Abstract
A new covert security feature for paper/polymeric substrates using a coating/marking ink which have sharp and distinct infra-red absorption is disclosed herein. Further, the invention discloses a method for incorporating the said security markers into the substrate and the use for authentication thereof.
Claims
1. (original) A composition comprising 0.1-70% of one or more covert security marker compounds selected from the group comprising of compound of general formula (I)
General formula I
Wherein, 'A' represents a phenyl group or an alkali metal or heteroaryl group; Ri arid R2 are selected independently of each other from hydrogen, halogen, - OH, -N02, -COOH, -CH2Br, -C≡C-Br;
R3 represents -C≡N or N"=N+=N'; with the provisio, when R3 is N"=N+=N", A is an alkali metal; When R3 is C≡N, A represents phenyl or heteroaryl group which may be substituted or unsubstituted.
β-alanine or potassium ferri cyanide along with 30-99.9% acceptable ingredients characterized by having at least one sharp and distinct infra-red absorption in wave number region 1800-2500 cm"1 for identification and authentication of articles, such that the authentication is possible accurately in less than five scans.
2. (original) The covert security marker composition according to claim 1, wherein the representative compounds of are selected from a group of substituted benzonitriles of general formula (II)
Formula II
Wherein, Rl and R2 are selected independently of each other from hydrogen, halogen, -OH, -N02, -COOH, -CH2Br.
3. (Amended) The covert security marker composition according to claim 1, wherein representative compounds of formula I is selected from
i. 4-chloro-3-nitrobenzonitrile;
ii. 3-(Bromomethyl)benzonitrile;
iii. Sodium Azide;
iv. 4-Hydroxybenzonitrile;

4. (original) The covert security marker composition as claimed in claim 1, wherein acceptable ingredients is selected from the group consisting of resins, inks, surfactants, thinners, binders and such like.
5. (original) The covert security marker composition as claimed in claim 1, wherein the IR markers are used either alone or in combination thereof.
6. (original) The covert security marker composition according to claim 1, wherein the covert security marker compounds are incorporated into the article or are applied on to the article for identification and authentication of articles.
7. (original) The covert security markers composition according to claim 1, wherein the method for authenticating an article comprises steps of;
a. providing fine powder of IR marker compounds, which when exposed to radiation in wave number region 1800-2500 cm"1 exhibits at least one peak at said wave number in the IR region, wherein at-least one of said peaks define a signature for authentication;
b. mixing said IR marker(s) with acceptable ingredients wherein said ingredients does not show absorption in the said IR region;
c. coating the mixture as obtained in step (b) uniformly on to the article to be authenticated using Doctor blade method;
d. injecting ink loaded with the IR marker(s) in an empty cartridge of an inkjet printer used to print on paper; or
e. injecting ink loaded with the IR marker(s) in an empty cartridge of an inkjet printer;
f. analyzing said marker(s) using a micro Attenuated Total reflection (ATR) - FTIR to determine the existence of said signatures to authenticate the said article.
8. (original) Use of covert security marker compounds characterized in having at least one sharp and distinct infra-red absorption in wave number region 1800-2500 cm"1 for identification and authentication of products/articles wherein said security markers are selected from compound of general formula (I), β-alanine or potassium ferri cyanide
General formula I
Wherein, 'A' represents a phenyl group or an alkali metal or heteroaryl group;
Ri and R2 are selected independently of each other from hydrogen, halogen, -OH, -
N02, -COOH, -CH2Br, -C≡C-Br;
R3 represents -C≡N or N"=N+=N"; with the provisio, when R3 is N"=N+=N", A is an alkali metal; When R3 is C≡N, A represents phenyl or heteroaryl group which may be substituted or unsubstituted.
9. (original) The use according to claim 8, wherein covert security markers may be used either alone or in combination thereof.
10. (original) A method for identification and authentication of an article/ products comprising incorporating covert security markers characterized by having a sharp and distinct infra-red absorption in wave number region 1800-2500 cm-1 into the article/product or applying the markers on to the article/product.
1 1. (original) The method according to claim 10, wherein the covert security markers may be used either alone or in combination thereof.
32
12. (original) The method according to claim 10, wherein the concentration of the covert security markers in the range of 0.1-70% that may be incorporated or may be applied onto the article/product for identification and authentication.
