Producing transparent microcapsules comprises: (a) preparing a solution； (b) adding 0.02-0.13 wt.% of an emulsifier consisting of an anionic emulsifier and a nonionic emulsifier in a ratio of 1:3-3:1, preferably 1:2-2:1； (c) adjusting the pH-value of the resulting solution to be 2.5-6； (d) optionally adding a defoamer consisting of octanol and decanol in a concentration of 0-0.6 wt.% based on the total weight of the preparation； and (e) adding 9-42 wt.% of at least one hydrophobic material, preferably air-drying alkyd resins and/or oils including linseed oil and desiccated linseed oil. Producing transparent microcapsules comprises: (a) preparing a solution consisting of (i) 0.1-1 wt.% of ammonium- and/or alkali metal chloride, (ii) 0-0.7 wt.% of an aromatic alcohol consisting of dihydroxy- and/or trihydroxy benzene including resorcinol (preferred), pyrogallol and/or phloroglucinol, (iii) 0.1-3.5 wt.% of an amine- or amide-component consisting of amine or amide having at least two amino groups including melamine, diaminohexane or urea (preferred) and/or cyanamide and (iv) 0.3-2 wt.% of a protective colloid, which is soluble in water and an oil-in-water emulsion, preferably consisting of polyvinylpyrrolidone, polyvinyl alcohol, polyvinyl acetate, poly[1-(N-2-methyl-propanesulfonic acid) carbomylethylene], gum arabic and/or poly(ethylene-alt-maleic anhydride) (EMA) and EMA in water, where the total concentration of the non-soluble ingredients is 1.5-7.2 wt.%； (b) adding 0.02-0.13 wt.% of an emulsifier consisting of an anionic emulsifier and a nonionic emulsifier in a ratio of 1:3-3:1, preferably 1:2-2:1； (c) adjusting the pH-value of the resulting solution to be 2.5-6； (d) optionally adding a defoamer consisting of octanol and decanol in a concentration of 0-0.6 wt.% based on the total weight of the preparation； (e) adding 9-42 wt.% of at least one hydrophobic material, preferably air-drying alkyd resins and/or oils including linseed oil and desiccated linseed oil base
