Publication number: 20120328989Abstract: A method of preparing a photosensitive printing blank, the method comprising the steps of: a) coating a slip film onto a coversheet and drying the slip film; and depositing at least one layer of photosensitive material on top of the slip film coated coversheet and laminating a substrate layer to the exposed surface of the photosensitive material. The slip film comprises: i) a polymer selected from the group consisting of polystyrene and polyvinylpyrrolidone; ii) optionally, an additive. The slip film at least substantially eliminates the formation of hot spots during an analog plate making process.Type: ApplicationFiled: June 27, 2011Publication date: December 27, 2012Inventors: Kyle P. Baldwin, Miguel A. Barboza, Laurie A. Bryant, Jessica A. Elwell

Patent number: 8329804Abstract: A flame retardant thermoplastic resin composition comprises 100 parts by weight of a rubber-modified aromatic vinyl copolymer resin (A) and about 10 to about 30 parts by weight of a brominated diphenyl ethane mixture (B) including about 55 to about 85% by weight of hexabromodiphenyl ethane. The rubber modified aromatic vinyl copolymer resin (A) according to the present invention is a polymer resin wherein grafted rubbery polymers are dispersed in the form of particles in a matrix of vinyl copolymer. The rubber-modified aromatic vinyl copolymer resin (A) includes grafted rubbery polymers in an amount of about 10 to about 100% by weight and the matrix of vinyl copolymer in an amount of about 0 to about 90% by weight. The brominated diphenyl ethane mixture (B) may have about 1 to about 25% by weight of diphenyl ethane having an odd number of bromine substituents.Type: GrantFiled: November 6, 2009Date of Patent: December 11, 2012Assignee: Cheil Industries Inc.Inventors: In Hwan Oh, Sung Hee Ahn, Sung Duk Hwang, Se Bum Son, Seong Ho Kong, Hye Jin Lee
