May 26, 1932 I Claims.
The present invention relates to materials such as carbon papers in which the ink is coated upon a carrier sheet. The ings used to this end usually 5 contain fat substances which are intended to embed the. pigments or to dissolve the dyes to be transferred from the carrier to a paper sheet, due tothe pressure exerted by the types of a type-, writer or by a pencil. The present process consists in impregnating the carrier sheet with a fat material before it is coated with ink. For instance a fat material is added to the paper pulp (or like material), intended for carrier making. The penetration of the ink is thus facilitated so I that the transfer material obtained is homogeneous and doesnot tend to roll. In fact, the ink fully penetrates to the whole depth of the sheet, while in the usual papers the ink experiences some difficulties in penetrating to the full depth and the inked surface does not possessthe 29. same hygroscopic features and the same shrinkage in cooling as the surface free from ink. Furthermore, the ink coating is not loosened when struck by the types of a typewriter.
The process of beating or refining the paper pulp is advantageously extended over a longer interval of time, such as would produce a transparent parchment paper, but due to the presence of fat materials properly introduced in the pulp. the paper is on the contrary opaque. a The beating or refining process conveniently carried on enables obtaining a paper free from holes. The inkpenetrates to the full depth of the paper sheet and uniformly "impregnates the same. Hie following important advantages result:
The back or the surface of the sheet not coated with ink is strongly and regularly dyed. The.
absence of holes results in absence ofstains caused by ink passing through the paper sheet. Thus theselling value of the product will be increased without it being necessary to store it for a long time in order to allow for the penetration of the ink.
The coated paper acts'perfectly when cooling groscopic variations.
As fat materials there, can be used substances approaching those which constitute the inks, so that the coating will cause thesolution of the inks in the fat materials added to-the paper.
the: coating and further is not subjected to hy- In France The latter increases the opacity of the paper as well as its weight. When needed lime salts may also be .added.
By-way of an example sodium stearate and oxalic acid are added to a paper pulp while in the hollander, and then the said pulp is used to provide a paper weighing -10 to 25 grams per square meter. The said paper'contains .2 to 5 per cent by weight of stearine. Finally the said paper constituting the carrier is impregnated with ink by coating according to the usual methods.
Having now particularly described and ascertained the nature of my invention and in what manner the same is to be performed, I declare that what I claim is:
1. A process of manufacturing a transfer pa per comprislng introducing a stearine producing body into the paper'pulp, then manufacturing said pulp into paper and then coating said paper with acopying ink.
2. A process for manufacturing a transfer paper comprising adding a soluble stearate to the paper pulp, then adding an acid for reacting with said stearate to said pulp. then manufacturing paper from said pulp and then coating said 'paper with a copying ink.
3. A process for manufacturing transfer paper comprising adding to the paper pulp sodium stearate, then adding oxalic acid'to said pulp, then manufacturing paper from said pulp and then coating said paper with a copying'ink.
4. A transfer paper comprising stearine and having a coating of 9. copying ink.
5. A process for manufacturing transfer paper comprising introducing a stearine producing body into a well beaten paper pulmthen manufacturing said pulp into paper-and then coating said paper witha copying ink.
