Patent number: 4621133Abstract: A process for the preparation of curable etherified aminoplast resins based on urea/aldehyde polycondensates, and the preparation of surface coating resins.Urea is first reacted with an .alpha.,.alpha.-dialkylaldehyde, as much as 50 mol % of which may be replaced by formaldehyde, in a molar ratio urea/aldehyde of about 1:2, at from 50.degree. to 120.degree. C., in the presence of an acid and in the presence or absence of an alcohol or of other organic solvents, and the 2-oxohexahydropyrimidine derivative obtained in this cyclocondensation is then condensed with formaldehyde in the presence of one or more alcohols and an acid.These aminoplast resins are useful as both acid-curable resins and as resins for baking finishes.Type: GrantFiled: July 5, 1985Date of Patent: November 4, 1986Assignee: BASF AktiengesellschaftInventors: Harro Petersen, Gunther Immel, Wolfram Weiss, Horst Schmidt, Gerd Busse

Patent number: 4390340Abstract: Mineral tanned leather is frequently retanned with synthetic tanning agents to improve the fullness and softness, but leather retanned by the prior art methods is difficult to dye in full shades with anionic dyes. According to the invention, condensation products of C.sub.1-4 aldehydes with certain aromatic sulfonic acids or carboxylic acids containing amino groups are employed for retanning, thereby improving the receptivity of the leather for anionic dyes. These acids have the general formula ##STR1## where X and X' are independently H, --CH.sub.2 --SO.sub.3 H or --CH.sub.2 --OH, A is a benzene radical, Y and Z are independently H, --SO.sub.3 H or --CO.sub.2 H, R is H or C.sub.1-4 -alkyl and n is from 0 to 10, with the proviso that at least one sulfonic acid or carboxyl group is present in the molecule.Type: GrantFiled: June 30, 1981Date of Patent: June 28, 1983Assignee: BASF AktiengesellschaftInventor: Dietrich Lach
