The present invention relates to thermochromic micro particles capable of stably implementing a high chromogenic property and a decolorization property and having an improved erasing property, thermal resistance, and chemical resistance, and a thermochromic ink composition, a writing apparatus, and a smart window using the same. The thermochromic micro particles comprise a core part including a phase change material, a dye, and a developer, the phase change material including at least one selected from the group consisting of at least one chain hydrocarbon having a carbon number of 8 or more, a hydrated inorganic salt, alcohol having a carbon number of 3 or more, and polyalkyleneglycol; and a shell layer including a polymer resin.

Disclosed is a method for manufacturing a multilayer data medium (1), in which method: a multilayer data medium, including at least one transparent security layer (16), and at least one marking layer (17), sensitive to electromagnetic-marking radiation (5), are selected; the transparent security layer (16) includes at least one semi-transparent printed image including at least one thermochromic dye; at least one marking (30) is made using the electromagnetic-marking radiation, through the printed image; the semi-transparent printed image reveals, in a first state referred to as the inactivated state, at least one semi-transparent visible pattern that makes it possible, after the marking step, to view the marking (30) through the image, the pattern not being visible in a second state, referred to as the activated state. The invention also relates to a multilayer data medium (1).

Drawing control methods, laser irradiating apparatuses, drawing control programs, and recording mediums having recorded therewith are provided that make it possible to efficiently carry out drawing with high quality. The drawing control method controls, by a computer, a drawing device which draws what is to be drawn onto multiple unit regions on a surface of a medium. The computer executes a drawing order determining step which determines a drawing order of a line segment included in the what is to be drawn such that multiple continuing line segments over mutually neighboring multiple unit regions are drawn continuously.
摘要:
The presently disclosed subject matter is directed generally to a polymeric film that comprises at least one laser imageable marking layer. The marking layer comprises a polyolefin, a photochromatic pigment, and an additive. It has been surprisingly discovered that a polyolefin film comprising a marking layer formulated with a photochromatic pigment and an additive offers a substantial advantage over prior art methods of laser imaging polyolefin films.
摘要:
Aspects of the invention include color change compositions having a color former and color developer composition that transitions from a first color state to a second color state upon application of an applied stimulus and an amount of a copolymer sufficient to eliminate background color of the color former and color developer composition during transition from the first color state to the second color state. Methods for preparing and devices employing the color change compositions of the invention are also described.
摘要:
Remote marker systems are disclosed for marking a target using optical markers. Such systems may allow a target to be marked using a remote optical marking device. Also disclosed are photochromic solutions and methods of their preparation.
摘要:
Exemplary embodiments provide compositions and methods for making and using an erasable medium that can contain oligomeric photochromic materials such as spiropyran oligomers, wherein the oligomeric photochromic material can include a plurality of photochromic groups such as spiropyrans covalently connected together by one or more linkers.
