Abstract

A copying process is known in which the original to be copied is coated with a material, which is readily absorbed in the background areas of the original, but to a much lesser degree in the printed areas. This results in a differential absorption between the image and nonimage areas and can be utilized for the production of latent oil images. Thus, in the next step of the process, the oil remaining on the printed areas is transferred by an element, such as a roller, to a copy paper. The oil image on the copy paper is then rendered visible by applying toner particles. Oleic acid is substantially a universal oil for most originals in the above-described process.

Oleic Acid as the Universal Oil

A copying process is known in which the original to be copied is coated with a material, which is readily absorbed in the background areas of the original, but to a much lesser degree in the printed areas. This results in a differential absorption between the image and nonimage areas and can be utilized for the production of latent oil images. Thus, in the next step of the process, the oil remaining on the printed areas is transferred by an element, such as a roller, to a copy paper. The oil image on the copy paper is then rendered visible by applying toner particles. Oleic acid is substantially a universal oil for most originals in the above-described process. Oleic acid can either be dissolved in alcohol and sprayed on the original, or applied undiluted to the original by a roller, or serve as the carrier for an iodine precursor which, when transferred to the copy paper, can be developed by a starch solution.
