5 cl ims. (Cl. 260-2471) The invention here presented is anew whitener in the form of a dye type of substance which is fluorescent under ultra violet to yield a brilliant bluish white fluorescence, which agent is found in the triaz inostilbene series. a
It is well known that cellulosic materials such as paper, cotton textiles and the like have a slight yellowish hue which, particularly in the case of textile materials, is apt to become more pronounced when the material is subjected to repeated launderings and use. Accordingly, it has long been the practice to treat many white cotton textiles, when they are washed, with a bluing substance, such as ultramarine. It has been'found that the slight blue coloration thus imparted to the material compensates for the yellowish tint or similar off-white shade of the material so that it appears whiter; such bluing operations, however, result in the absorption of a measurable portion of the total visible light falling upon the treated material and, accordingly, the treated material has a silghtly dull appearance. 7 I It has recently been proposed to treat paper or cotton textiles and similar cellulosic materials with agents which, while themselves colorless, fluoresce in the blue range of the spectrum so that in daylight or other light, which includes ultra violet radiation, the fluorescence of the treating agent compensates for the slight yellowish tint or similar oil-white shade, the blue'being complementary to yellow. Such fluorescent agents only absorb, a negligible portion of the visible light falling on the material and, accordingly, as a result-of the fluorescence the treated material is much brighter as well as whiter in appearance.
While a wide variety of fluorescent agents have been suggested for treatment of fibrous materials, it has been found that for the treatment of cellulosic materials, either paper or textiles, the use of fluorescent agents which are substantive to cellulose is preferable since by'the use of substantive fluorescent agents a whitening or brightening the material so that after drying the material appears much whiter and brighter than untreated materials.
These fluorescent brightening agents are also useful in treating textile materials which are to be, or have been dyed or printed withdischarge paste. The whites of the materials so printed with pastes containing brightening agents are much whiter than is otherwise the case.
While numerous fluorescent bleaching or brightening agents have heretofore been suggested, including diaminostilbene sulfonic and carhoxylic acids and certain acylated derivatives thereof, only a few of them have been satis factory, particularly for use by incorporation in soap or other detergents. Inorder to be satisfactory for use as a brightening agentto be incorporated with soap or similar ground of photographic prints and diazotype prints can be i coating emulsions.
. charge pastes, the whites obtained upon discharge are decidedly whiter than those discharges made in the abfabrics.
should be itself colorless, or nearly so, and must not stain yellow tints to thetreated fabric. It must also have a proper degree of substantivity towards the materials as too small adegree of substantivity renders it valueless as if would be'removed in any rinse waters, and too high a degree of substantivity results in a gradual build-up of fluorescent agent on material during repeated launderings resulting in off-color shades. The fluorescent agent must be stable to light and notdiscolor on exposure. ,It must be stable to hyp'o-chlorite treatment,andnotj discolor under suchtreatment, and in addition, it must fluoresce overa fairly wide pH differential, including both alkali and acid. W The present invention presents a series of compounds which have some of the characteristics of dyestuffs or pigments, which in addition show a strong bluish white fiuoresence of out-standing brilliance, which compounds in addition are readily incorporated into a wide range. of fabrics, fibers, felted materials and paper, to yield an outstanding whiteness in the material to which they are applied. .This material is a triazinostilbene compound containing a semicarbazide group with an associated alkyl amino group. Broadly the compound has the following molecular structure:

other' objects' and details of theinvention will be apparent from thefollowing description.
" The following examples show the preferred method of practising the invention but various modifications will be obvious to those skilled in the art.
Example I Thirty-seven parts of'cyanuric' chloride are dissolved in 120 parts of acetone and poured into a mixture of ice and water; During the suspension in ice water, the temperatureof the aqueous suspension should not rise above 5 C. Thirty-seven parts of 4,4-diaminostilbene-2,2-disulfonic acid are dissolved in 150 parts of water with the additionof enough sodium carbonate to give a neutral The materialwhich is obtained is slightly tan in color and moderately soluble in water but very slightly soluble in acetone, alcohol, ether, etc.
Example 11 The procedure of Example I was repeated up to and including the end of the secondary condensation whereupon, instead of adding 56 parts of morpholine, 142 parts of a 33% aqueous solution of dimethylamine were added and the pH increased to 7.5 to 7.8 with sodium carbonate solution. Then the mixture was heated slowly to 65 C. and maintained at that temperature for 8 hours, as before. Upon cooling and separating the product a material was obtained corresponding to the formula:
The material which is obtained is slightly tan in color and moderately soluble in water but very slightly soluble in acetone, alcohol, ether and the like.
Example Ill The procedure of Example I was repeated up to and including the secondary condensation; then instead of adding. 56 parts of morpholine, 73 parts of diethylamine were addedand the material neutralized and heated as be fore to yield a product corresponding to the formula:

The mixture is allowed to warm to room temperature and may be heated to 35-40 C. ifnecessary to complete the condensation. When this secondary, condensation is complete, 56 parts of morpholineare added and the pH is increased to 7.5-8 with sodium carbonatesolution.
