Abstract: A resin powder for solid freeform fabrication includes a particle having a pillar-like form, wherein the ratio of the height of the particle to the diameter or the long side of the bottom of the particle is 0.5 to 2.0, the particle has a 50 percent cumulative volume particle diameter of from 5 to 200 ?m, and the ratio (Mv/Mn) of the volume average particle diameter (Mv) to the number average particle diameter (Mn) of the particle is 2.00 or less.

Abstract: A rubber glove is produced by sequentially performing the step of immersing a glove mold in a coagulating synthetic rubber latex containing synthetic rubber in latex form, thermally expansible microcapsules, and a rubber coagulant to form a coagulant-containing synthetic rubber film on the surface of the glove mold; the step of immersing the glove mold in rubber-incorporating latex to form a gelled rubber layer; the step of heating a rubber laminate composed of the synthetic rubber film and the gelled rubber layer to vulcanize the rubber laminate; and the step of turning the vulcanized rubber laminate inside out, and removing it from the glove mold. This method produces a rubber glove, which is excellent in anti-blocking properties and grip under dry or wet conditions, by a simple procedure and for a low cost.
