This invention relates to the manufacture of a coated paper particularl adapted for artists usein tracing the out in es of drawings and the like, which is commonly used by placing-it between thedrawing to be .copiedand a sheet to receive the impression, with the coated side of the paper against the impression receiving sheet, and it is there fore of importance that the coating be such that it will be readily impressed upon the receiving sheet, leaving clear, clean lines without smuttin'g, and that the composition of the coating be such that the impressed lines may be readily erased from the receiving sheet if desired. Further, it is necessary that the composition of material forming the coating be such that the lines impressed may be worked over with ink, water colors, paints or other material used by artists, and such that the coating will not readily rub off in handling.
The object of the invention is'to' provide a coated paper or a coating material for paper having the above and other desirable characteristics, the invention consisting in the matters hereinaftef' set' forth and more particulaial y pointedout in the appended claims.
he coating material'co'nsists of soft soap made in the usual manner by boilin fatty substances with a lye usually derive from wood ashes, or potash, thus idecomposin the fats into acids and then incorporating therewith a suflicient quantity of fine carbon material, such as a soot deposit' fromthe smoke of burning soft coal, to make a thin black paste. Thisv paste is then spread, in any suitable manner, upon sheets, preferably of thin paper and allowed'to dry. It may then be burnished or given a smooth glossy finish by passing any suitable device having a smooth hard surface, over the surface of the coating.

Apaper particularly adaptable for artists use in tracmg 1s thus provlded, the coating lying wholly uponthe surface of the paper.
but adhering firmly thereto, and having sufiicient hardness so that it will not rub off too freely and smut the fingers, paper, or other things with which it comes in contact, while at the 'same time leaving a clear black line impression-in tracing without requirement of undue pressure of the tracing instrument thereon. The coating being free of oily or greasy substances, does not penetrate the paper with which it is coated and will not soil the impression-sheet or interfere with the workin .over of the lines impressed thereon, wit ink, water colors, or any other of the materials usedby pictures. Further, the lr'npress'ed lines may be as readily and ,cleanly erased as lead pencil marks, due to non penetration of the sub-.
stance forming the coating and the absence of free oil or grease, and this coated paper does not deteriorate with.age.
The composition of material permits of giving the coating a glossy finish by simply artists in making smoothing the surface by frictional contact of a hard smooth surface therewith, thus making the material less liable to rub ofi and giving an attractive appearance' The preparing and applying'of the coating machinery as desired, and a very e cient and durable paper which is cheap to manufac ture is secured.
