    摘要： A pellicle film comprised of a resin prepared by reducing a polyvinyl acetal of the formula: ##STR1## wherein R is a C1-3 alkyl group and the vinyl acetate content "y/(x+y+z)" is not larger than 0.1 and the degree of acetalization "z/(x+y+z)" is at least 0.6. This pellicle film exhibits a reduced UV absorption in the vicinity of 365 nm and is durable against irradiation with UV rays, especially i-line of a mercury arc light.
