Abstract
The present invention relates to a near infrared ray absorbing agent for producing safe printing ink, which is mainly prepared by adding pigment green 1602 as a near infrared ray absorbing agent to printing ink. The near infrared ray absorbing agent can also act with other infrared ray absorbing agents comprising phthalocyanine and black carbon, and a color compounding range of safe printing ink is broadened. Color match becomes more convenient, and matchable colors are from light to deep, comprising from yellow, red, blue and green to purple and gray. The near infrared ray absorbing agent can be applied to notes and tickets comprising securities, certificates, etc.
Description
The present invention relates to the printing-ink field, particularly contain safety ink as near infrared ray absorption pigment.
In the prior art, use the existing many kinds of safety ink of near infrared ray absorption, Japanese Patent for example: used near infrared ray absorption is the blue or green class pigment of phthalein among the clear 59-138284, the printing ink that use contains this material prints various proof cards, bank note and security, just can be by checking to prevent correction or to forge.But because the color of the blue or green pigment of phthalein is dark and single, so can only the darker printing ink of production color, the color matching scope is also narrower, so use range is restricted, when for example needing to print certificate, the security of light colour or extraordinary tone sometimes, use the printing ink that contains the blue or green class pigment of phthalein just to have any problem.
The objective of the invention is to: a kind of pigment that contains as near infrared ray absorption is provided,, enlarges the use range of safety ink, satisfy various service requirementss to produce the safety ink of multiple color.
The objective of the invention is to reach like this: Pigment green 1602 is mixed colours with the blue or green class pigment of phthalein phthalein, carbon black, make the safety ink with near-infrared absorbing characteristic of multiple color.
Below the present invention is described in detail:
Pigment green 1602 pigment that Ceng Zuowei is common in the past uses, but has not utilized the performance of its absorption near infrared ray so far.The present invention mainly adopts Pigment green 1602 as the near infrared ray absorption in the safety ink, be used with other the blue or green class pigment of phthalein and carbon black again with near infrared ray absorbing energy, can make the color matching scope from shallow to deep by different needs, it is dark and single to overcome the blue or green class pigment color of phthalein, shortcoming that can only the dark printing ink of production color.
Safety ink of the present invention also can be made into single Ji Mo that constitutes with Pigment green 1602 earlier and mix use with the versicolor printing ink that does not contain other near infrared ray absorption again, make the printing ink that does not have the near-infrared absorbing characteristic originally possess the near-infrared absorbing characteristic, also Pigment green 1602 can be made into the printing ink use with other pigment such as the blue or green class pigment of phthalein or carbon blacks etc. as near infrared ray absorption.The prescription following (weight %) of base China ink:
Pigment green 1,602 35
Colloid calcium powder 5
Sylvic oil 60
Wherein the colloid calcium powder is a filler, makes suitable concentration of printing ink maintenance and good printing appropriateness, and sylvic oil is the low-melting ink vehicle as printing ink.The mixture of the above prescription back that stirs is suppressed on three-roller, promptly make the Ji Mo that contains Pigment green 1602.Mix assembly with other printing ink in use then; If with the blue or green class pigment of Pigment green 1602 and phthalein and carbon black as pigment with near-infrared absorbing characteristic, then adjust the ratio of various pigment in the required color depth, add again after colloid calcium powder and sylvic oil mix well, on three-roller, suppress, promptly can be made into the printing ink of a certain required color.So, just make printing ink have the characteristic of near-infrared absorbing, and can assorted one-tenth from shallow to deep, as yellow, red, blue, the green colors such as purple and ash that arrive, to satisfy the requirement of Valued Securities printing-ink, these two kinds of using method all can make the printing ink that contains Pigment green 1602 be matched to the color close or consistent with required color with other pigment ink that does not have the near-infrared absorbing characteristic, and promptly the printing ink that the spectral distribution difference of printing ink and color tristimulus values are identical is right; Certainly difference that also can be on demand and using separately.
Safety ink of the present invention has following characteristics: contain the restriction that is not subjected to mode of printing as the printing ink of the present invention of near infrared ray absorption pigment 1602, printings such as glue, concave, convex all can be used, and no matter are which kind of literal, figure can; Use easy near infrared ray recognizer to observe, clear can distinguishing, it is obvious to detect effect; The wide material sources of Pigment green 1602 do not need any additional processing, and stable performance; Particularly can be deployed into the printing ink of light colour and some are with green phase printing ink and colorant match, Pigment green 1602 is mixed colours with pigment such as pigment such as the blue or green class pigment of phthalein, carbon black that other has the near-infrared absorbing characteristic, can make the toning range extension, make near infrared absorbent compared with blue or green class of independent use phthalein or carbon black, the choice is more arranged, colorant match is convenient, color that can be assorted from shallow to deep, as yellow, red, blue, green to purple and grey; Usage quantity is few when configuration, but effect is obvious, helps color matching and toning.

1, a kind of safety ink mainly is made up of sylvic oil, pigment, it is characterized in that: Pigment green 1602 can be mixed colours and make multiple printing ink with near infrared absorption characteristic with the blue or green class pigment of phthalein, carbon black.
