Abstract
In an iris for an artificial eye, coloured inert non-plastic granules, fibres, &c., e.g. coloured glass, iron, silver, steel, brass or copper filings or shavings, crushed porcelain, crushed thermoset resins (phenol-formaldehyde, urea-formaldehyde) are disposed in a matrix of acrylic resin, e.g. polymerized methyl methacrylate or other thermoplastic or thermoset resinous material. The iris may be a slice cut from a rod or tube, or may be built up by superimposing rings containing different granules and of varying internal diameters. A rod may be formed by rolling a rod of black thermoplastic or thermoset resin successively in resinous adhesive and in granules of different shades.ALSO:In an iris for an artificial eye, coloured inert non-plastic granules, fibres &c., e.g., coloured glass, iron, silver, steel, brass or copper filings or shavings, crushed porcelain, crushed thermoset resins (phenol-formaldehyde, urea-formaldehyde) are disposed in a matrix of acrylic resin, e.g., polymerized methyl methacrylate, or other thermoplastic or thermoset resinous material. The iris may be mounted on a metal backing. The iris may be a slice cut from a rod or tube, and may be built up by superposing rings containing different granules and of varying internal diameter. A rod may be formed by rolling a rod of black thermoplastic or thermoset resin successively in resinous adhesive and in granules of different shades. Radial lines may be impressed on the iris by die, punch or mould. Reference is made to the painting of markings on paper, celluloid, cellulose acetate, &c. discs, and also to discs of acrylic resin painted with an inert pigment suspended in a solution of resin in solvent.
