Definitions
- the present invention relates to a process for the production of a spectacle lens with improved adhesion between an anti-reflection or anti-reflection coating applied to the spectacle lens, which has a single-layer or multilayer structure, and a hydrophobic and / or oleophobic coating.
- the prior art discloses spectacle lenses with an antireflection coating and a hydrophobic coating applied thereto.
- Such coating systems have the problem that the lifetime of a hydrophobic coating is often insufficient, since the adhesion between the antireflection coating and the hydrophobic coating is insufficient.
- the present invention is based on the technical object of providing a method for producing a spectacle lens with improved adhesion between an antireflection or mirror coating applied to the spectacle lens and a hydrophobic and / or oleophobic coating (also known as "TopCoaf”). Coating).
- a process for the production of a spectacle lens with improved adhesion between an antireflection or mirror coating applied to the spectacle lens, which has a monolayer or multilayer structure, and a hydrophobic and / or oleophobic coating the steps:
- a plastic glass for example of polythiourethane, polyepisulfide, PMMA, polycarbonate, polyacrylate or polydiethylene glycol bisallyl carbonate (CR 39 ® ) or any mixtures of two or more of such materials, or a mineral glass can be used.
- the hard layer optionally to be applied in the process according to the invention is not subject to any particular restriction.
- the hard layer may have a single-layer or multi-layer structure.
- Various materials and methods can be used to produce the hardcoat.
- a person skilled in the art is able to select suitable materials for the hard layer and the thickness of the hard layer in a suitable manner.
- the hard layer is applied in the form of a hard lacquer or an inorganic material, in particular quartz-based, by means of plasma-assisted vapor deposition techniques or CVD methods.
- the application of a hardcoat is generally carried out by means of conventional methods, such as a dipping method, a spray method or a spincoat method.
- a silicone resin is applied as a hard layer to the surface of the spectacle lens, for example starting from siloxanes.
- Suitable silicone resins have a composition comprising one or more of the following components:
- organosiloxane compounds with or without functional groups such as glycidoxypropyltrimethoxysilane
- co-reactants for functional groups of functional organosilanes such as organic epoxides, amines, organic acids, organic anhydrides, imines, amides, ketamines, acrylic compounds and isocyanates,
- colloidal silica, sols, and / or metal and non-metal oxide sols which preferably have an average particle diameter of about
- catalysts for silanol condensation such as dibutyltin dilaurate, zinc naphthenate, aluminum acetylacetonate, zirconium octoate, lead 2-ethylhexoate, aluminum alkoxides and aluminum alkoxide organosilicone derivatives and titanium acetylacetonate,
- Catalysts for co-reactants such as epoxy catalysts and free-radical type catalysts
- solvents such as water, alcohols and ketones
- surfactants such as fluorinated surfactants or polydimethylsiloxane-type surfactants
- the layer thickness of the hard layer is fundamentally not subject to any particular restriction. However, it is preferably adjusted to a thickness of ⁇ 10 .mu.m, more preferably 1 to 6 .mu.m, particularly preferably 2 to 3 .mu.m.
- the antireflection coating may have a single-layer or multi-layer structure.
- Such single-layer or multi-layer antireflection coatings are known to a person skilled in the art and a person skilled in the art is able to select suitable materials and layer thicknesses of an antireflection coating or of the individual antireflection layers in a suitable manner.
- An antireflection coating with a one, two, three, four, five or six-layer structure is preferably selected.
- such a layer sequence is usually selected, in which an antireflection layer with a high refractive index adjoins an antireflective layer with a low refractive index.
- antireflection layers with a low refractive index and antireflection layers with a high refractive index alternate alternately.
- further layers for example adhesive layers (for example with a thickness of about 5 nm), which need not have an optical function, but are advantageous for the resistance, adhesion properties, climatic resistance, etc., can be incorporated.
- adhesive layers for example with a thickness of about 5 nm
