【発明の詳細な説明】
［産業上の利用分野］
本発明は非接触高速印字識別方法として注目され乍ら視

た方法であり、第１項は目視視認性を向上する方法、第
２項は印字記録を情報として読み取り出来る方法である
。[Detailed Description of the Invention] [Industrial Application Field] Although the present invention has attracted attention as a non-contact high-speed printing identification method, it has been difficult to select a workpiece that is compatible with visibility, and the laser marking method that was expected from the beginning has not been used. These are methods considered from the perspective of processing materials, and the first item is a method to improve visual visibility, and the second item is a method that allows printed records to be read as information.
［従来の技術］
レーザーマーキング法は当初期待された記録印字方法で
あったが被加工物の選択に制限を受けて印刷記録と液体
噴射記録の方法が一般化して特別な応用範囲にのみレー
ザーマーキング法が使用されているが、高速多量に非接
触印字が出来て印字後の摩耗、剥離、改ざん、等に有利
な記録は期待された実用化には達していない、 之等の
諸原因を追及して従来の記録方法と異なった方法にも思
考錯誤が当然束められる。[Prior art] The laser marking method was initially a promising recording and printing method, but due to restrictions on the selection of workpieces, printing and liquid jet recording methods became commonplace, and laser marking was limited to special applications. However, the expected practical use of recording that enables high-speed, large-volume non-contact printing and is advantageous against wear, peeling, tampering, etc. after printing has not been achieved. Naturally, errors in thought and error are bound to occur in methods that differ from conventional recording methods.
［発明が解決しようとする課題］
本発明は狭義の問題を解決するもので無く一般に最終検
査工程で品質保証と品質管理の記録を生産者側に止どま
らず公表する手段に最も適当な印字刻印記録の汎用化に
有効な課題を解決する方法である。[Problem to be solved by the invention] The present invention does not solve the problem in a narrow sense, but is generally the most suitable means for disclosing quality assurance and quality control records in the final inspection process, not only to the producer side. This is a method to solve problems that is effective for the generalization of printed and engraved records.
本課題を解決する為に従来市場に提供されている原料素

が成されなければ成らないと考える。 しかし乍ら上記
の表示記録方法に期待出来る使用範囲は現に身近な印刷
と塗料にも巾広い産品を対象に利用出来る課題の解決に
当たる。In order to solve this problem, the problem can be solved by changing the blending ratio of raw materials conventionally provided on the market and specifying the coloring material, but in terms of the application range to which this application can be applied, the main component is a metal compound. Since it is a use, I believe that sufficient consideration must be given to its suitability. However, the scope of use that can be expected from the above-mentioned display and recording method is to solve problems that can be applied to a wide range of products, including printing and paint, which are currently familiar to us.
［課題を解決するための手段］

た作用と成る、またこの時間経過に注目した材料の特性
を選択利用する事が課題を解決する方法と考える。[Means for solving the problem] Irradiation with a beam of light in the infrared region, which is generally called the laser marking method, damages the molecules of the irradiated object in a very short period of time (10 milliseconds).
This is a method of irradiating a light beam of 0.01-0.2 J per 1 mm in 100 nanoseconds). The surface of the object to be irradiated is irradiated with energy and heat rays that cause photochemical changes, and the molecules are converted to light energy. Imprinting is done using a method that changes quality, including partial combustion, due to instantaneous heating, but chemical changes in pigments, resins, auxiliaries, etc. and thermal effects that occur during this short period of time affect the engraving effect as well. We believe that the method to solve the problem is to selectively utilize the characteristics of the material that focuses on the passage of time.
非加工物の材料からの考察として、先ず本来塗料と印刷

