Transparent synthetic resin sheet or film, method for its production and applications thereof.

摘要

A method for producing a sheet or film of a transparent synthetic resin, which comprises discharging onto a continuous substrate moving in one direction a synthetic resin material for the transparent synthetic resin from a discharge die having a linear outlet extending perpendicular to the moving direction of the substrate, casting and curing or solidifying the resin material on the substrate to form a sheet or film of the transparent synthetic resin, wherein the discharge die is continuously or intermittently reciprocated in a direction substantially perpendicular to the moving direction of the substrate.
