8 Claims. (01. 154-40) This invention relates to automobile top mateher in the usual manner, which may be embossed rial and the like, and more particularly to autoifdesired, and then varnished with the following mobile top material of improved appearance and composition, parts being given by weight: greater durability. A portion of the disclosure in Parts 5 this application appeared in application Serial 5 No. 619,210, filed June 25, 1932, Phthahc anhydnde 316 Glycerol 184 Heretofore rubber coated automobile top ma- 500 t erials have been made by coating ordinary rub-- g f i i is 5 g g a ggfiig ber coated fabrics with varnish of the black oil 87 10 10 typ and in some cases with colored varnishes, to f I improve the appearance and to protect the rubber 2 53; ig g L ZZ ZZB m era] 10 film from the deteriorating influences-of sunlight g 1 g 313 and weather.

The material also has the advantage that it .prevents ultra-violet light from reaching the rubber coat, which prolongs the life of the rubberized fabric many times that of a similar fabric which is not so treated. A further advantage of the aluminum surface film is that as the film weathers the surface gradually disintegrates' and disappears, continually exposing a new, bright, clean surface of aluminum, which is essentially the same in appearance as the original unexposed film. This type of finish is particularly advantageous for trucks transporting foodstuffs or other perishable material where excess of heat is to be avoided, and the interior of an automobile or truck with this new material is very appreciably cooler in summer weather than when the usual black colored material is used.
When the automobile top material of the present invention is subsequently varnished or lacquered with a pigmented coating, the intermediate film of aluminum acts as a sealer coat and prevents oils and other softeners of the rubber composition from migrating to the surface film. This function of the aluminum film prevents the dulling and more or less rapid failure of the pig;- mented surface film encountered heretofore in attempting to use a pigmented coating composition other than black over the rubber coated top material. The subsequently applied varnish or lacquer shows a durability comparable to that of a similar composition applied to metal or wood.
As many apparently widely different embodiments of this invention may be made without departing from the spirit and scope thereof, it is to be understood that the invention is not limited to the specific embodiments thereof except as defined in the appended claims.
