Abstract: The production of aqueous stoving varnishes as described in Specification 665,195 from a mixture comprising (1) a resole of low molecular weight (2) a polyester resin having a hydroxyl value of 150-250 and (3) ammonia or a strong water soluble organic base, e.g. an amine is improved by employing a resole having carboxylic groups i.e. a resin obtained by reacting a hydroxyaryl carboxylic acid with an aldehyde.  In order that the resole may be compatible with the other components the average number of unoccupied positions para and ortho to the phenolic hydroxyl groups should not exceed two; suitable acids are p-hydroxyphenyl acetic acid and glycollic acid.  The polyester resin should have an acid number from 35-70 and a number of C=C linkages which are conjugated or located next to the COOH group. Volatile tertiary amines or aminoalcohols are preferred as the organic base.  In the following examples Ia-Ie carboxylic resoles are described.  Ex. IIa-d describe the plasticising alkyds.  (Ia) o-cresol, salicylic acid and formaldehyde are heated together under reflux for six hours. After removal of the upper layer and of excess reactant by distillation the driedwashed resin is dissolved in soda lye, and mixed with further of formaldehyde and maintained at 33-40 DEG C. for 3 days.  The alkali is neutralised with HCl diluted with butanol and a resin having an acid No. of 130 is obtained (b) technical tricresol is reacted similarly with acetaldehyde and the product with chloracetic acid; the alkaline solution mixed with 120 gs formaldehyde is kept for one week and then acidified with H2SO4 (c) the reactants are diphenylol propane, chloracetic acid and formaldehyde (d) the reaction in (c) is controlled to produce the diphenylol propane glycollic acid semi-ether which is then reacted with formaldehyde (e) the phenol, cresol and cyclohexanone are reacted, the product treated with chloracetic acid and further reacted with formaldehyde.  The plasticising resins are prepared as follows (IIa) 70 gs phthalic anhydride, ricinenic acid and tall oil fatty acids are reacted together at 180-230 DEG C. and the product further reacted with 30 gs phthalic anhydride and then oxidised with hydrogen peroxide (b) part of the phthalic anhydride is replaced by maleic, fumaric or itaconic acid (c) coconut oil fatty acids and pentaerythritol are reacted and the product reacted with fumaric acid (d) the polyester is formed from linseed oil, pentaerythritol, trimethylol-ethane and isophthalic acid.  Stoving varnishes are made up from the above components as follows:-(5) 60 gs of the product IIa, 75 gs product Ia and 20 gs NH3.
