Definitions
- the invention relates to a process for the formation and application of a hydrophilic coating which is highly lubricious in the moist state on a molded part made of plastic or metal, in particular a razor or razor blade unit, in which a solution containing a water-soluble polymer, in particular polyvinylpyrrolidone, is applied to the molded part and cured there becomes.
- the invention further relates to a razor or a razor blade unit with at least one razor blade held on a blade support and a surface adjacent to the razor blade that sweeps over the skin of the user during the shaving process, in particular a cap made of plastic, such as polystyrene or ABS, or of metal that is coated with a the lubricity-increasing device is provided.
- a razor made of plastic in which at least one razor blade is arranged between a razor blade support and a cap.
- the shaver head has an integral solid and water soluble shaving aid.
- the shaving aid is provided in the form of a strip made of the solid but water-soluble material, the strip being arranged in an adjacent position to the razor blade and being attached either to the blade support or to the cap.
- a microencapsulated silicone oil, polyethylene oxide, a nonionic polyacrylamide or a polysaccharide is provided as the water-soluble material.
- a disadvantage of the known razor is that the substance acting as a lubricant detaches from the carrier body and is deposited on the skin of the user in the form of a film. There is thus the risk of causing skin irritation as well as the need to rinse off the lubricating film that dries on already shaved skin, which can be difficult depending on the hardness of the water available.
- the construction of the razor with a plastic strip arranged in a recess is complex and it is not possible to move the strip into the actual vicinity of the cutting edge of the razor blade. In principle, therefore, the known sliding strip is only to be positioned at a location on the shaving apparatus which is unfavorable for the desired usage properties.
- a molded body made of a polymeric substrate and a coating layer applied to this substrate is also known, in which it consists of a polyvinylpyrrolidone-polyurethane interpolymer.
- Various applications, such as contact lenses, catheters, peristaltic pump chambers, condoms and the like, are mentioned for such a shaped body, in which it is desirable to use a material, such as polyurethane, an acrylic acid polyester or a vinyl resin, which has a lower content in the moist state Has a coefficient of friction that is otherwise the case with such materials is possible.

- such requirements do not exist with conventional shavers and it is also not common to use such materials, in particular a polyurethane.
- the razors and razor blade unit are made of polystyrene, the properties of which are not comparable.
- a coating applied by the process according to DE-PS 28 28 617 would not adhere to polystyrene. It is proposed there that a solution of a polyisocyanate is applied to the substrate and, after the solvent has evaporated, a solution of polyvinylpyrrolidone is applied to the substrate treated in this way, after which the solvent is evaporated to give a polyvinylpyrrolidone-polyurethane interpolymer.

- Radically polymerizable vinyl monomers suitable for the purposes of the invention are preferably acrylic acid, methacrylic acid and their derivatives and mixtures of styrene and maleic acid or fumaric acid-containing polyester resins.
- examples are cyclic or open-chain ether groups containing acrylic acid esters or methacrylic acid esters, such as esters of mono- or poly-ethoxylated or propoxylated C1 - C20 alcohols, THF-carbinol acrylate or THF-carbinol methacrylate, hydroxyalkyl esters, such as 2-hydroxyethyl acrylate, 2-hydroxyethyl methacrylate, 2-hydroxypropyl acrylate Hydroxypropyl methacrylate, N, N-dimethylamino-2-hydroxyethyl acrylate, N, N-dimethylaminoethyl metharylate or salts thereof, such as N, N, N-trimethylammonium-2-ethyl methyl acrylate
- polyester resin systems contain maleic acid or fumaric acid and z.
- the hydrophilic vinyl monomer mixtures preferably contain from 0 to 80% by weight, in particular 0.5 to 50% by weight, of hydrophobic monomers, such as methyl methacrylate, butyl acrylate, ethyl acrylate, cyclohexyl acrylate or ethyl hexyl acrylate.
- hydrophobic monomers such as methyl methacrylate, butyl acrylate, ethyl acrylate, cyclohexyl acrylate or ethyl hexyl acrylate.
- Urethane-modified acrylic and methacrylic esters can also be used, which in a known manner, for. B.
- 2-isocyanatoethyl methacrylate with various C1 to C6 alcohols, especially methanol, ethanol or butanol, alkoxy alcohols, such as ethoxylated and / or propoxylated methyl, ethyl, propyl, butyl or hexyl or ethylhexyl alcohol, or can be obtained by reacting hydroxyalkyl acrylates or hydroxyalkyl methacrylates with aromatic or aliphatic mono-, di- or triisocyanates such as hexamethylene diisocyanate, lysine methyl ester diisocyanate, toluene diisocyanate, MDI diphenylmethane diisocyanate or an adduct of trimethylol propane and 3 mol toluene diisocyanate.
- N-vinylpyrrolidone can be used in the hydrophilic vinyl monomer mixture, which is particularly suitable as an additive in the sense of
- Suitable crosslinking components are, for example, butanediol bisacrylate, 1,6-hexanediol bisacrylate, oligoethylene glycol bisacrylates with 1 to 400 ethylene glycol units, acrylates or methacrylates of trimethylol propane, ethoxylated and / or propoxylated trimethylol propane. Also suitable is bis (2 hydroxyethyl) bisphenol A dimethacrylate or an adduct of (meth) acrylic acid and bisphenol A diglycidyl ether or urethane-modified bisacrylates.
