Definitions
- the present invention relates to a printable sheet comprising holographic patterns as well as its production method. It also relates to the printable and hot-embossable sheet to form the holographic patterns as well as the use of the layer allowing the production of this sheet.
- Holographic sheets are already known, in particular sheets of paper or plastic which are obtained by applying a holographic foil to a support (the sheet of paper or basic plastic) or by microembossing of the support which has been metallized or else by hot microembossing of a thermoplastic layer extruded on the support.
- a paper with a microembossable layer is for example described in patent US Pat. No. 5,756,183.
- Sheets or films comprising holographic patterns formed in a crosslinkable varnish under ultraviolet radiation or by an electron beam are for example described in the Japanese patent application JP60263140 and in the German patent application DE4132476.
- the main aims of the invention are therefore to solve the problems set out above.
- the Applicant has demonstrated that if a layer is produced which comprises pigments chosen from small mineral pigments, that is to say of a size less than the amplitude of the embossing and from pigments with a specific surface high whatever their size but in small quantity, and their mixtures, micro-embossing and printing in particular by offset become possible.
- amplitude is meant the depth of the grooves created in the layer by embossing.
- this composition has the effect of creating a microporosity of the layer which allows better ink drying and that, moreover, in the case of small pigments, a correct micro-embossing is obtained to obtain a well observable holographic effect and that in the case of larger pigments, this does not harm the embossing because they are in a sufficiently small quantity.
- the Applicant has also found that if the layer is too porous, the embossing is no longer possible because the layer is no longer thermoplastic.
- the invention thus provides a sheet with microembossing with a holographic and printable effect which is characterized by the fact that it comprises a support coated on at least one of its faces, with a pigmented layer comprising:
- thermoplastic binder - a non-water-soluble thermoplastic binder
- type I pigments - medium size pigments less than the amplitude of microembossing
- type H pigments - medium size pigments greater than F amplitude of microembossing and BET specific surface area greater than 10 m 2 / g measured and in a lower quantity or equal to 10% relative to the binder by dry weight
- type I pigments can also have a high specific surface.
- the invention is characterized by the fact that said type I pigments have an average size of less than 1 ⁇ m, preferably between 5 nm and 0.1 ⁇ m.
- the amount of said type I pigments is between 1 and 50% by dry weight relative to the binder.
- the amount of said type II pigments is between 0.5 and 10% by dry weight relative to the binder.
- the pigments are chosen from fumed, precipitated or colloidal silicas, titanium dioxide, precipitated or ground calcium carbonate, kaolins and their mixtures.
- Other pigments chosen from other fillers usually used in stationery and meeting type I or type II criteria may be suitable.
- the best results have been obtained with fumed silicas in the case of type I pigments and with precipitated silicas in the case of type H pigments.
- the layer may also contain other pigments if they are in small quantities, c that is to say pigments of relatively large size and low specific surface, these pigments can be added to improve specific characteristics such as opacity or whiteness for example.
- the haunches are chosen from thermoplastic and crosslinkable haunts; their crosslinking giving them in particular the property of being non-water-soluble.
- these said binders are hats of a non-water-soluble nature or have been made non-water-soluble by crosslinking and are chosen from polyurethanes, styrene-butadiene copolymers, acrylic polymers including styrene-acrylic copolymers, poly ( ethylene-vinyl acetate), rrirrocelhilosic hunts, resins of photocrosslinkable origin, in particular polymers containing one or more unsaturated groups such as the acrylate, methaciylate, allyl, vinyl group, and their mixtures.
- said pigmented layer also comprises thermoplastic coating pigments, in particular polystyrene pigments.
- said pigmented layer is coated with a layer of zinc sulfide or titanium dioxide.
- a layer improves the holographic effect and the scratch resistance of the holographic patterns without modifying the suitability of the sheet for offset printing. It also improves the heat resistance of the sheet and thus makes the sheet printable by laser printing.
- the invention also aims to provide a method of manufacturing the holographic sheet.
- the invention provides a process for rehsation of a printable sheet comprising holographic patterns, said patterns being produced by hot microembossing of a layer deposited on the base support of the sheet. More specifically, it is a process of rehsation of a printable sheet comprising microembossing with holographic effect which comprises the steps following:
- a pigmented layer produced in an aqueous and / or organic medium as defined above is deposited on a base support of the sheet, said binder being a non-water-soluble or crosslinkable thermoplastic binder, - said sheet thus dried is dried,
- microembossing is carried out by microembossing the layer of said preceding sheet on a heated and pressurized embossing device,
- the temperature to which the sheet is heated during embossing is higher than the glass transition temperature of the binder Tg, preferably at most 100 ° C. higher than this glass transition temperature Tg.
- the invention provides a process for rehsation of a printable sheet comprising holographic patterns, said patterns being reahsed by microembossing a layer deposited on the base support of the sheet , said sheet having been preheated. More precisely, it is a process for rehearing a printable sheet comprising microembossing with holographic effect which comprises the following stages:
- a pigmented layer is also deposited on a base support of the sheet, also comprising thermoplastic pigments produced in an aqueous and / or organic medium as defined above, said binder being a non-water-soluble or crosslinkable thermoplastic binder, - optionally dried said sheet thus coated,
- microembossing is carried out by microembossing the layer of said preceding sheet still hot on an unheated embossing device under pressure, - the binder is crosslinked if necessary, during the process.
