Da sporzadzenia oryginalów przy spo¬ sobie powielania zapomoca golej plyty» zaprawionej kwasno lub obojetnie (tak zwany sposób opalograficzny), uzywa sie atramentów alkalicznych, wzglednie alka¬ licznej zaprawy tasm barwiacych; Do tego tfelu stosuje sie dotychczas przy sporza¬ dzaniu oryginalu atrament amonjakalny lub domieszki do atramentu alkaljów nie¬ lotnych lub ich weglanów i alkalicznie dzialajacych soli. Atramenty amonjakalne posiadaja braki z powodu lotnosci amo- v jaku, a atramenty z zawartoscia alkaljów nielotnych lub ich soli reaguja na zaprawe plyty tylko bardzo powoli, a jesli czulosc zaprawy plyty spotegowac, np. zapomoca dodania zwiazków rodanowych, to moga powstac smugi na bialem tle z powodu zbytniej czulosci plyty.Próby wykazaly, ze jesli wykonac prze¬ znaczony do powielenia oryginal atramen¬ tem lub farba z domieszka heksametyleno- tetraminu, to reakcja miedzy atramentem oryginalu a zaprawa plyty bedzie nadzwy¬ czaj doskonala, nadajac wobec nielotnosci heksametylenotetraminu nadzwyczaj na trwalosc wytworzonym w ten sposób far¬ bom atramentowym, wzglednie orygina¬ lowi.Wynalazek polega wiec na dodaniu heksametylenotetraminu do atramentów, farb i tym podobnych srodków do nasyca¬ nia tasm barwiacych.Domieszka ta jest szczególnie dobra dosporzadzania tasm barwiacych, nadaja¬ cych sie do wskazanego sposobu powiela¬ nia. Jezeli do zwykle stosowanych srodków do nasycania tasm barwiacych o dowolnym skladzie uzyc znacznej domieszki heksa- metylenotetraminu, np. 50%, to pismo wy¬ konane na maszynie przy pomocy tej tasmy wchodzi w dostatecznie energiczna reakcje z zaprawa plyty, przyczem nie po¬ trzeba wcale powiekszac czulosci tej ostatniej.Oczywiscie, sposób ten mozna zastoso¬ wac takze w razie sporzadzania oryginalu atramentem lepkim, np. oryginal sporza¬ dza sie na maszynie do pisania przy po¬ mocy tasmy barwiacej, zawierajacej sub¬ stancje kleiste, a nastepnie opyla sie go mieszanina, zawierajaca w stanie sproszko¬ wanym heksametylenotetramin lub jego sole. PL PLFor the production of originals by means of duplication with a bare plate, acid-proofed or neutral (the so-called opalography method), alkaline inks or a relatively alkaline mortar are used; Hitherto, ammoniacal ink or admixtures of non-volatile alkali or their carbonates and alkaline salts have been used for this layer in the original preparation. Ammoniacal inks are deficient due to the volatility of amo-v yak, and inks containing non-volatile alkali or their salts react to the plasterboard only very slowly, and if the sensitivity of the plasterboard mortar is increased, e.g. by adding rhodium compounds, streaks may appear on the white background Tests have shown that if you make the original ink to be duplicated or paint with hexamethylene tetramine admixture, the reaction between the original ink and the plaster mortar will be extremely excellent, giving the hexamethylenetetramine extremely durable against the non-volatile nature of Thus, the invention consists in adding hexamethylene tetramine to inks, paints and the like for impregnating the color ribbons. This admixture is particularly good for the preparation of color ribbons suitable for the indicated color. method of duplication. If, for the commonly used agents for impregnating dyeing ribbons of any composition, a significant admixture of hexamethylene tetramine, e.g. 50%, is used, then the typewriter made with this ribbon reacts with a sufficiently vigorous reaction with the plaster of the plate, so it is not necessary at all. Of course, this method can also be used when the original is made with sticky ink, e.g. the original is made on a typewriter with the help of a coloring ribbon containing sticky substances, and then it is sprayed a mixture containing in a powdered state hexamethylenetetramine or its salts.
