous formulations to the non-living material by double-side coating application methods, for example double-side knife-coating systems, foulard with two air-knifes or foulard with squeezing rollers.
By using the double-side-knife-coating system or by passing two times through a one- side-only coating system, it is possible to apply the aqueous formulation only to the surfaces of both sides of the non-living material and thus to reduce the quantitiy of the aqueous formulations needed for a certain effect.
Step Hd) and step He)
It is further possible to apply the aqueous formulation by spraying the solution or emulsion onto the non-living material. Further it is possible, to apply the emulsion in the form of a foam which is applied to the non-living material. A foam comprises less water than the solution or emulsion mentioned above. The drying process may therefore be very short. Step Hf), Hg) and step Hh)
It is further possible to apply the aqueous formulation onto the non-living material by submerging the non-living material into the aqueous formulation, brushing the aqueous formulation onto or into the non-living material, or pouring the aqueous formulation onto the non-living material. Said methods are known by a person skilled in the art.
Impregnation of the non-living material in step iia), iib), iic), iid), iie), iif), iig), or iih) is carried out at temperatures of in general from 10 to 70 0C, preferably 15 to 50 0C, more preferably 20 to 40 0C.
Step Hi) Optionally removing the surplus aqueous formulation
The surplus aqueous formulation is usually removed by squeezing the non-living mate- rial, for example the textile material or plastics material , preferably by passing the nonliving material rollers as known in the art, preferably by means of doctor blade, thus achieving a defined liquor uptake. The squeezed-off liquor is usually re-used.
The surplus aqueous formulation may alternatively be removed by centrifuging or vac- uum suction.
Step iv) Drying and/or curing the non-living material
The drying is in general carried out temperatures below 200 0C. Preferred tempera- tures are from 50 to 170 °C, more preferably from 70 to 150 0C. The temperature choice is a function of the evaporation temperature and mobility of the insecticide in the formulation.
It should be noted that the drying process may be a passive drying as the process may be carried out in rather hot climates. An active drying process would normally be performed during high scale processing.
After or simultaneously to the drying, the impregnated non-living material is optionally finally cured and/or fixated. A person skilled in the art knows how to carry out a curing and/or fixation. The curing process is in general carried out at a temperature which may be higher than the drying temperature. Preferred temperatures for curing are 60 to 170 0C, preferably 70 to 170 0C, more preferably 80 to 150 0C. Drying and curing can be advantageously be performed during one single process, e.g. in stenters with different compartments which can be heated to different temperatures. If a reactive crosslinking agent is used temperatures may be lower, e.g. 30 to 1300C, preferably 30 to 1000C. The drying and/or curing may for example be achieved in any equipment usually applied in non-living mills for these purposes, such as stenters, loop dryers, hotflues, tumble dryers, pad steam machines etc. In one embodiment of the present invention, equipment for continuous drying and/or curing is applied. In another embodiment of the present invention, equipment for discontinuous (batch-wise) drying and/or curing is used. Such equipment may comprise rotary or tumble dryers used in professional laundries, combined laundry/dryers which may be heated to the treatment temperatures, e.g. jeans stone-wash. The treatment chemicals may be added as a liquid or be sprayed onto the netting material and then brought to a homogeneous distribution by rotating the wet material before or during drying/curing. The treatment liquor may be added in excess if it is possible to remove the excess liquor e.g. by centrifuging. A person skilled in the art will be aware that treatment times might be longer than in the continuous process at the same temperature.
The curing process may also include or consist of passing the non-living material, for example the textile material or plastics material, by a heated surface under pressure such as an iron or a heated roller. During drying processes and curing the non-living material is preferably mechanically fixated in a way to prevent change of the form e.g. shrinkage or dimensional deformation. Further, it is prevented that the N-arylhydrazine derivative is washed out. The curing and/or fixation may be alternatively carried out by a dual-cure process combining heat and UV-light or only by UV-light. Suitable processes are known by a person skilled in the art.
The polymeric binder may advantageously be applied with a fixative agent for improved attachment of the N-arylhydrazine derivative on the non-living material. The fixative agent may comprise free isocyanate groups.
