Abstract:
1. A method of forming a film comprising of at least one layer of at least one resin, which method comprises directing droplets of a liquid composition comprising: a) the said at least one resin; and b) at least one curable diluent onto an array of locations on a substrate, the liquid composition being such that the droplets, on impact with the substrate, spread out to form droplet relics on the substrate that have a diameter at least 1.4 times the diameter of the droplets in flight, such that adjacent droplets merge to form a continuous layer of substantially uniform thickness on the substrate; and curing the curable materials in the continuous layer to solidify the layer, wherein said composition contains substantially no non-curable diluent and wherein the layer has a thickness of less than 10 μm and wherein the said resin comprises liquid cristals and the film includes a liquid crystal alignment layer under the said liquid crystal layer.
