Light-shielding screen and a process for producing the same

摘要

A light-shielding screen comprising a light non-transmitting, photocured resin composition layer and a plurality of hollow portions having their respective upper and lower openings and passing through said composition layer, the hollow portions each having an inner wall extending from the circumference of each upper opening to the circumference of each lower opening substantially in parallel with the axis of said hollow portion. Such light-shielding screen is produced by image-wise exposing a layer of a photocurable resin composition to actinic radiation through an image-bearing transparancy to convert the layer to a modified layer having photocured portions and a plurality of uncured portions and then removing the uncured portions by means of a developer to form hollow portions passing through the modified layer and having their respective upper and lower openings. The present light-shielding screen can effectively shield extraneous light rays without deteriorating the image from an image-indicating device
