The invention relates to a powdery pigment preparation containing a
pigment which is dispersed in an acrylate resin and which is
characterized in that the acrylate resin has an average molecular mass Mw
ranging from 40000 to 80000 g/mol and is a copolymer comprised of 50 to
65 mol % ethyl methacrylate, of 30 to 45 mol % butyl methacrylate, and of
0.5 to 5 mol % methacrylic acid. The powdery pigment preparation can be
used for dyeing films, particularly those made of polymethyl
methacrylate. The films do not have any specks nor holes.
