Abstract
653,573. Carbon papers. FRANCIS, F. G. June 4, 1948, No. 15196. [Class 100 (iv)] A carbon paper for producing a master sheet of the type in which the paper is treated with a spirit soluble transfer material, is rendered clean to handle by coating the layer of transfer material with a varnish layer which is plasticized and includes a wax so that it may be readily broken in use by a type head. The varnish comprises, e.g. a skin forming material such as ethyl cellulose or chlorinated rubber 5 parts, in a solvent such as toluene, xylene or ethyl acetate 90 parts, a wax such as Spermaceti, 4 parts, and the plasticizer, chlorinated paraffin wax, 1 part.
