Pure-aliphatic compound-soluble powdery bonding agent for paints

A powdery bonding agent for paints which is soluble in pure aliphatic compounds, and which is in the form of powdery polymerizate particles, which consists of, at least on the particle surface, of a copolymerizate formed of:

• (i) 60 to 95% by weight of units of the hardening monomers in amounts of
• (A) 5 to 60% by weight of isobutylmethacrylate and
• (B) at least 10% by weight of cycloalkylmethacrylate or a substituted cycloalkylmethacrylate;
• (ii) 5 to 40% by weight of units of at least one monomer which enhances solubility in aliphatic substances selected from the group consisting of
• (C) alkylmethacrylates having 6 to 18 carbon atoms in the alkyl residue, with monomers A, B and C together constituting at least 90% of the copolymerizate;
• and
• (D) from 0.1 to 10% of monomers containing a polar group.
