摘要:
The invention relates to a process for producing a composite material or a precursor thereof, said process comprising the following steps: (i) printing a support material (A1) with an ink (D) which can be cured by irradiation with light, the support material (A1) (a) being impregnable with a curable resin (B) which after curing is transparent and light-stable, and (b) having a translucency, based on the overall thickness, of 10-95%, preferably 20‑90%, more preferably 30-80% for light in the wavelength range of 200-500 nm; (ii) curing the ink (D) by irradiation with light; (iii) impregnating the thus-treated support material (A1) with a curable resin (B) which after curing is transparent and light-stable, and optionally combining the support material (A1) with at least one further support material (A2); and (iv) curing the curable resin (B) together with or after step (iii); and also to the material obtainable by this process.

The invention relates to a method and device for generating a three dimensional surface structure on a work piece comprising the following steps: feeding a work piece printed with a décor pattern to a processing station; spraying a transparent, radiation-curing varnish through a plurality of nozzle openings onto the surface of the work piece in the form of varnish droplets, wherein the individual varnish droplets have a volume of 0.5 - 300 pl, preferably 3 - 80 pl, particularly preferably 10 - 50 pl, and the number of varnish droplets per surface unit and/or the volume of varnish droplets occurs by means of computer control according to a digital template; and curing of the transparent varnish by means of radiation, preferably by means of UV radiation.

The present invention relates to a heat-sealable label comprising a carrier layer, a print, and a heat- sealable adhesive layer, wherein the heat-sealable adhesive layer is a dried dispersion comprising polymeric particles having a coalescence temperature at or above 500C and at least 10 % (w/w) of the total mass of said polymeric particles are constituted by particles having an average particle diameter of at least about 0.5 µm. This particular adhesive layer results in absence of a tendency of the labels to block when winded up in a roll. Thus, a release layer may be omitted, which allows for a label with more versatile surface properties.

A printed image on the outside surface of a food package fabricated using a thin, flexible substrate may be protected against degradation during retorting of the food package by radiation curing a layer of a liquid composition placed on the outside surface. The liquid composition contains at least one radiation-curable monomer or oligomer containing one or more (meth)acrylate groups per molecule and one or more functional groups per molecule selected from the group consisting of hydroxyl groups and carboxylic acid groups, such as an epoxy (meth)acrylate and/or carboxylic acid-functionalized (meth)acrylate.
