摘要： Describes a composition for producing durable coatings and a process for preparing a single-layer broad band antireflective coating on solid substrates, such as glass, ceramics, metals, and organic polymeric materials. The coating composition comprises, in combination, acid catalyzed hydrolysis and condensation products of water-silane monomer mixture and a film forming amount of a polymer having functional groups selected from amino, hydroxy and carboxy, hydroxy and amino, amino and carboxy, and amino, hydroxy and carboxy. The described process comprises applying the aforesaid coating composition (or an acid catalyzed sol-gel coating composition) substantially free of preformed oxide sol and water soluble metal salt to the surface of a solid substrate, curing the applied coating, and treating the cured coating with an aqueous electrolyte solution for a time sufficient to produce a coating having graded porosity which is antireflective over a broad band of the visible spectrum.

摘要： A coating composition which exhibits excellent sag resistance without the necessity for externally added rheology control agent is prepared from a curing agent and an ungelled hydroxyl functional graft copolymer. The graft copolymer is prepared by the vinyl addition polymerization, in an inert organic solvent, of a vinyl monomer component containing at least a portion of a carboxyl functional vinyl monomer in the presence of a glycidyl ester containing acrylic polymer. The grafting occurs by the condensation reaction between the carboxyl groups of the vinyl monomer component and the epoxy groups of the glycidyl ester containing acrylic polymer.

摘要： A stable aqueous dispersion containing cellulose ester, the dispersion being polymeric microparticles comprised of cellulose ester and a polymer formed from at least two different vinyl monomers of which at least one vinyl monomer is polyethylenically unsaturated. The dispersion of microparticles is formed by a high stress technique prior to polymerization of the vinyl monomers in the presence of the cellulose ester. Typically the dispersion also contains surfactant. A method of making the stable, cellulose ester-containing aqueous dispersion by (a) mixing together a cellulose ester, at least two vinyl monomers of which at least one vinyl monomer is polyethylenically unsaturated, surfactant, and water to form an emulsion; (b) particulating the emulsified mixture of (a) into microparticles by a high stress technique; and (c) copolymerizing the vinyl monomers in the cellulose ester-containing particulated emulsion of (b) to form a crosslinked polymer within the microparticles of the dispersion. Also aqueous coating compositions formed from the stable cellulose ester containing aqueous dispersion; crosslinking material; and, optionally, additional film forming resins. The aqueous coating compositions can also contain pigments. The coating compositions are very advantageous, particularly in automotive base coats containing metallic pigments and exhibit good humidity resistance, appearance, adhesion and chip resistance when used in an automotive "low bake repair" process.
