Abstract: Seed holes (h) are formed by discharging a pressure medium (G) in a resin body (R) injected in a cavity (4) of a die (MS1). By expanding the cavity (4), supplying the pressure medium (G) to the seed holes (h), a size of the resin body (R) is increased, making the seed holes grow, to have a molded resin plate (Vr1) made of the resin body increased in the size and formed with the seed holes grown to internal voids (Vd).

Abstract: Acrylic urethane paint composition for forming a hard coat layer of a paint-substitution film fixed on a molded plastic article. The acrylic urethane paint composition comprises a two-part acrylic urethane resin component including acrylic polyol dissolved in an aprotic organic solvent, and a prepolymer having not less than di-functional isocyanate group. Additionally, hydrophobic silica particulate is dispersed in the two part acrylic urethane resin component and has a diameter ranging from 5 to 300 nm. Hydroxyl groups existing at surface of said silica particulate being substituted with hydrophobic groups at a substitution percentage of not less than 15%.
