Abstract
Disclosed is a method of duplicating and imaged master comprised of a marking material distributed in an imagewise manner upon a substrate. The method involves contacting the master with a highly viscoelastic inking composition comprising: A. a silicon containing block copolymer having polymeric silicone segments and polymeric segments of a material which is adhesive to the material comprising the image; B. a coloring agent; and C. a solvent in which the copolymer is soluble but which is a non-solvent for the marking material. The inked master is then contacted under pressure with a transfer member to thereby transfer the ink to the transfer member in imagewise configuration.
Claims8
A method of duplicating a master comprised of a thermoplastic organic resin as marking material distributed in an imagewise manner upon a substrate which comprises:
- a. contacting the image bearing substrate with a highly viscoelastic inking composition comprised of:
- 1. a silicon containing block copolymer having siloxane segments and polymeric segments of a material which is adhesive to the marking material, said siloxane segments being characterized by the formula:
- ##EQU2## in which R.sub.1 and R.sub.2 are monovalent organic moieties which may be the same or different and n is a number representing the degree of polymerization;
- 2.
