摘要:
Pressure-adhesive correction sheets and ribbons which carry a latent adhesive layer which has a surface which is not sticky to the touch but which becomes sticky in areas subjected to applied imaging pressure. The present materials are used for the impactremoval of erroneous images from a copy sheet, which images consist of complementary transfer composition applied by means of a complementary transfer element, including split imaging ribbons carrying both said complementary transfer composition and said latent adhesive correction composition.
摘要:
Pressure-sensitive transfer elements comprising a plastic film foundation and a pressure-sensitive transfer layer characterized by the film foundation having oriented thereto a surface layer having excellent receptivity for the transfer layer. The surface layer comprises synthetic thermoplastic resin and solid particulate filler and is applied to the film foundation to form a combination which is stretched to cause a multiplicity of fine cracks to develop on the surface of the surface layer.
摘要:
Pressure-sensitive reusable transfer elements of the squeeze-out type having a microporous resinous ink-releasing layer firmly bonded to a flexible foundation. The invention is characterized by the use of a bonding layer which is applied to the foundation as an aqueous composition comprising a mixture of two waterdispersible resinous binder materials, one of which is watersoluble and does not insolubilize on drying and the other of which is insoluble in water in that it forms a water-insoluble film on drying.
摘要:
Process for producing novel fabric duplicating ribbons having improved ink-receptivity formed from synthetic thermoplastic filaments, in which the ribbons are rendered more ink-receptive by contact at elevated temperatures with vapor of a compound of titanium, silicon or germanium in the presence of moisture, and are thereafter impregnated with ink.
