The invention relates to a holographic microembossed printable sheet. The inventive sheet is characterised in that it comprises a support which is coated with a pigmented layer on at least one of the two faces thereof. Said pigmented layer comprises: (i) a non-water-soluble thermoplastic binder; and (ii) mineral pigments selected from among: pigments known as type I pigments which have an average size that is smaller than the amplitude of the microembossing; pigments known as type II pigments which have an average siz e that is greater than the amplitude of the microembossing and a measured BET specific surface area that is greater than 10 m2/g in a quantity smaller tha n or equal to 10 % in relation to the binder in dry weight; and mixtures of bo th pigment types. The invention also relates to the method of producing the sheet, the printable sheet which can be hot microembossed in order to form holographic patterns and the use of the layer that enables said sheet to be produced. |
