Abstract: 1,188,376. Making printing masters. XEROX CORP. May 1, 1967 [May 2, 1966], No.20138/67. Heading G2C. A printing master is made by applying to the surface of a substrate a porous coherent or particulate layer of a material whose melting temperature is increased on exposure to actinic radiation, exposing said layer to a pattern of actinic radiation to increase said melting temperature in the irradiated areas and subjecting the material to an environment which converts said layer if particulate to a coherent layer adherent to the substrate and which destroys the porosity of the layer in non-irradiated areas. Said environment is obtained by heating the material to melt and gloss over the non-irradiated areas or by treating the material with a solvent vapour. The porous coherent layer on the surface of the substrate may be prepared by forming a particulate layer and then heating the layer to partially bond the particles to each other and to the surface of the substrate. The surface of the substrate may have an overcoat of thermoplastic resin to facilitate bonding of the porous layer thereto. The material of the porous layer is preferably polyvinyl carbazole or a styrene terpolymer but may also be a photochromic compound, a cinnamic acid ester or a mixture of a non-photo-sensitive polymer and a light-sensitive compound e. g. casein or rubber and an azidostilbene sulphonate or ethyl cellulose or polymethyl methacrylate and a photo-sensitive chalcone or unsaturated ketone. The finished printing master absorbs ink in the porous irradiated areas but not in the glossed non-irradiated areas.

Title: Improvements in or relating to methods of making free-flowing cellular pellets of thermoplastic resins
IPC: C08L27/06
Filed: 1951-08-29
Abstract: A method of making free-flowing cellular pellets of a thermoplastic resin (see Group V), comprises extruding, at temperatures between 60 DEG  and 120 DEG  C., a mobile gel comprising an intimate mixture of a thermoplastic resin having a normally gaseous agent described therein under pressure through a constructed passageway to a zone of lower pressure, cutting the extruding plastic gel into segments before complete expansion occurs and thereafter causing the severed pieces to fall freely through the air while completing the expansion. The mobile gel may be prepared by placing the resin in a ground or powdered form in a pressure-resistant vessel, adding the gaseous agent, and maintaining the mixture under pressure till homogeneous. Suitable thermoplastic resins are polymers and copolymers of styrene, meta-ethylstyrene, meta-chlorostyrene, methylstyrene, para - isopropylstyrene, ortho - chlorostyrene and alpha-methylstyrene; polymethylmethacrylate; and copolymers of vinyl chloride and vinyl acetate or of methylmethacrylate and styrene.  Suitable gaseous agents are methylchloride, methylether, ethyl ether methylethyl ether, ethyl chloride, methyl bromide, dichloro-difluoromethane, normally gaseous olefines such as propylene and butylene and cracked-oil gas fractions containing such gaseous olefines.  The rate of expansion may be retarded by adding barium, calcium, lead or zinc stearate in proportions of from 0.04 to 1 per cent by weight of the resin.  The extrusion pressure may be increased by mechanical forcing of the gel or by introducing to the pressure chamber carbon dioxide, air, nitrogen or the like.  To aid extrusion and cutting of the gela lubricant, e.g. stearic acid, soya oil, corn oil, lard oil or butyl stearate, may be added.  Pigments, fillers or binders, e.g. finely-divided carbon, aluminium powder, titanium dioxide, fuller's earth, powdered calcium silicate or clay may be added.  For rapid vaporization of the gaseous agent in the extruded pellets the air through which they fall may be warmed and instead of air, nitrogen or carbon dioxide may be used.
