Abstract
A kind of heat-sensitive colour-changing ink, add a certain proportion of thermosensitive chromotropic paint by common ink, this heat-sensitive colour-changing ink has the heat of chance and the temperature rising changes color, thermal source is cancelled or temperature reduces the characteristics that original color is recovered in the back, the printing of producing with this ink printing is used for trade mark and product labelling, and ticket etc. can discern its true and false very easily, and it is convenient to use.
Description
The present invention is a kind of novel printing-ink, heat-sensitive colour-changing ink.
At present, the printing ink that is used to print mostly is the stable printing ink of various physico chemical factors greatly, does not change its physics, chemical property when circuitous heat, temperature variation.During with this class ink printing, when the printed matter of producing was used for the mark of trade mark or product, trade mark and product were difficult for distinguishing true from false.Ultraviolet ink has also appearred in recent years, this printing ink can change color and send out jade-like stone, phosphorescence under the irradiation of ultraviolet, help the commodity of distinguishing true from false though under ultraviolet light irradiation, can change color with the trade mark of this ultraviolet ink printing, but range of application is restricted, can only be applicable to sales department and technical supervision department, ordinary consumer is difficult to check the commodity of distinguishing true from false.
The objective of the invention is to, propose the heat-sensitive colour-changing ink that the rising of a kind of circuitous thermal source or temperature can change color, to solve the deficiency of existing printing ink a few days ago.When being used for trade mark and product labelling with the printed matter of this printing ink production, people can discern its true and false very easily.
Major technique content of the present invention is that this heat-sensitive colour-changing ink has circuitous thermal source or elevated temperature can become color, thermal source withdraw from or lower the temperature after can reply the characteristics of original color.
Technical scheme of the present invention is, doses a certain proportion of thermosensitive chromotropic paint in common ink, evenly is heat-sensitive colour-changing ink through the specific equipment agitation grinding.Thermosensitive chromotropic paint is the emerging pigment of Chinese Academy of Sciences's development.
Technique effect of the present invention is, it is simple that this heat-sensitive colour-changing ink has production technique, advantage easy to use, use this ink printing, the printed matter of producing can be widely used in the show one's color printing of technology printing, secret document and various heat-sensitive variable colour marks of trade mark, product labelling, various card volume, temperature rise, can discern its true and false easily.So this printing ink is a kind of multi-functional, multiduty novel ink.
Realize that preferred plan of the present invention is, in common printing ink, dose 3%～40% thermosensitive chromotropic paint, even through the specific equipment agitation grinding, promptly can be heat-sensitive colour-changing ink.
Claims (3)
1, a kind of printing-ink, heat-sensitive colour-changing ink is characterized in that, and thermal source crossed by this printing ink or elevated temperature changes color, and thermal source is withdrawn from or temperature reduces the characteristics of recovering original color.
2, the described heat-sensitive colour-changing ink of claim 1 is characterized in that the production technique of this printing ink is, doses thermosensitive chromotropic paint in general printing ink, and is even through the specific equipment agitation grinding.
3, the production technique of heat-sensitive colour-changing ink according to claim 2, the part by weight that it is characterized in that dosing thermosensitive chromotropic paint is 3%～40%.
