Abstract
991,185. Photohectography. COLUMBIA RIBBON & CARBON MANUFACTURING CO. Inc. Feb. 8, 1962, No. 4983/62. Heading G2M. A hectographic sheet for producing a photohectographic master comprises a flexible base having a transferable hectographic layer which is coated with a photosensitive material hardenable upon imagewise exposure, the unexposed areas being tackifiable and removable from the hardened areas together with the corresponding area of the hectographic layer. As shown a base 13 has a hectographic layer 14 with a light sensitive layer 15 thereon, the latter becoming hardened on exposure to light and development. After development, the sheet may be moistened and applied with slight pressure to a master sheet 17. The areas 15a not exposed to light stick to the master and are removed together with portions 14a of the hectographic layer on separation of the master sheet from the hectographic sheet. Specifications 699,052, 975,169 and U.S.A. Specifications 2,312,852, 2,570262, 2,592,368, 2,596,756, 2,634,677, 2,772, 974, and 2,872,863 are referred to.
