Abstract
The invention relates to removable temporary paint having a release agent including a non-ionic surfactant and having a pH of 3 to 6. The paint includes: 10 wt % to 50 wt % of a natural alkyd resin in an aqueous emulsion, the alkyd resin having a molar mass Mp of 3,000 g/mol to 100,000 g/mol, a polydispersity index lp of 1 to 20, an oil length of 20% to 40%, and an acid index of 10 to 35; at least one inorganic filler and/or pigment; and a sufficient amount of water. The paint can be used as eco-friendly road paint for temporary markings.
