Abstract:
The invention relates to an amplifying medium for solid-state dye lasers and a solid-state dye laser provided with said amplifying medium. Said amplifying medium comprises an essentially solid active medium, containing at least one sort of particles which can be activated and which can be stimulated to emit laser light of a particular wavelength and optical feedback means which define a resonator for the laser light. The feedback means comprises an essentially solid feedback medium which has a periodic structure. The amplifying medium is characterised in that the feedback medium is a polymeric dispersion film with a crystalline structure which particularly comprises core/shell particles which may be coated.
Abstract:
The invention relates to a coloured coating composition which can be applied to substrates which are to be coated, for example, base paper or cardboard, for the application in the curtain coating method. The substrate, which can be cardboard or base paper, is coated with one or several free-falling liquid curtains. The binding agent is added to the coating fluid. The binding agent is selected from the group containing styrol-butadiene latex binders, styrol-acrylate-latex binders, styrol-butadiene-acrylnitrile latex binders, styrol-maleic acid anhydride binders and styrol-acrylate-maleic acid anhydride binders. The binding agent has a particle size of
Abstract:
The invention relates to a method for the treatment of the surface of textile and non-textile materials, whereby reagent-modified, particulate polymers with a particle size of from 10 nm to 100 mu m are applied to the surface of the materials from an aqueous dispersion and the materials dried.
Abstract:
The invention relates to a treatment method, which promotes the removal of dirt, for the surfaces of textiles and non-textiles. According to said method, cationically modified, hydrophilic nanoparticles, based on cross-linked polymers, are applied from an aqueous dispersion to the surface of the materials. Said cross-linked polymers consist of (a) between 60 and 99.99 wt. % of one or more ethylenically unsaturated monomers containing carboxyl groups, or the salts thereof, (b) between 0 and 40 wt. % of one or more water-insoluble, monoethylenically unsaturated monomers, (c) between 0.01 and 30 wt. % of one or more ethylenically polyunsaturated monomers, (d) between 0 and 25 wt. % of one or more monomers containing sulphonic acid and/or phosphonic acid, or the salts thereof, (e) between 0 and 30 wt. % of one or more water-soluble, non-ionic monomers. The dispersion of the hydrophilic nanoparticles can be stabilised with anionic, non-anionic and/or betainic emulsifiers and/or protective colloids. The hydrophilic nanoparticles have a particle size of between 10 and 2 mu m and are modified cationically by covering their surface with one or more cationic polymers, one or more polyvalent metallic ions and/or one or more cationic surfactants.
Abstract:
The invention relates to aqueous paper coating slips containing organic polymers as binding agents and inorganic pigments. The invention is characterised in that the binding agents are at least partially in the form of pigment-polymer hybrids and are chemically or physically bound to the inorganic pigments.
Abstract:
An aqueous paper coating slip comprising organic polymers as binders and inorganic pigments, wherein the binders are present at least partly in the form of a pigment-polymer hybrid in which the binder is chemically or physically bound to the inorganic pigments.
Abstract:
The invention relates to a method for producing filled papers and filled paper products by adding an aqueous suspension of at least one finely particulate polymer-pigment hybrid to a paper-making stock and dewatering the paper-making stock while forming sheets. The polymer-pigment hybrid is obtained by grinding an aqueous suspension of at least inorganic pigment in the presence of at least one binder and optionally by drying the aqueous suspension so obtained and redispersing the dried polymer-pigment hybrid in water. The invention also relates to the polymer-pigment hybrids so obtained as fillers for producing filled paper or filled paper products.
