Abstract

PURPOSE:To assuredly obtain a foamed body having extremely high magnification, by mixing synthetic resin chips or particles, which contain the second foaming agent having a decomposition temperature lower than that of the first foaming agent, in synthetic resin paint containing the first foaming agent, drying the composition into a gel state, and then expanding the composition with heat. CONSTITUTION:Synthetic resin paint 2 containing the first foaming agent is mixed with synthetic resin chips or pellet-like particles 3 containing the second foaming agent having a decomposition temperature lower than that of the first foaming agent. The composition is then applied as a layer to a substrate 1. After the synthetic resin layer 2 containing the first foaming agent is gelled by drying, the layer is subjected to foaming treatment with heat. Consequently, a foamed body, in which the foamed layer of the first foaming agent-contg. synthetic resin layer 2 is expanded by hollow parts as the traces that the second foaming agent-contg. synthetic resin chips or pellet-like particles 3 mixed in the layer 2 have been expanded under the condition that the tightness of the first synthetic resin layer 2 is held, is produced.
