Patent number: 4089827Abstract: Curable compositions, suitable for use as surface coatings, comprise(i) 100 parts by weight, calculated on its resin-forming solids content, of an ammonium or amine salt of a carboxyl-containing polyester which contains, on average, at least two mercaptan groups directly attached to aliphatic carbon atoms per molecule and at least one aliphatic group of 8 or more carbon atoms,(ii) from 5 to 100 parts by weight, calculated on its resin-forming solids content, of a water-soluble aminoplast containing, per average molecule, directly attached to an amido nitrogen atom or atoms of urea or of a polyamino-1,3,5-triazine, at least two groups of formula --CH.sub.2 OR, where R denotes a hydrogen atom or a methyl or ethyl group, and(iii) water.Type: GrantFiled: May 5, 1976Date of Patent: May 16, 1978Assignee: Ciba-Geigy CorporationInventors: Derek James Rowland Massy, Kenneth Winterbottom

Patent number: 4085242Abstract: A method of coating an article which comprises blending a reactive polymer and an N,N'-bis(alkoxymethyl)uron to form a homogeneous solution, applying a film of the solution to a surface of the article and baking the article at a temperature sufficient to thermoset the solution. The reactive polymer contains reactive groups such as hydroxyl and carboxyl and is of molecular weight in the range 300 to 5000. The uron ether is employed as a cosolvent for the polymer whereby the solution may be applied as a coating without the need for significant amounts of conventional solvents. Interaction between the polymer and the uron ether promoted by heat in the presence of acid catalyst shifts the role of the uron ether to that of a crosslinking agent for the polymer.Type: GrantFiled: April 11, 1977Date of Patent: April 18, 1978Assignee: Monsanto CompanyInventors: Frank J. Hahn, James O. Santer

Patent number: 4081417Abstract: A process for preparing water-dilutable, heat-curing coating compositions comprises (a) reacting an aromatic polyglycidyl ether with a compound containing an active hydrogen followed by the addition of ethylene oxide to form an adduct containing hydroxyl groups, (b) adding an aminoplast curing agent, and (c) diluting with water to give a stable aqueous composition.The process gives compositions which are useful in preparing coatings for a wide variety of substrates obviating the need for organic solvents with their inherent costs and environmental hazards.Type: GrantFiled: January 31, 1977Date of Patent: March 28, 1978Assignee: Ciba-Geigy CorporationInventors: Kwan Ting Shen, Timothy L. Pickering

Patent number: 4081416Abstract: Pigmented thermosetting aqueous latex coating compositions adapted to deposit coatings which cure on baking to provide superior gloss are provided using an aqueous latex of hydroxyl-functional and mercaptan-terminated aqueous emulsion copolymer particles, the aqueous continuum of the latex having dissolved therein a carboxyl-functional resin salt. An aminoplast resin is dispersed in the aqueous latex to enable the thermosetting cure to take place.Type: GrantFiled: November 9, 1976Date of Patent: March 28, 1978Assignee: DeSoto, Inc.Inventors: Donald J. Berenschot, Dale F. Anders, Fred D. Hawker
