    Abstract: 581,449. Adhesive sheets. DU PONT DE NEMOURS & CO., E. I. May 30, 1944, No. 10363. Convention date, May 29, 1943. [Class 140] A sheet, film or tape is coated on one side with a pressure-sensitive adhesive and on the other with a coating comprising an aminophosphatide to minimise adhesion when the material is stacked or rolled. The base material may be paper, cloth, regenerated cellulose, cellulose acetate, methyl or ethyl cellulose, polyvinyl alcohol or acetol, acrylonitrile, polyethylene or polyamides, and may be coated with a moisture-proof composition before applying the aminophosphatide coating. The latter comprises the lecithins, particularly soya-bean lecithin, cephalin or sphingomyelin and may be mixed with resins, pigments, cellulose derivatives such as ethyl cellulose, or starch derivatives or proteins and may be applied to the base as a powder or paste or sprayed in solution in toluene. Examples of adhesives comprise a mixture of the substance known under the Registered Trade Mark "Pliolite" with milled rubber, Piccolyte chlorinated paraffin wax, monobenzyl p-amino-phenol and toluol. Alternatively the adhesive comprises batanaphthol modified rubber prepared as described in Specification 520,985, [Group V], chlorinated diphenyl, chlorinated paraffin wax and toluol. According to the Specification as open to inspection under Sect. 91, when the tape is coated on both sides with an adhesive, interleaves of film coated on one or both sides with the aminophosphatide may be used. This subject-matter does not appear in the Specification as accepted.
