Abstract:
1. A decorative material comprising at least a substrate, a low-luster pattern ink layer formed on a part of the substrate, leaving a part of the substrate on which the low-luster pattern ink layer is not formed, and a surface protective layer which is present on and in direct contact with the low-luster pattern ink layer so as to cover a whole surface including both a region where the low-luster pattern ink layer is formed and a region where no low-luster pattern ink layer is formed, wherein the surface protective layer is formed by crosslinking and curing an ionizing radiation-curable resin composition, and provided therein with a first, low-gloss region which is located in a first portion of the surface protective layer just above the low-luster pattern ink layer and in the vicinity of the first portion, and with a second region, located in the surface protective layer in a second portion other than the first portion and the vicinity of the first portion, the first, low-gloss region having a lower gloss than the second region, the low-luster pattern ink layer serving to generate a difference in gloss between the first and second regions, the first, low-gloss region being visually recognized as a concave portion, wherein said first, low-gloss region is a region in which, prior to curing the ionizing radiation-curable resin composition of the surface protective layer, resin components of low-luster pattern ink contained in the low-luster pattern ink layer and uncured radiation-curable resin of the ionizing radiation-curable resin composition are mixed but not completely compatibilized with each other and are kept in a suspended state, which mixture is fixed upon crosslinking and curing the surface protective layer, whereby in the first, low-gloss region the low-luster pattern ink and the resin composition of the surface protective layer have interacted with each other to provide partial elution, dispersion and mixing therebetween, so as to be in a suspended state which is fixed in the first, low-gloss region, the low-luster pattern ink forming the low-luster pattern ink layer containing a non-crosslinked urethane resin and an unsaturated polyester resin as a binder, the non-crosslinked urethane resin having a number average molecular weight in a range of 10,000 to 50,000 and a glass transition temperature in a range of −70° to −40°C.