- the layer is deposited by known means of surface treatment and coating, in particular those commonly used in the papermaking field such as blade coating, air knife coating, CHAMPION bar, curtain, rotogravure, size press or size transfer press.
- a crosslinkable binder in the case of a crosslinkable binder, said binder is crosslinked by ultraviolet radiation or by an electron beam or hot.
- the binder is crosslinked simultaneously with the embossing of the layer and more particularly said binder is crosslinked by an electron beam.
- the photocrosslinking of the binder seems to improve the definition of microembossing and therefore of holographic patterns.
- said binder was crosslinked during the production of the support coated with said layer, in particular during the drying of said coated support.
- This crosslinking makes the binder non-water-soluble.
- Cross-linking of the binder can be partial during drying and continues with cross-linking just before, during or after embossing.
- the hants are generally used in the form of a dispersion in a stabilized aqueous medium (called latex) or else in a non-aqueous solvent medium or in a mixed medium (aqueous and organic solvent); the photocrosslinkable hats (by UV radiation or by an electron beam) are generally used without solvent in the form of mixtures of monomers and ohgomers.
- the hants have a glass transition temperature Tg which is adapted to the temperature at which the embossing will take place, that is to say those whose glass transition temperature Tg is lower than the temperature at which the embossing. It is nevertheless preferable to choose hats whose Tg is as high as possible because the Applicant has observed that the hats of high Tg gave holographic patterns, better resistance to scratching.
- the conventional embossing processes for forming holographic patterns are carried out under pressure, at least 5.10 6 Pa (50 bars) and when hot, the embossing temperature is generally between 50 and 200 ° C.
- pressure at least 5.10 6 Pa (50 bars) and when hot, the embossing temperature is generally between 50 and 200 ° C.
- the choice of the temperature and pressure couple is important to obtain the desired holographic effects of good quality, humans those skilled in the art will be able to determine these data by simple test tests and by reference to the examples cited below.
- any type of support can be suitable, knowing that the support is important in terms of the penetration of the binder and the end use of the product.
- the layer must have a thickness greater than or equal to the amplitude of the embossings, that is to say generally greater than 0.5 ⁇ m. There is no mandatory upper limit, however, the cost and also the use of the sheet must be taken into account.
- the supports can be chosen from uncoated papers, coated papers, natural tracing paper obtained by a thorough refining of cellulosic fibers, possibly colored, transparentized papers impregnated with a transparentizing product, colored papers, security papers in watermarks, seed papers, especially impregnated papers for rehure or cover.
- Security papers are used to make security documents or banknotes, thick seed papers are used in particular to make passport covers.
- These supports can also be plastic sheets or films, in particular sheets or films of polyolefins, in particular polyethylene or polypropylene.
- the supports may have received a treatment promoting the holding of the layer, these treatments being known elsewhere (pre-coating, adhesion primer, Corona treatment).
- the invention also relates to a printable sheet comprising holographic patterns, obtained by the methods as defined above.
- the holographic sheets obtained according to the invention can have many applications. They can be used in the field of creative printable supports to make offset printable supports with a holographic background (geometric patterns, images ....) or with holographic inscriptions in the manner of a watermark always with the aim of creating 3D effects. They can also be used in the field of security documents to provide inexpensive protection (logos, train tickets, etc.), since the holographic motif is not photocopiable and cannot be produced in a simple manner (it is necessary at minimum of a micro-embossing press to counterfeit the product). They can be used to make covers or rehures like passport covers.
- the invention also relates to a coated sheet that can be printed and hot-embossed in holographic patterns, said sheet comprising a layer as defined above.
- the invention also relates to the use of a layer as defined above for laying down a sheet and making it printable and micro-embossable under heat according to holographic patterns.

- the layer is crosslinked by an electron beam during embossing by the plate comprising microembossings in negative of the patterns.
- a sheet is obtained comprising microembossings which form holographic patterns.
- Printing tests are then re-scanned on the micro-embossed side of the papers, using the device called Priifbau Print Test.
- the smear test was repeated with Optima ® ink from the company LoriUeux. This test showed that the paper was printable and that the smearing was satisfactory.
- This composition has a dry extract of 60% and a Brookfield viscosity of 200 mPa.s measured at 100 revolutions / min.
- the quantity deposited is 4 g / m 2 by dry weight.
- the carbonate fraction is 500% relative to the hant (in dry / dry weight).
- the sheet is dried at around 100 ° C., the hant is crosslinked during this drying.
- the layer used corresponds to the usual layer compositions in the field of writing printing.
- the high pigmentation content of large jail (1-2 ⁇ m) compared to the amphrude of the embossings (0.5 ⁇ m) prevents the layer from being embossed. This example therefore shows that a usual writing printing layer is not suitable.
- WIGGINS DRAWING AND FINE PAPER the following layer composition is deposited, using a pilot coater: - Water: 493 g
- the quantity deposited is 7 g / m 2 by dry weight.
- the leaf is dried at around 105 ° C., the hant is crosslinked during this drying.
- holographic patterns are reshuffled on the sheet obtained by embossing the coated side by preheating the sheet at 80 ° C. for 10 seconds and then just after, the sheet remaining hot, microembossing is carried out on a press comprising a plate comprising micro embossing in negative of the patterns, under a pressure of 21.10 6 Pa (210 bar) for 10 seconds, the plate not being heated.
- a sheet is obtained comprising microembossings which form holographic patterns.