Suitable fixative agents are for example isocyanates or isocyanurates comprising free isocyanate groups. Preferably the isocyanurates are based on alkylene diisocyanates having from 4 to 12 carbon atoms in the alkylene unit, like 1 ,12-dodecane diisocyanate, 2-ethyltetramethylene diisocyanate-1 ,4, 2-methylpentamethylene diisocyanate-1 ,5, tetramethylene diisocyanate-1 ,4, lysinester diisocyanate (LDI), hexamethylene diisocy- anate-1 ,6 (HMDI), cyclohexane-1,3-and/or-1 ,4-diisocyanate, 2,4-and 2,6-hexahydro- toluylene diisocyanate as well as the corresponding isomeric mixtures 4,4'-2,2'- and 2,4'-dicyclohexylmethane diisocyanate as well as the corresponding mixtures, 1- isocyanato-3,3,5-trimethyl-5-isocyanatomethyl cyclohexane (IPDI), 2,4- and/or 2,6- toluylene diisocyanate, 4,4'-, 2,4' and/or 2,2'-diphenylmethane diisocyanate (mono- meric MDI), polyphenylpolymethylene polyisocyanate (polymeric MDI) and/or mixtures comprising at least 2 of the isocyanates mentioned before. More preferably the isocyanurates are based on hexamethylene diisocyanate-1 ,6 (HMDI). More preferably the isocyanurate is a isocyanurate which is hydrophilized with a polyalkylene oxide based on ethylene oxide and/or 1 ,2-propylene oxide, preferably polyethylene oxide.
The isocyanurate used as fixative agent can be prepared by methods known in the art. Preferably 5 to 25 % by weight, more preferably 7 to 20 % by weight, most preferably 10 to 15 % by weight of the isocyanate groups based on the amount of isocyanate used as staring material for the preparation of the isocyanurate are free isocyanate groups.
Most preferably the isocyanurate used as fixative agent is dissolved in a polar aprotic solvent, e.g. THF, DMF or propylene or ethylene carbonate.
The most preferred fixative agent used is an isocyanurate based on HMDI which are hydrophilized with a polyethylene oxide and which is dissolved in propylene carbonate (70 % by weight of HMDI in 30 % by weight of propylene carbonate). The amount of free isocyanate groups is 11 to 12 % by weight, based on the amount of isocyanate used as staring material for the preparation of the isocyanurate.
The insecticide composition preferably comprises the following components, based on the solids content of the composition, if a fixative agent is used: a) 20 to 70 % by weight, preferably 25 to 65 % by weight, more preferably 30 to 65 % by weight of at least one N-arylhydrazine derivative of formula I (component A), and b) 29 to 72 % by weight, preferably 34 to 70 % by weight, more preferably 33 to 66 by weight of at least one polymeric binder (component B) as defined above c) 1 to 8 % by weight, preferably 1 to 5 % by weight, more preferably 2 to 4 % by weight of at least one fixative agent (component C); wherein the sum of the components is 100 % by weight of solids content of the insecticide composition.
Preferred fixative agents are mentioned before.
As described above, the solution or emulsion may further comprise one or more components selected from water, preservatives, detergents, fillers, impact modifiers, anti- fogging agents, blowing agents, clarifiers, nucleating agents, coupling agents, conductivity-enhancing agents (antistats), stabilizers such as anti-oxidants, carbon and oxygen radical scavengers and peroxide decomposing agents and the like, flame retar- dants, mould release agents, agents having UV protecting properties, spreading agents, anti-blocking agents, anti-migrating agents, foam-forming agents, anti-soiling agents, thickeners, further biocides, wetting agents, plasticizers, adhesive or anti- adhesive agents, optical brightening (fluorescent whitening) agents, fragrance, pigments and dyestuffs.
The process may also involve using the kit as described before, accordingly, the impregnation process may be carried out by the end-user in a low-scale process or in a local factory. The present invention therefore relates to a process for impregnating a non-living material as described before, wherein the impregnating composition is provided as a kit for impregnation by the end-user or in a local factory.
In a further embodiment of the present invention the impregnation process which comprises applying an insecticide composition as described before may also take place before the non-living material is further processed, for example fibers are woven or knitted.
In a further embodiment the invention relates to a process for coating a non-living material by applying a composition comprising at least one N-arylhydrazine derivative of formula I and at least one polymeric binder as defined in the present invention to the non-living material. The coating is preferably carried out in a doctor-blade process. The process conditions are known by a person skilled in the art.

