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 percent by weight of units of at least one hardening monomer selected from the group consisting of (A) isobutylmethacrylate and (B) cycloalkylmethacrylate; and (ii) 5 to 40 percent by weight of units of at least one aliphatic-substance-solubilizing monomer selected from the group consisting of (C) alkylmethacrylates having 6 to 18 carbon atoms in the alkyl residue, where the units of isobutylmethacrylate account for no more than 60 percent by weight and the units of cycloalkylmethacrylates account for no less than 10 percent by weight, based on, in each case, the weight of the copolymerizate.

Aqueous synthetic resin dispersion

A method for priming an absorbent mineral or wood substrate to provide a wet-adhering coating, which comprises applying to said substrate a solution, in an organic solvent which has a normal boiling point between 50.degree. C. and 180.degree. C., of a copolymer of monomers of acrylate and methacrylate esters, of styrene and of vinyl esters, and of dialkylaminoalkyl esters of acrylic acid and of methacrylic acid and their corresponding amides, the maximum glass transition temperature of the copolymer being in the range from 20.degree. C. to 80.degree. C. and the reduced viscosity of the copolymer being in the range from 20 to 60 ml/g.
