Abstract: A method of curtain coating a substrate with at least one layer of liquid coating material comprising: moving the substrate along a path through a coating zone; providing one or more liquid coating materials in the form of a free-falling curtain which extends transversely to said path and impinges on said moving substrate; laterally guiding said free-falling curtain by edge guide elements; providing an edge guide fluid in contact with the free-falling curtain and the edge guide elements, wherein the edge guide fluid is an elastic liquid having a recoverable shear of at least 2 at a shear rate of 10,000 s?1, as measured by means of a cone-plate rheometer, and comprising an aqueous solution of an organic polymer.

Abstract: A method and a device for determining shadows in a computer-generated image are provided, wherein the determination whether a pixel x is in shadow is based on a shadow test function ƒ(d(x), z(P)), d(x) representing the depth of the pixel x with respect to the light source and z(p) being a shadow map z for the computer-generated image. According to the invention, the shadow test function ƒ satisfies f ? ( d ? ( x ) , z ? ( p ) ) = ? i = 1 N ? a i ? ( d ? ( x ) ) ? B i ? ( z ? ( p ) ) wherein ai are weighting coefficients depending on d, Bi are basis functions in terms of z and N is a natural number.

Abstract: Coating compositions comprising a pigment and starch dispersion of discrete crosslinked starch particles in an aqueous liquid. The dispersion may be used as coating color for paper. A preferred process of preparing the dispersion of starch particles comprises (a) obtaining a mixture of starch and an aqueous liquid; (b) processing the mixture using shear forces in the presence of a crosslinker in an extruder; and (c) injecting a hydroxylic liquid into the extruder and dispersing the mixture inside the extruder or outside the extruder or both inside and outside the extruder to obtain the dispersion.
