RESIN COMPOSITION FOR FORMING TRANSPARENT HEAT INSULATION LAYER, AND TRANSPARENT HEAT INSULATION LAYER AND TRANSPARENT HEAT INSULATION FILM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To simply manufacture and provide a transparent heat insulation film which has low thermal conductivity, is excellent in heat insulation properties, and has higher visibility.SOLUTION: There are provided a resin composition for forming transparent heat insulation layer which contains silica fine particles (A) surface-modified with a compound having a phenyl group, polysilane (B) having a unit represented by general formula (1), and an ionizing radiation curable resin composition (C) and an oil-soluble azo polymerization initiator (D), where as for a content ratio with respect to the total solid content in the composition, the polysilane (B) is 0.1-10 mass%, the ionizing radiation curable resin composition (C) is 4-50 mass%, and the oil-soluble azo polymerization initiator (D) is 10-30 mass%; and a transparent heat insulation film 10 has a transparent heat insulation layer 2 formed thereon by applying and curing of the resin composition for forming transparent heat insulation layer onto a transparent base material 1.SELECTED DRAWING: Figure 1
