Powder pigment compositions for dyeing films |
摘要 |
<p>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 molar 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 dying films, particularly those made of polymethyl methacrylate. The films do not have any specks nor holes.</p> |