合状態と分子構造が光と熱線被曝前後の状態、更に熱に
対しての性質（熱硬化性／熱軟化性）等の物性に留意し
て加工後更に経時経過での退色と産品の品質を保持出来
る手段を思考しなければ成らない課題と認識する。As a consideration from the perspective of materials for non-processed products, the original goal of improving coloring materials such as paints and printing inks was to create materials that do not easily fade in the light of a wide range of light, including the visible range, from the daily environment, that is, sunlight. It is no exaggeration to say that this history is a history of improvements aimed at developing materials that are less susceptible to surface deterioration.This is because methodologies cannot be advanced unless we address requirements that contradict the problems that this subject is trying to solve. This is a problem that cannot be addressed in the classification of materials that are valid for the mark method. Therefore, the blending ratio of the resin and auxiliary agent, which are products of polymer chemistry that show remarkable changes in a specific light region, especially the polymerization state and molecular structure before and after exposure to light and heat rays, as well as the properties against heat. We recognize that this is an issue that must be addressed by paying attention to physical properties such as (thermosetting/thermosoftening) and considering ways to prevent discoloration over time after processing and to maintain the quality of the product.
［作用］
作用としての期待は 光沢、剥離、硬度、摩耗、耐水、
等に有効な樹脂材料に包まれた色彩材料を変色させる作
用は先ず顔料などの成分が光励起に因る変成と加熱分解
する工程から解明しなければ成らない、 金属化合物で
ある顔料（彩色材料）は樹脂の殻の中に閉じ込められて
居る為照射波長を透過する材料と遮断する材料の配分の
検討が先行する。[Action] Expected effects are gloss, peeling, hardness, abrasion, water resistance,
The effect of discoloring a coloring material wrapped in a resin material, which is effective for coloring, etc., must first be understood from the process of denaturation and thermal decomposition of components such as pigments due to photoexcitation.Pigments (coloring materials), which are metallic compounds Since it is confined within a resin shell, consideration must first be given to the distribution of materials that transmit the irradiation wavelength and materials that block it.
次ぎに光照射に因る彩色材料分子の光励起と加熱変化で
変色した分子を抱合する熱軟化性の樹脂材料の配合が確
定出来れば本発明の作用は実証出来る。 彩色材料の成
分と金属固有の性質から各々の融点と沸点が異なる事情
で樹脂の配合比率は当然異なる面倒は避けられないが、
之は個々の製品加工工程にも付随する製造技術の課題と
相違は無いと理解する。Next, the effect of the present invention can be verified if the formulation of a thermosoftening resin material that binds molecules that change color due to optical excitation of colored material molecules caused by light irradiation and heat change can be determined. Due to the different melting points and boiling points of each coloring material and the unique properties of the metal, it is inevitable that the blending ratio of the resin will vary.
We understand that this is no different from the manufacturing technology issues associated with individual product processing processes.
［実施例］
現在の段階では彩色材料（顔料）各色の適合性は視認上
での検討が在る以外主として樹脂材料の配合に留意すれ

て読み取りは可能に成る。The paint lacquer on the cloth tip is yellow [main component is lead chromate] ° and white [if heat-softening resin is limited with materials such as zinc oxide, the film thickness is 100-200 microns, and the effect is confirmed with some improvement. I can do it. Furthermore, if the coating method is improved and the surface gloss is improved, it will become possible to read it as logical information with an LED laser scanner, etc. as claimed in Section 2 of this application, except for red and black hues.

出来る方法論である。Since the reflection on the surface of the material and the reflectance of the metamorphosed parts are different, the conditions are perfect for it to be legible as logical electrical information, and furthermore, the printing effect, including visual identification, is recognized. The logical way to read the information is to check the reflection and diffuse reflection of a light beam with a specific wavelength [a light beam with a narrow spectral range], or to search based on reflection and absorption [contrast]. A method that can read even the diffuse reflection that occurs in metamorphic parts as logical information is a methodology that can contribute to both visual perception and information if it can be put into practical use along with effective visual recognition.

。[Claims] 1. A method of printing by irradiating a beam of light in the infrared region on the cured state of currently commonly used colored resins, paints, and printing inks containing metal compounds as main components [laser]. In the marking method, the metal compounds that are the main color pigments decompose and change color or turn into ash when exposed to light and heat, and the resin components used for peeling and abrasion resistance also naturally dissolve, burn, and change in quality. A method of distributing the combination of these two components mainly to improve visibility, which is effective for irradiating light beams in the infrared region. 2. A method of reading the difference in reflectance between the reflection on the surface of the non-irradiated part of the paint or printed matter processed by the method described in item 1 and the like and the part changed by the irradiation as logical information using a barcode reader or the like.
