摘要

This invention relates to a sunshade type device that has the distinctive feature of allowing sunlight and heat to pass but prevents the passage of ultraviolet rays. The device, of conventional sunshade configuration, has a film (1) consisting of three layers. Each layer (1-a) (1-b) and (1-c) consists of copolymers. To these layers are added additives to absorb and stabilize the ultraviolet rays. The invention allows the user, at the beach for example, to sunbathe and feel its warmth, while being protected from the damaging effects of ultraviolet rays. (-% ** So eSv I-a1-1c Fig. 3
