Definitions
- FIG. 1 is a graph illustrating the relationship between the acid used for acylation, the degree of substitution of the OH groups by acyl groups, and the degree of polymerization for the production of a cellulosic ester. As is readily apparent by the area inside of the box, there is a wide range of acyl substitution which may be achieved.
- each X ⁇ is independently selected from -0-, -S-, or -N(R o) and A is selected from ethylene; propylene; trimethylene; and such groups substituted with C1-C4 alkyl, C1 -C4 alkoxy, aryl and cycloalkyl; 1,2-phenylene and 1,2-phenylene containing 1-3 substituents selected from
- the near infrared fluorophore compounds used to mark or tag the cellulosic ester should have excellent thermal stability and little light abso ⁇ tion in the visible region, i.e., about 400 nm to 700 nm range. Desirably, they should impart little or no color to the cellulosic ester. Also, the near infrared fluorophore should have strong abso ⁇ tion of near infrared light and have strong fluorescence in the near infrared wave lengths of about 670 nm to 2500 nm. Suitable stability to sunlight and fluorescent light and low extractability or sublimation from the cellulosic ester are also preferred.
- the near infrared fluorophore in the paste has a particle size less than about 50 microns, preferably less than about 30 microns, more preferably from about 0.1 microns to about 25 microns and most preferably from about 0.5 microns to about 10 microns.
- the amount of near infrared fluorophore compound dissolved in the strong acid is dependent upon the amount of marker which is to be inco ⁇ orated into the cellulose ester.
- the amount of invisible marker which is inco ⁇ orated into the cellulose ester will vary depending upon the particular near infrared fluorophore used.
- the visible color imparted to the cellulosic ester which may be inherent in the various markers. It is generally desired that the concentration of the near infrared fluorophore be low enough that it does not impart significant visible color to the finished article, or does not change the visual appearance of a colored object which contains the near infrared fluorophore.
- the marked cellulose ester of the present invention may be distinguished from non- marked cellulose ester by exposing the marked cellulose ester to radiation and detecting the fluorescence given off by the marked cellulose ester.
- the general principle of the operation and a description of a preferred apparatus which is useful for the identification of the near infrared markers present in the cellulose esters of this invention is described in U. S. Patent 5,397,819. The various components of the apparatus are readily available.
