Abstract: This invention relates to novel terpolymers of 3-methylcyclopentene, an omega alkynoic acid and sulfur dioxide. Positive radiation sensitive films prepared from the subject terpolymers adhere well to the substrate, demonstrate resistance to cracking and erosion during development and possess excellent edge definition.

Abstract: This invention relates to novel terpolymers of vinyl acetate, 3-methylcyclopentene and sulfur dioxide. Positive electron beam resist media prepared from the subject terpolymers possesses excellent sensitivity and development latitude.

Positive radiation sensitive films prepared from the subject terpolymers adhere well to the substrate, demonstrate resistance to cracking and erosion during development and possess excellent edge definition.

Abstract: To accelerate printing of resist materials on a CRT color panel, an additive is incorporated into the resist to enhance cross-linking upon exposure to actinic radiation.

Abstract: An amorphous, resistive thin film is deposited on internal surfaces of portions of a cathode ray tube by the pyrolysis of a liquid mixture of colloidal graphite and a heavy metal resinate to produce a film which is a mixture of graphite and the oxide of the metal. The metal resinate is a combination of tin and antimony resinate. The film is deposited on the tube neck in the region of the G3 and G4 electrodes to impede arcing. The amorphous film is also deposited on the tube funnel in the region extending from the snubber contact locations up to the anode voltage terminal. The pyrolysis of the heavy metal resinate and colloidal graphite results in a film having a resistance ranging from 10.sup.3 to 10.sup.8 ohms point to point. The amorphous film which does not require a binder, has good adhesion and scratch resistance characteristics, thereby reducing conductive particle contamination.

Abstract: Highly soluble bismuth salts of organic alkanoic acids are prepared by reacting an organic triaryl bismuth compound with an alkanoic acid in an inert organic solvent, and, after essential completion of the reaction, removing the inert organic solvent to afford the desired bismuth salt.
