| 摘要 | A polymer powder (P) selected from a group consisting of (i) a polymer powder (P1) and (ii) a polymer powder (P2) is provided. The (i) polymer powder (P1) includes a (meth)acrylate-based polymer (A1) having a glass transition temperature of 0° C. or less, and the polymer powder has an acetone-soluble component of 5 mass % or more. The acetone-soluble component has a mass average molecular weight of 100,000 or more. The (ii) polymer powder (P2) has an acetone-soluble component of 2 mass % to 35 mass %, the acetone-soluble component has a mass average molecular weight of 100,000 or more, and has a volume average primary particle size (Dv) of 200 nm or more. | ||

| 主权项 | 1. A polymer powder (P1) comprising a (meth)acrylate-based polymer (A1) having a glass transition temperature of 0° C. or less, where the polymer powder has an acetone-soluble component of 5 mass % or more, the acetone-soluble component having a mass average molecular weight of 100,000 or more, wherein the particles of the polymer powder have a size of 10 μm or less in an amount of less than 30 vol % when subjected to disintegration steps (1)-(3): (1) diluting the polymer powder (P1) with ion exchanged water; (2) performing supersonic irradiation at a frequency of 42 kHz and a power of 40 W for 5 minutes; and (3) determining particle size distribution through particle size distribution measurement by laser diffractive/scattering. | ||
