Patent number: 4276392Abstract: A fast curing coating composition that is adapted for use as an automotive topcoat and which upon curing forms a hard, glossy, durable coating exhibiting excellent resistance to solvents and water. The coating composition which may contain greater than about 55 percent by weight of nonvolatile solids and, exclusive of pigments, solvents and other nonreactive components, consists essentially of:(A) a polyepoxide resin having a number average molecular weight (M.sub.n) of between about 140 and about 3,000;(B) a reactive catalyst comprising at least one phosphonic acid derivative;(C) an amino resin crosslinking agent; and(D) optionally, a hydroxy functional additive.The phosphonic acid derivative is included in the composition in an amount sufficient to produce between about 0.8 and about 1.Type: GrantFiled: November 13, 1979Date of Patent: June 30, 1981Assignee: Ford Motor CompanyInventor: Mohinder S. Chattha

Patent number: 4245064Abstract: The invention relates to a solid insoluble carrier which is activated for bonding of nucleophilic groups and to a method of its preparation. The carrier contains active groups --O.CO.O.R, where R is the residue selected from the group comprising nitrophenyl, dinitrophenyl, trichlorophenyl, pentachlorophenyl, N-succinimidyl, N-phthalimidyl, and 8-quinolinyl. Active groups are bonded to polysaccharides, phenol-formaldehyde resins, polyacrylates, or polyacrylamides. The invention further relates to a method for preparation of the polymeric carrier, which consists in treatment of polymers carrying hydroxyl functions and selected from the group comprising polysaccharides, phenol-formaldehyde resins, polyacrylates, and polyacrylamides, with esters of chloroformic acid which contain the above mentioned active groups.Type: GrantFiled: February 12, 1979Date of Patent: January 13, 1981Assignee: Ceskoslovenska akademie vedInventors: Jaroslav Drobnik, Jaroslav Kalal, Jiri Labsky, Vladimir Saudek, Frantisek Svec
