Abstract
622,917. Lenticular material. LA RELIEPHOGRAPHIE SOC. POUR L'EXPLOITATION DES PROCEDES DE PHOTOGRAPHIE EN RELIEF M. BONNET. July 26, 1945, No. 19186. Convention date, April 17, 1943. [Class 98 (ii)] Process for producing lenticular material for use in producing parallax panoramagrams comprises first securing a layer of thermoplastic material to a rigid, plane support and then lenticulating the layer of plastic by moulding in a press. The support layer is preferably of glass and may carry on its uncovered surface a photographic emulsion, while the thermoplastic layer may be applied in the form of a sheet, e.g. of cellulose acetate, adhered over its whole surface or at its edges only to the support, or may be applied in the liquid state and allowed to set before lenticulating it. Specification 622,919 is referred to.
