Abstract
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.
