The present invention relates to a nail polish composition comprising: at least one high gloss film forming agent chosen from a styrene maleic anhydride copolymer; at least one co-film forming agent chosen from an epoxy resin; at least one reactive agent chosen from a combination of a polyalkyleneamine and a polyurethane, at least one polyalkyleneamine, and at least one alkoxysilane comprising at least one solubilizing functional group; at least one solvent chosen from at least one volatile solvent and water; optionally, at least one plasticizer; and optionally, at least one colorant, wherein the composition does not require use of nitrocellulose and can be used to makeup or protect nails.. .
|Semiconductor device, method for producing the semiconductor device, substrate for semiconductor element and method for producing the substrate|
A semiconductor device is provided with a porous structure layer formed by silicone resin between a substrate and a semiconductor element. Alternatively, a porous layer having a density of 0.7 g/cm3 or less, formed by a compound obtained by hydrolyzing and condensing at least one type of alkoxysilane selected from a group consisting of monoalkoxysilane, dialkoxysilane, and trialkoxysilane, and tetraalkoxysilane is provided between the substrate and the semiconductor element.
|Two-step nail polish product|
The present invention relates to a nail polish product, comprising: (1) a base coat composition containing: (i) at least one high gloss film forming agent chosen from a styrene maleic anhydride copolymer; (ii) at least one co-film forming agent chosen from an epoxy resin; (iii) at least one first solvent chosen from at least one volatile solvent and water; (iv) optionally, if water is employed as a first solvent, at least one auxiliary reactive agent chosen from a polyalkyleneamine or a combination of polyalkyleneamine and a polyurethane; (v) optionally, at least one colorant; and (vi) optionally, at least one plasticizer; and (2) a top coat composition containing: (i) at least one second solvent chosen from at least one volatile solvent and water; (ii) at least one main reactive agent chosen from at least one alkoxysilane comprising at least one solubilizing functional group and, if water is employed as a second solvent, at least one polyalkyleneamine or a combination of a polyalkyleneamine and a polyurethane; and (iii) optionally, at least one colorant, wherein the product does not require use of nitrocellulose and can be used to makeup or protect nails.. .
|Graft copolymer, method for the production thereof, and use thereof|
A graft copolymer based on a component a) consisting of silica which has been reacted with an unsaturated silane, and a polymer component b) containing sulphonic acid is proposed. The silica used is preferably a nanosilica and the unsaturated silane is an ethylenically unsaturated alkoxysilane.
|Storage-stable, nco-free laminating adhesive|
The invention relates to a crosslinkable one-component laminating adhesive containing (i) 25 to 80 wt % polyester prepolymers, polyether prepolymers, and/or polyurethane prepolymers that are free of nco groups and comprise at least one crosslinkable alkoxysilane group, as well as additionally nco groups reacted with compounds that contain no hydrolyzable groups, and the prepolymer possesses a molecular weight from 2000 to 30,000 g/mol, (ii) 75 to 20 wt % organic solvent having a boiling point of up to 130° c., (iii) 1 to 20 wt % polymers, oligomers, and/or monomers that contain one or more anhydride groups, (iv) 0 to 15 wt % additives, where the viscosity of the adhesive is between 50 and 20,000 mpas (per din iso 2555), measured at 15 to 45° c.. .
