Organic dispersions which can be cured with little shrinkage and are based on unsaturated polyester, copolymerizable vinyl or vinilydene compounds, thermoplastic polymers which are colloidally soluble and are incompatible with the polyester resin and an ethylene/vinyl acetate copolymer with high vinyl acetate contents show a good stability.

Stable organic dispersions which can be cured with little shrinkage,

Unsaturated polyester moulding compositions hardenable with low shrinkage which are free-flowing comprise a crystalline unsaturated polyester, a copolymerizable vinyl monomer and a graft-polymerized butadiene polymer.

Thixotropic urethane alkyd resins

Highly deformable coatings which are capable of being deep drawn and which are persistent to sterilization can be obtained by using a binder which comprises a mixture of 5 - 30 parts by weight of a benzoguanamine resin and 95 - 70 parts by weight of a polyester which contains o-phthalic acid groups, dihydric and/or trihydric alcohols modified by a polysiloxane of the formula ##STR1## WHEREIN N IS FROM 2 TO 5, R.sub.1 and R.sub.4 are alkyl having 1 to 4 carbon atoms, phenyl, tolyl or benzyl and R.sub.2 and R.sub.3 are alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, phenyl, tolyl or benzyl.
