. The present invention relates to a method of labeling, and it particularly relates to a method of attaching labels or other designating devices to sheets of cellulosic composia tions or similar materials. Much difiiculty has been experienced in satisfactorily attaching labels of paper, cloth or other materials to cellulosic films such as cellophane A great amount of the'difiiculty has been due to to the fact that satisfactory adhesives or adhesive compositions have not been developed. The usual adhesive mixtures, such as dextrine, lue or other water soluble colloids are generafil unsatisfactory and do not result label or designating strip to the base material.
The object of this invention is to provide an improvedmethodof attaching labels to sheets of cellulosic materials. 7
Another object of this invention is to provide-new and improved methods of adhesively attaching paper or cloth labels to transparent oellulosic films such cellophane. r
A further object of this invention is to provide an improved method of adhesion of general'utilit A still f urther object of the present invention is to provide new, and more satisfactory adhesive compositions.
Other objects will appear during the course of the following specification.
i In the preferred embodiment of the invention, to which it is by no means restricted, a paper or cloth label isattached to a sheet of a cellulosic compound, or to a sheet. of a regenerated cellulosic material by-means of a' colloidal mixture, which is preferably not soluble in water per se. This oellulosic'film' -or sheet may be composed of esters or ethers of. cellulose, such as cellulose nitrate, cellulose acetate or ethoxycellulose, or on the other hand it may be composed of cellulose which is first converted into. the form of a compound similar to or difierent than those s 'ecified above and then" regenerated so as to cm a smooth transparent material. Theadhe Q sive attachments of the present invention are 3? le adhesive attachment of the 1 alcohol and about 5% wood. alcohol.
not only applicable, however, to sheets of course it is possible that other solvents such Application filed February 19, 1880. Serial No. 429,883.
cellulosic material above described .but in addition are applicable to attaching labels to materials which do not form adhesive connections with the ordinary water soluble adhesive materials. I
In carrying out the present invention, the back of the label is coated with a very thin layer of a natural or synthetic resinous material. 'For example, varnlshes orsolutions made from manila chips, dammar gum, no copal, shellac or synthetic resins ma be utilized to coat the back of the labels a specific example of the method of application of this thin layer of adhesive material, six and one-half pounds of manila m are" dis- 66 solved in one gallon of a special cutting alcohol and the resulting solution is applied to the back of the label. It will be noted that the preferred materials for the purpose of 4 the present invention are water insoluble ad- 7 hesive materials.
Before applying the label provided with this backing of water insoluble adhesive to the sheetof cellophane, the resinous adhesive material is thoroughly dried. In most cases it has been found satisfactory to store. the coated label fora substantial length of time, as a result of which the very thin coating ofresinous material will be aged. When it becomes desirable to attach the label to the sheet of cellophane, the adhesive resinous layer is moistened with a solution of a plasticizer in a readily volatile solvent. A wide variety of plasticizers may .be utilized, but preferably those plasticizers, which are also glycerol esters of fatty acids and/or which are iquid at ordinary temperatures, are applied. Plasticizers of this character are castor oil, sulphonated castor oil, boiled linseed oil, China wood oil, etc: Although many solvents have been used and many various plasticizers dis-- solved therein, the preferredmoistening'so- -lution is composed of castor oil and ethyl alcohol, which ethyl alcohol, may contain a small quantity of wood alcohol. One mix-- F ture which has been utilized very successfully, is a solution 0525a, castor oil and 75% alcohol,.thcv alcohol consisting of about eth as benzine, petroleum ether, etc. might also be utilized in place of or in addition to the solvents previously mentioned. W After the label has been moistened, it is then applied to the sheet of cellophane and is preferably pressed down so that there will he a close contact over the entire adhesive surface of the label. The adhesive mixture will form ,a very permanent tenacious connection after evaporation of the solvent and will remain in a ermanently sticky or gummy condition. T e adhesive connection is particularly satisfactory when oils such as castor oil, linseed oil and/or China wood oil are utilized, since these materials will form a 'very flexible but tough adhesive connection by combination with the resinous materials. It is obvious that many changes, variations and modifications may be made in the present invention without changing the essence thereof.
What is claimed is: 7 7 1. A method of adhesively attaching a paper label to a sheet of cellophane, which comprises coating the back of the label with a solution of manila gum in alcohol, permitting the alcohol to evaporate, moistening the residual resinous layer with a solution of castorloil in alcohol, and applying the moistened label to a sheet of cellophane.
2. A method of labeling which comprises placing a water insoluble resinous material upon the back of a label, drying said material, moistening the said dried material with a plgsficizer solution and then applying the a e 3. A method of adhesively attaching a paper label to a sheet of cellophane, which com rises coating'the back of the label with a se ution of a resinous material in a volatile solvent, permitting the solvent to evaporate, moistening the residual resinous layer with a solution of a plasticizer in a volatile solvent, and applying the moistened label to m a sheet of cellop ane."
