Abstract
An improved process for producing a photo-curable composite material using a liquid photo-curable resin, which comprises holding a liquid photo-curable resin with a screen material between two films, at least one of the films having photo-transmitting properties, and passing the films holding the liquid photo-curable resin and the screen material through a gap (e.g. between two rollers). The process of the present invention can produce photo-curable composite materials useful for preparing various stencils for screen printing, textile printing, or the like at a low cost and with less production of defects.
