摘要： The invention relates to a coating composition having an amine value of 6-90 mg KOH comprising: i) from 40-97 wt. % of reactive compound (M) containing at least one free radically polymerizable double bond, ii) from 2.5-20 wt. % of radical photoinitiator (R), iii) amine compound (D) containing at least one amino group and iv) non-photobleaching colored dye (C) which is able to react with freeradicals under bleaching of its color, wherein the wt. % is relative to the total weight of the composition, (M) is different from (R); (D) is different from (R); and (C) is different from (R) and (M); and the radical photoinitiator (R) contains species that are able to interact with amino groups in such a way that the generation of free radicals is activated when exposed to electromagnetic radiation.

摘要： Tunable thermochromic materials comprise a metal salt with a varying proportion of two different anions and an organic ligand. Partial substitution via doping during the initial synthesis with a macro-structurally similar (generating an isostructural material) yet chemically different anion creates a material with altered thermochromic properties. For example, in bromide-doped bis(N,N′-diethylethylenediamine)nickel(II)) tetrafluoroborate; both the tetrafluoroborate (BF4-) and bromide (Br—) derivatives are isostructural. Substitution of BF4- for Br— causes a decrease in the materials' thermochromic transition temperature by approximately 10° C.

摘要： An information medium according to an embodiment of the present disclosure includes two or more data layers provided on a support base. The two or more data layers have two or more pieces of visible information recorded on the two or more data layers. The two or more pieces of visible information are obtained by decomposing two-dimensional visible information and thereby allowing synthesis of the two or more pieces of visible information to result in the two-dimensional visible information.

摘要： Formation of a multi-colored image in thermochromic material involves controlling operation of first, second, and third heat sources. The first heat source heats pixels of the thermochromic material to activate the pixels. The second and third heat sources are selectively controlled to heat different sets of pixels using neither, one, or both of the second and third heat sources.

摘要： An approach for forming a multi-colored image on a substrate that includes a thermochromic material capable of producing at least two different colors is disclosed. Individually selected pixels of the thermochromic material that correspond to the image are heated to predetermined temperatures. Each predetermined temperature corresponds to a predetermined color shift of the thermochromic material. While the individually selected pixels are being heated, an area that includes the individually selected pixels is flooded with an amount of UV radiation sufficient to at least partially polymerize the thermochromic material. A color of each individually selected pixel is determined by a predetermined temperature to which the pixel is heated and the amount of UV radiation to which the pixel is exposed.

摘要： Provided is a multilayer lamination film for laser printing that does not require a special ink that discolors by laser light irradiation, and that makes it possible to obtain a printed line having high visibility by irradiation of laser light having a power sufficiently low to avoid damaging a base film. The multilayer lamination film for laser printing includes at least a base material layer, a printing layer, and a sealant layer. The printing layer is a layer made of an ink composition enabling printing by means of laser light. The ink composition is made of white ink containing at least a titanium oxide and a binder resin, the binder resin containing a crystalline component.
