Abstract

<PICT:0604111/III/1> In forming a laminated light-polarizer (see Group XX), a plastic or glass support is coated with a uniform film of plastic solution, e.g. polyvinyl butyral in ethyl, propyl or butyl alcohol, by pouring the solution on to the tilted support which is then rotated in a horizontal plane about a vertical axis, excess of the solution being thrown off by centrifugal action and the edges of the support being bevelled as shown at 3 to prevent formation of a rim of solution.
