| titleOfInvention | Improvements relating to fluorescent foils |
| abstract | Fluorescent foils consist of polymeric synthetic materials incorporating organically soluble fluorescent brightening agents at 0.1-1.0% total weight and in addition water-in-soluble non-fluorescent dyestuffs or pigments at 0.001-0.5%, the ratio of the former to the latter being greater than unity, preferably 10 or more. Rolling and heating are used in the production of the foils or the incorporation of the additives. Polymeric materials.-Polyvinyl chloride polyethylene or polystyrene with plasticizers such as dialkyl phthalates, sebacates or adipates, or triaryl phosphates. Di-butyl tin di-laurate is added to P.V.C. in examples. Brightening agents.-Preferred are those of the stilbene series which contain a negative substituent in at least one of the o-positions to the ethylene bridge and a 4.5-arylo-1.2.3-triazolyl-(2) radical in at least one p-position; examples are the 4 - [(naptho - 11.21:4.5) - 1.2.3 - triazolyl - (2)] - stilbene - 2 - or - 21 - sulphonic acid amides (such as cyclohexylamide) or aryl esters e.g. of phenol, cresol or xylenol. Specific examples refer to 4.41 - bis - ((11.21:4.5-naphtho) - 1.2.3 - triazolyl - (2) - ] - stilbene-2.21 - bis - sulphonic acid dibutyl amide, or to the 1.4-bis-form. Other brightening agents used may be 4.5-diphenyl-dihydroimidazole-2-one; 1.3 - diaryl - (such as diphenyl) and 1.3.5 - tri-aryl - pyrazolines; 7 - aminocoumarins (such as 7 - ethyl amino - 4 - methyl - coumarin); bis - benzimidazolyl - (2) - ethylenes; oxacyanines; styryl oxadiazoles; 4-styryl-1-phenyl pyrazolines. Specific examples refer to 3.31.5.51 - tetramethyl - oxacyanine methosulphate; bis - (41.51 - diphenyl - furano - 21.31) benzene or 1.4-bis-(41-lauroyl-amino-21-phenyl sulphonyl styryl) benzene; 1 - phenyl - 3-(41 - methoxy - styryl) - 5 - (41 - methoxy phenyl) pyrazoline. Dyestuffs and pigments.-Alkaline earth or manganese dye lacquers from o-sulphonic acid phenyl azo compounds; azo pigments, halogen-free or halogenated phthalocyanines and copper cobalt or nickel complexes thereof; inorganic pigments such as cadmium red or chromic oxide green; fat-soluble diazotized p-amino-benzenes with 2-naphthol. Specific examples refer to the disazo product of 2 mols. diazotized 2.4 - dichloro - aniline and 1 mol. 4.41 - bis-aceloacetylamino - 3.31 - dimethyl diphenyl; manganese lacquer of 2 - chloro - 4 - amino - 1 - methylbenzene - 5 - sulphonic acid or calcium lacquer of 4 - amino - 1 methylbenzene - 3 - sulphonic acid, each with 2.3-hydroxynaphthoic acid. The products are stated to be suitable for decoration, wrappings, raincoats or household articles and produce shot effects. |
