Abstract

Resinous compositions, especially coating-compositions, are obtained by combining dimethylol urea with a non-hydroxylated fatty oil modified alkyd resin which has been prepared with polyhydric alcohol in excess of that theoretically required for the alkyd resinforming reaction, e.g. between 5 and 30 per cent. The dimethylol urea may be suspended in an organic solvent for the alkyd resin and added thereto, or the alkyd resin may be dissolved in a solvent and dimethylol urea added. Examples are given of the production of alkyd resins from various oils with glycerine and phthalic anhydride, the resins being combined with dimethylol urea dissolved or dispersed in monoethyl ether of ethylene glycol or butyl alcohol and the mixture heated, with agitation, until substantially all of the dimethylol urea is dissolved. The oils referred to are perilla, soya bean, rapeseed, menhaden, coconut, chinawood and oiticica; linseed or cottonseed oils may also be employed. Other liquids for dissolving or dispersing the dimethylol urea include the monomethyl ether of ethylene glycol and ethyl, amyl and isobutyl alcohols. The prepared compositions may be used directly as coating-compositions or may be combined with pigments and fillers. The resin solution may be combined with cellulose derivative, e.g. cellulose nitrate, compositions to produce lacquers which may contain softeners, plasticizers, other natural or synthetic resins, pigments or fillers. The coatings may be air-dried but are preferably baked, e.g. at a temperature of 200 DEG F. for 1/2 hour or for a range between 1 hour at 140 DEG F. and 15 minutes at 250 DEG F. Specification 344,401 is referred to.