Examples of use (example B)
The long-lasting insecticidal treatment was performed with aqueous dispersions ac- cording to examples A1 - A17 on commercially available white polyester netting material (fiber titer 75 denier, 156 mesh, weight 28-32 g/m2) without prior washing. The aqueous treatment baths were prepared by mixing the aqueous dispersions with emulsions of N-ethyl-2,2-dimethylpropionamide-2-(2,6-dichloro-α,α,α-trifluoro-p-tolyl)- hydrazone and N-ethyl-2,2-dichloro-1-methylcyclo-propanecarboxamide-2-(2,6- dichloro-α,α,α-tri-fluoro-p-tolyl)hydrazone, respectively, setting pH with buffer solutions and adding a fixative (if needed). The concentrations of the treatment baths were adjusted according to the liquor uptake possible (LU between 60 and 100 %). The treatment baths were applied by using a padder-stenter equipment on a laboratory scale (Mathis AG, Switzerland). The netting material is fully immersed into the treatment bath and excess liquor is removed by passing it through cylinders which move in counter- direction. By choosing a defined distance between these cylinders (and thus a defined pressure) the liquor uptake can be controlled. The liquor uptake is measured by weighing an impregnated piece of netting and subtracting the weight of the dry, untreated netting and is given as % weight of liquor on weight of netting. The drying/curing step was performed in a laboratory stenter which allows to control the temperature and time of the treatment.
The treated nettings have been washed different times. The washing was carried out by the " Montpellier washing procedure" (as described in the annex WHO PVC1 3/07/2002 " Evaluation of wash resistance of long-lasting insecticidal nets" ): Net samples are washed individually in beakers containing 0.5 L deionised water and 2 g/L soap (pH 10-11) at 30 °C in a water bath shaken for 10 minutes in clean water at 155 movements per minute. The soap used comprises (among further components like etidronic acid and sodium hydroxide or coconut acid, tetra sodium EDTA and limonene) the following ingredients: Sodium tallowate, water, sodium palm kemelate or sodium cocoate, perfume, glycerol, sodium chloride and some dyestuff (C.I. 77891). Samples were bioassayed according to the cone testing procedure described below.
Testing procedure:
The testing follows the basic guidelines of WHO cone testing procedures with a few modifications. Cones (WHO cones (WHOPES 96.1): clear plastic cone structures (11 cm diam.) with a flat flange around the bottom edge and a hole at the apex) are held against treated net pieces (25 x 25 cm) via a hand-made manifold apparatus modeled similarly to CDC (Centers for Disease Control and Prevention) methodology. The manifold device used is made by cutting four holes (9 cm diameter) in a plastic serving tray (30.5 x 41.0 cm, Consolidated Plastics). An unmodified tray of the same dimensions acts as a base. Onto the surface of the base tray two pieces of blotter paper are placed, cut to fit inside the tray. A piece of treated netting is then placed onto the blot- ter paper followed by four WHO cones placed to roughly correspond to the positioning of the holes cut in the manifold (top) tray. This top tray is then placed over the cones so they pass through the holes. The top tray is then securely fastened to the base tray using four large binder clips. The blotter paper helps to ensure a reasonably tight fit of the cones to the netting. Mixed sex mosquitoes, 1-5 days old, are removed from a rearing cage with an aspirator and ca. 5 mosquitoes placed into each cone. A lab timer is started after the introduction of insects into the first cone with each cone supplied with mosquitoes ca. 15 seconds apart, taking one minute to fill all the cones. Each cone is plugged with a rubber stopper immediately after introduction of the insects. Mosquitoes are held in each cone for three minutes where each insect typically rests on the netting surface (if treatment is not strongly repellent). If any mosquito rests on the wall of a cone then the cone can be tapped gently to relocate the insect to the netting. After three minutes, the insects are all removed by aspirator and placed into a plastic holding cup, combining mosquitoes from all four cones, which represent a single replicate. Four replicates of each treatment are recommended. The holding cup con- sists of a clear plastic cup (9 cm tall x 6.5 cm wide) with a plastic screw-on lid. A 1 cm hole in the lid is used to insert the aspirator for insect deposition. One set of mosquitoes from each cone is collected and deposited into the holding container at a time. Between insertions of the aspirator tip into the container lid, an overhead transparency marker is used to plug the hole to prevent insect escape. After all four cones have been emptied of insects into the holding container, the hole is then plugged with a cotton dental wick soaked with 10% sugar water. The end of the wick sticking out of the cup should have the end manually flattened somewhat to ensure that it doesn't fall into the cup and allow mosquito escape. Knockdown (KD) data are generally taken from the pooled mosquitoes at 60 minutes and 24-hours. A 30-minute (or other) reading can be included if deemed necessary. For speed of knockdown, the mosquito can be left in the cone and the time to KD recorded for each individual mosquito. Each KD mosquito is removed as it goes down to prevent recounting that insect if it once again flies. All mosquitoes are then held as described previously for a 24-hour Mortality count.
Results
The nettings treated with an insecticide composition comprising a binder of example A and a N-arylhydrazine derivative of formula Ia-I or Ia-II show an activitiy (knockdown, mortality) after washing of the nettings.
