PROBLEM TO BE SOLVED : To provide an in-mold transfer foil which can transfer a fluorescent latent image excellent in heat resistance inhibiting whitening due to heat, and has good followability to extension/contraction even if a shrinkage is high and security properties to a three-dimensional surface with reducing cracks, whitening, etc. ?SOLUTION : The in-mold transfer foil 10 comprises a substrate 11, a mold release layer 13 a fluorescence layer 15 and an adhesive layer 19. The mold release layer 13 is a melamine resin, and the fluorescence layer 15 contains an ionizing radiation curing resin having hard coat properties, a fluorescence emitting rare earth complex and a filler. The absorption wavelength range of the ionizing radiation curing resin is different from the absorption wavelength range of the fluorescence emitting rare earth complex, and the fluorescence layer has (1) an elongation at break at 23°C after ionizing radiation curing of at least 5% and (2) heat resistance inhibiting whitening even when being left for one hour in a 150°C atmosphere in the state of the in-mold transfer foil 10. ?COPYRIGHT : (C)2010, JPO&INPIT ? |
