<p><P>PROBLEM TO BE SOLVED: To provide a hologram transfer foil, which has favorable heat resistance and following-up properties to expansion and contraction, few cracking and whitening and can transfer to a three-dimensional surface. <P>SOLUTION: This transfer foil consists of a base material 11, a releasing layer 13, a protective layer 14, a hologram layer 15, a reflecting layer 17 and a bonding layer 19 under the condition that the releasing layer 13 is made of a melamine base resin, the protective layer 14 is set to include a hardened matter of an ionizing radiation curable resin M containing a specified urethane (meth)acrylate oligomer and a (meth)acrylate oligomer and a lubricant, and, at the same time, the hologram layer 15 is set to include a hardened matter of the ionizing radiation curable resin M containing the specified urethane (meth)acrylate oligomer, a (meth)acrylate oligomer and a reactive silicon under the condition that the extensions at break after being cured by ionizing radiation of the protective layer and of the hologram layer are at least 5% and, the hologram transfer foil has so high heat resistance as not to develop whitening even at an elavated temperature. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
