Described herein are coatings which impart oil, grease, and water resistance to various materials, such as paper, paperboard and polymeric materials. Such coatings may be applied as barrier coatings to the substrate materials in order to inhibit and prevent the transmission of oil, grease and water; that is, to prevent oil, water grease from passing into and/or through the substrate material. The coatings include an acrylic-based polymer latex, a styrene-butadiene rubber latex, a styrene-acrylic resin solution, a large particle size wax, and optionally, a small particle size wax. Also disclosed herein is a process of preparing the coatings. Also disclosed are products to which the coatings have been applied in order to impart oil, grease and/or water resistance, and processes for preparing such products.

The present invention relates to a transfer polyester film. More particularly, the present invention relates to a transfer polyester film and a method for manufacturing the same, wherein the transfer polyester film has a coating layer with an excellent releasing property so that at the time of forming a hard coating layer in order to impart a surface gloss to an interior product, the transfer polyester film may be attached to a surface of the hard coating layer so as to allow the surface of the hard coating layer to be smoothly formed in a step of coating and curing a hard coating solution and may be removed after completely curing the hard coating layer.

Coating composition providing gloss and opacity on application, having a pigment volume concentration of from 5% up to the critical pigment volume concentration and characterised in that comprises at least one ground natural calcium carbonate having a volume median diameter of between 0.05 and 0.3 m, and at least one pigment having a refractive index of greater than or equal to 2.5.

A composite system for light diffusion comprises a matrix of a material that is transparent to light; the matrix contains a dispersion of scattering elements having a core that is a nanocluster of inorganic nanoparticles, and a shell comprising silane compounds and dispersing agents; the nanocluster having average dimensions in the range of 20 nm to 300 nm.

Heat ray shielding fine particles contain calcium lanthanum boride fine particles represented by a general formula Ca.sub.xLa.sub.1-xB.sub.m, a shape of each fine particle of the calcium lanthanum boride fine particles satisfies at least one of the following: 1) when scattering intensity of the calcium lanthanum boride fine particles diluted and dispersed in a solvent is measured using small-angle X-ray scattering, value Ve of a slope of a straight line is 3.8Ve1.5, 2) the particle shape is a flat cylindrical shape, or a flat spheroidal (wherein a length of a long axis is d and a length of a short axis is h) shape, with a value of aspect ratio d/h being 1.5d/h20.

Coatings, for example polymer coatings or sol-gel coatings, including at least one layer of micrometric, individualised and mesostructured spherical particles. The particles having been created and loaded with at least one element selected from corrosion-inhibiting functional molecules and corrosion-inhibiting functional nano-objects, by a method having non-dissociable nebulization-heating steps that are continuous in a single reactor. The coatings form an anti-corrosion system, having mechanical strength and/or for coloring. The coatings are applicable, in particular, in the field of protecting light aeronautical alloys against corrosion.

Coating composition providing gloss and opacity on application, having a pigment volume concentration of from 5% up to the critical pigment volume concentration and characterised in that comprises at least one ground natural calcium carbonate having a volume median diameter of between 0.05 and 0.3 m, and at least one pigment having a refractive index of greater than or equal to 2.5.

Coating composition providing gloss and opacity on application, having a pigment volume concentration of from 5% up to the critical pigment volume concentration and characterised in that comprises at least one ground natural calcium carbonate having a volume median diameter of between 0.05 and 0.3 m, and at least one pigment having a refractive index of greater than or equal to 2.5.

Transparent, impact-resistant, anti-icing coatings are disclosed. In some variations, a transparent anti-icing coating comprises: a continuous matrix of a hardened material; asymmetric templates that inhibit wetting of water, wherein the asymmetric templates have a length scale from about 10-300 nanometers; porous voids surrounding the asymmetric templates, wherein the porous voids have a length scale from about 15-500 nanometers; and nanoparticles that inhibit heterogeneous nucleation of water, wherein the nanoparticles have an average size from about 5-50 nanometers. Disclosed coatings have transparencies of 90% or higher light transmission. These coatings utilize lightweight and environmentally benign materials that can be rapidly formed into coatings. A uniform distribution of particles and asymmetric templates throughout the coating allows it to be abraded, yet retain its anti-icing function as well as transparency. Therefore if the surface is damaged during use, freshly exposed surface is identical to that which was removed, for extended lifetime.

Provided are hollow particles each having a shell including at least one layer, wherein the hollow particles have an average particle diameter of 10 to 200 nm and the at least one layer contains a vinyl-based resin.
