Abstract
Pigment-oil suspension ink images are fixed by transferring the images to a transfer paper containing an oil-absorbent masking agent and a physically discontinuous overcoating of a thermoplastic fusing material, and then heating the composite to fuse and fix the images.
Claims9
A method for fixing an image, comprised of marking particles suspended in an oil carrier, which comprises:
- a. applying said image to a transfer paper comprised of a paper substrate which contains an oil-absorbent masking material, and which bears a physically-discontinuous overcoating of a thermoplastic fusing material;
- b. heating said fusing material beyond its melting point such that the fusing material flows and forms an essentially continuous overcoat on the paper;
- and
- c. allowing said fusing material to cool to fix the image.
