1. Method of alkyd resin production during the process consisting of a transestrification phase in the temperature of 260 degrees C and polycondensation in the temperature of 250 degrees C, based on composition of polyhydric alcohols, phthalic acid anhydride, and mixture of vegetable oils in the amount above 60% by weight consisting of non-drying rape oil and drying linseed or soybean oil characterised in that, during the process, 0.4-1% by weight of maleate acid anhydride is used, and the amount of low erucic acid rape oil in the mixture of vegetable oils equals to 28-45% by weight, and the amount of linseed or soybean oil equals to 55-72% by weight.
