Three-dimensional interaction with autostereoscopic displays

A low temperature curing polyurethane coating system is provided which enables the deposition of adherent corrosion resistant coatings having a desirable balance of hardness and flexibility by using a mixture of a solution copolymer of from 55-85% styrene with the balance of the copolymer consisting essentially of monoethylenically unsaturated hydroxy functional monomer, the copolymer being in solution in inert organic solvent, and an organic polyisocyanate. The polyisocyanate is kept separate from the copolymer solution until the desired liquid mixture is formed and used. Steel substrates coated with this coating system are cured without exceeding 250 DEG F.
